On some target machines, GCC supports many built-in functions specific to those machines. Generally these generate calls to specific machine instructions, but allow the compiler to schedule those calls.

These built-in functions are available for the AArch64 family of processors.

```
unsigned int __builtin_aarch64_get_fpcr ()
void __builtin_aarch64_set_fpcr (unsigned int)
unsigned int __builtin_aarch64_get_fpsr ()
void __builtin_aarch64_set_fpsr (unsigned int)
```

These built-in functions are available for the Alpha family of processors, depending on the command-line switches used.

The following built-in functions are always available. They all generate the machine instruction that is part of the name.

The following built-in functions are always available. They
all generate a Nios II Custom Instruction. The name of the
function represents the types that the function takes and
returns. The letter before the `n` is the return type
or void if absent. The `n` represents the first parameter
to all the custom instructions, the custom instruction number.
The two letters after the `n` represent the up to two
parameters to the function.

The letters represent the following data types:

The following built-in functions are provided for ARC targets. The built-ins generate the corresponding assembly instructions. In the examples given below, the generated code often requires an operand or result to be in a register. Where necessary further code will be generated to ensure this is true, but for brevity this is not described in each case.

*Note:* Using a built-in to generate an instruction not supported
by a target may cause problems. At present the compiler is not
guaranteed to detect such misuse, and as a result an internal compiler
error may be generated.

Built-in Functionint__builtin_arc_aligned(void*``val``,int``alignval``)Return 1 if `val` is known to have the byte alignment given
by `alignval`, otherwise return 0.
Note that this is different from

`__alignof__(*(char *)``val``) >= alignval`

because __alignof__ sees only the type of the dereference, whereas __builtin_arc_align uses alignment information from the pointer as well as from the pointed-to type. The information available will depend on optimization level.

built-in.

Built-in Functionvoid__builtin_arc_core_write(unsignedint``regno``,unsignedint``val``)The first operand is the number of a register to be written, the second operand is a compile time constant to write into that register. Generates:

The instructions generated by the following builtins are not considered as candidates for scheduling. They are not moved around by the compiler during scheduling, and thus can be expected to appear where they are put in the C code:

```
__builtin_arc_brk()
__builtin_arc_core_read()
__builtin_arc_core_write()
__builtin_arc_flag()
__builtin_arc_lr()
__builtin_arc_sleep()
__builtin_arc_sr()
__builtin_arc_swi()
```

SIMD builtins provided by the compiler can be used to generate the
vector instructions. This section describes the available builtins
and their usage in programs. With the *-msimd* option, the
compiler provides 128-bit vector types, which can be specified using
the `vector_size` attribute. The header file arc-simd.h
can be included to use the following predefined types:

```
typedef int __v4si __attribute__((vector_size(16)));
typedef short __v8hi __attribute__((vector_size(16)));
```

These types can be used to define 128-bit variables. The built-in functions listed in the following section can be used on these variables to generate the vector operations.

For all builtins, `__builtin_arc_``someinsn```, the header file
arc-simd.h also provides equivalent macros called
`_``someinsn``` that can be used for programming ease and
improved readability. The following macros for DMA control are also
provided:

```
#define _setup_dma_in_channel_reg _vdiwr
#define _setup_dma_out_channel_reg _vdowr
```

The following is a complete list of all the SIMD built-ins provided for ARC, grouped by calling signature.

GCC implements extensions for C as described in the ARM C Language Extensions (ACLE) specification, which can be found at http://infocenter.arm.com/help/topic/com.arm.doc.ihi0053c/IHI0053C_acle_2_0.pdf.

As a part of ACLE, GCC implements extensions for Advanced SIMD as described in the ARM C Language Extensions Specification. The complete list of Advanced SIMD intrinsics can be found at http://infocenter.arm.com/help/topic/com.arm.doc.ihi0073a/IHI0073A_arm_neon_intrinsics_ref.pdf. The built-in intrinsics for the Advanced SIMD extension are available when NEON is enabled.

Currently, ARM and AArch64 back ends do not support ACLE 2.0 fully. Both back ends support CRC32 intrinsics from arm_acle.h. The ARM back end’s 16-bit floating-point Advanced SIMD intrinsics currently comply to ACLE v1.1. AArch64’s back end does not have support for 16-bit floating point Advanced SIMD intrinsics yet.

See ARM Options and AArch64 Options for more information on the availability of extensions.

These built-in functions are available for the ARM family of processors with floating-point unit.

```
unsigned int __builtin_arm_get_fpscr ()
void __builtin_arm_set_fpscr (unsigned int)
```

For each built-in function for AVR, there is an equally named,
uppercase built-in macro defined. That way users can easily query if
or if not a specific built-in is implemented or not. For example, if
`__builtin_avr_nop` is available the macro
`__BUILTIN_AVR_NOP` is defined to `1` and undefined otherwise.

The following built-in functions map to the respective machine
instruction, i.e. `nop`, `sei`, `cli`, `sleep`,
`wdr`, `swap`, `fmul`, `fmuls`
resp. `fmulsu`. The three `fmul*` built-ins are implemented
as library call if no hardware multiplier is available.

```
void __builtin_avr_nop (void)
void __builtin_avr_sei (void)
void __builtin_avr_cli (void)
void __builtin_avr_sleep (void)
void __builtin_avr_wdr (void)
unsigned char __builtin_avr_swap (unsigned char)
unsigned int __builtin_avr_fmul (unsigned char, unsigned char)
int __builtin_avr_fmuls (char, char)
int __builtin_avr_fmulsu (char, unsigned char)
```

In order to delay execution for a specific number of cycles, GCC implements

```
void __builtin_avr_delay_cycles (unsigned long ticks)
```

`ticks` is the number of ticks to delay execution. Note that this
built-in does not take into account the effect of interrupts that
might increase delay time. `ticks` must be a compile-time
integer constant; delays with a variable number of cycles are not supported.

```
char __builtin_avr_flash_segment (const __memx void*)
```

This built-in takes a byte address to the 24-bit
AVR Named Address Spacesaddress space `__memx` and returns
the number of the flash segment (the 64 KiB chunk) where the address
points to. Counting starts at `0`.
If the address does not point to flash memory, return `-1`.

```
unsigned char __builtin_avr_insert_bits (unsigned long map, unsigned char bits, unsigned char val)
```

Insert bits from `bits` into `val` and return the resulting
value. The nibbles of `map` determine how the insertion is
performed: Let `X` be the `n`-th nibble of `map`

- If
`X`is`0xf`, then the`n`-th bit of`val`is returned unaltered. - If X is in the range 0...7,
then the
`n`-th result bit is set to the`X`-th bit of`bits` - If X is in the range 8...``0xe``,
then the
`n`-th result bit is undefined.

One typical use case for this built-in is adjusting input and output values to non-contiguous port layouts. Some examples:

```
// same as val, bits is unused
__builtin_avr_insert_bits (0xffffffff, bits, val)
```

```
// same as bits, val is unused
__builtin_avr_insert_bits (0x76543210, bits, val)
```

```
// same as rotating bits by 4
__builtin_avr_insert_bits (0x32107654, bits, 0)
```

```
// high nibble of result is the high nibble of val
// low nibble of result is the low nibble of bits
__builtin_avr_insert_bits (0xffff3210, bits, val)
```

```
// reverse the bit order of bits
__builtin_avr_insert_bits (0x01234567, bits, 0)
```

Currently, there are two Blackfin-specific built-in functions. These are
used for generating `CSYNC` and `SSYNC` machine insns without
using inline assembly; by using these built-in functions the compiler can
automatically add workarounds for hardware errata involving these
instructions. These functions are named as follows:

```
void __builtin_bfin_csync (void)
void __builtin_bfin_ssync (void)
```

GCC provides many FR-V-specific built-in functions. In general,
these functions are intended to be compatible with those described
by FR-V Family, Softune C/C++ Compiler Manual (V6), Fujitsu
Semiconductor. The two exceptions are `__MDUNPACKH` and
`__MBTOHE`, the GCC forms of which pass 128-bit values by
pointer rather than by value.

Most of the functions are named after specific FR-V instructions. Such functions are said to be ‘directly mapped’ and are summarized here in tabular form.

The arguments to the built-in functions can be divided into three groups: register numbers, compile-time constants and run-time values. In order to make this classification clear at a glance, the arguments and return values are given the following pseudo types:

Pseudo type | Real C type | Constant? | Description |
---|---|---|---|

uh |
unsigned short |
No | an unsigned halfword |

uw1 |
unsigned int |
No | an unsigned word |

sw1 |
int |
No | a signed word |

uw2 |
unsigned long long |
No | an unsigned doubleword |

sw2 |
long long |
No | a signed doubleword |

const |
int |
Yes | an integer constant |

acc |
int |
Yes | an ACC register number |

iacc |
int |
Yes | an IACC register number |

These pseudo types are not defined by GCC, they are simply a notational convenience used in this manual.

Arguments of type `uh`, `uw1`, `sw1`, `uw2`
and `sw2` are evaluated at run time. They correspond to
register operands in the underlying FR-V instructions.

`const` arguments represent immediate operands in the underlying
FR-V instructions. They must be compile-time constants.

`acc` arguments are evaluated at compile time and specify the number
of an accumulator register. For example, an `acc` argument of 2
selects the ACC2 register.

`iacc` arguments are similar to `acc` arguments but specify the
number of an IACC register. See see *other-built-in-functions*
for more details.

The functions listed below map directly to FR-V I-type instructions.

This sections describes built-in functions related to read and write
instructions to access memory. These functions generate
`membar` instructions to flush the I/O load and stores where
appropriate, as described in Fujitsu’s manual described above.

`unsigned char __builtin_read8 (void * data)`

void __builtin_write8 (void *data, unsigned chardatum)void __builtin_write16 (void *data, unsigned shortdatum)void __builtin_write32 (void *data, unsigned longdatum)void __builtin_write64 (void *.. _other-built-in-functions:data, unsigned long longdatum)

This section describes built-in functions that are not named after a specific FR-V instruction.

`sw2 __IACCreadll (iacc`*reg*)- Return the full 64-bit value of IACC0. The
`reg`argument is reserved for future expansion and must be 0. `sw1 __IACCreadl (iacc`*reg*)- Return the value of IACC0H if
`reg`is 0 and IACC0L if`reg`is 1. Other values of`reg`are rejected as invalid. `void __IACCsetll (iacc`*reg*, sw2*x*)- Set the full 64-bit value of IACC0 to
`x`. The`reg`argument is reserved for future expansion and must be 0. `void __IACCsetl (iacc`*reg*, sw1*x*)- Set IACC0H to
`x`if`reg`is 0 and IACC0L to`x`if`reg`is 1. Other values of`reg`are rejected as invalid. `void __data_prefetch0 (const void *`*x*)- Use the
`dcpl`instruction to load the contents of address`x`into the data cache. `void __data_prefetch (const void *`*x*)- Use the
`nldub`instruction to load the contents of address`x`into the data cache. The instruction is issued in slot I1.

The MIPS DSP Application-Specific Extension (ASE) includes new instructions that are designed to improve the performance of DSP and media applications. It provides instructions that operate on packed 8-bit/16-bit integer data, Q7, Q15 and Q31 fractional data.

GCC supports MIPS DSP operations using both the generic
vector extensions (see *Using Vector Instructions through Built-in Functions*) and a collection of
MIPS-specific built-in functions. Both kinds of support are
enabled by the *-mdsp* command-line option.

Revision 2 of the ASE was introduced in the second half of 2006.
This revision adds extra instructions to the original ASE, but is
otherwise backwards-compatible with it. You can select revision 2
using the command-line option *-mdspr2*; this option implies
*-mdsp*.

The SCOUNT and POS bits of the DSP control register are global. The WRDSP, EXTPDP, EXTPDPV and MTHLIP instructions modify the SCOUNT and POS bits. During optimization, the compiler does not delete these instructions and it does not delete calls to functions containing these instructions.

At present, GCC only provides support for operations on 32-bit
vectors. The vector type associated with 8-bit integer data is
usually called `v4i8`, the vector type associated with Q7
is usually called `v4q7`, the vector type associated with 16-bit
integer data is usually called `v2i16`, and the vector type
associated with Q15 is usually called `v2q15`. They can be
defined in C as follows:

```
typedef signed char v4i8 __attribute__ ((vector_size(4)));
typedef signed char v4q7 __attribute__ ((vector_size(4)));
typedef short v2i16 __attribute__ ((vector_size(4)));
typedef short v2q15 __attribute__ ((vector_size(4)));
```

`v4i8`, `v4q7`, `v2i16` and `v2q15` values are
initialized in the same way as aggregates. For example:

```
v4i8 a = {1, 2, 3, 4};
v4i8 b;
b = (v4i8) {5, 6, 7, 8};
v2q15 c = {0x0fcb, 0x3a75};
v2q15 d;
d = (v2q15) {0.1234 * 0x1.0p15, 0.4567 * 0x1.0p15};
```

*Note:* The CPU’s endianness determines the order in which values
are packed. On little-endian targets, the first value is the least
significant and the last value is the most significant. The opposite
order applies to big-endian targets. For example, the code above
sets the lowest byte of `a` to `1` on little-endian targets
and `4` on big-endian targets.

*Note:* Q7, Q15 and Q31 values must be initialized with their integer
representation. As shown in this example, the integer representation
of a Q7 value can be obtained by multiplying the fractional value by
`0x1.0p7`. The equivalent for Q15 values is to multiply by
`0x1.0p15`. The equivalent for Q31 values is to multiply by
`0x1.0p31`.

The table below lists the `v4i8` and `v2q15` operations for which
hardware support exists. `a` and `b` are `v4i8` values,
and `c` and `d` are `v2q15` values.

C code | MIPS instruction |
---|---|

a + b |
addu.qb |

c + d |
addq.ph |

a - b |
subu.qb |

c - d |
subq.ph |

The table below lists the `v2i16` operation for which
hardware support exists for the DSP ASE REV 2. `e` and `f` are
`v2i16` values.

C code | MIPS instruction |
---|---|

e * f |

It is easier to describe the DSP built-in functions if we first define the following types:

```
typedef int q31;
typedef int i32;
typedef unsigned int ui32;
typedef long long a64;
```

`q31` and `i32` are actually the same as `int`, but we
use `q31` to indicate a Q31 fractional value and `i32` to
indicate a 32-bit integer value. Similarly, `a64` is the same as
`long long`, but we use `a64` to indicate values that are
placed in one of the four DSP accumulators (`$ac0`,
`$ac1`, `$ac2` or `$ac3`).

Also, some built-in functions prefer or require immediate numbers as parameters, because the corresponding DSP instructions accept both immediate numbers and register operands, or accept immediate numbers only. The immediate parameters are listed as follows.

```
imm0_3: 0 to 3.
imm0_7: 0 to 7.
imm0_15: 0 to 15.
imm0_31: 0 to 31.
imm0_63: 0 to 63.
imm0_255: 0 to 255.
imm_n32_31: -32 to 31.
imm_n512_511: -512 to 511.
```

The MIPS64 architecture includes a number of instructions that operate on pairs of single-precision floating-point values. Each pair is packed into a 64-bit floating-point register, with one element being designated the ‘upper half’ and the other being designated the ‘lower half’.

GCC supports paired-single operations using both the generic
vector extensions (see *Using Vector Instructions through Built-in Functions*) and a collection of
MIPS-specific built-in functions. Both kinds of support are
enabled by the *-mpaired-single* command-line option.

The vector type associated with paired-single values is usually
called `v2sf`. It can be defined in C as follows:

```
typedef float v2sf __attribute__ ((vector_size (8)));
```

`v2sf` values are initialized in the same way as aggregates.
For example:

```
v2sf a = {1.5, 9.1};
v2sf b;
float e, f;
b = (v2sf) {e, f};
```

*Note:* The CPU’s endianness determines which value is stored in
the upper half of a register and which value is stored in the lower half.
On little-endian targets, the first value is the lower one and the second
value is the upper one. The opposite order applies to big-endian targets.
For example, the code above sets the lower half of `a` to
`1.5` on little-endian targets and `9.1` on big-endian targets.

GCC provides intrinsics to access the SIMD instructions provided by the
ST Microelectronics Loongson-2E and -2F processors. These intrinsics,
available after inclusion of the `loongson.h` header file,
operate on the following 64-bit vector types:

`uint8x8_t`, a vector of eight unsigned 8-bit integers;`uint16x4_t`, a vector of four unsigned 16-bit integers;`uint32x2_t`, a vector of two unsigned 32-bit integers;`int8x8_t`, a vector of eight signed 8-bit integers;`int16x4_t`, a vector of four signed 16-bit integers;`int32x2_t`, a vector of two signed 32-bit integers.

The intrinsics provided are listed below; each is named after the machine instruction to which it corresponds, with suffixes added as appropriate to distinguish intrinsics that expand to the same machine instruction yet have different argument types. Refer to the architecture documentation for a description of the functionality of each instruction.

GCC provides other MIPS-specific built-in functions:

`void __builtin_mips_cache (int`*op*, const volatile void **addr*)- Insert a
`cache`instruction with operands`op`and`addr`. GCC defines the preprocessor macro`___GCC_HAVE_BUILTIN_MIPS_CACHE`when this function is available. `unsigned int __builtin_mips_get_fcsr (void)``void __builtin_mips_set_fcsr (unsigned int`*value*)Get and set the contents of the floating-point control and status register (FPU control register 31). These functions are only available in hard-float code but can be called in both MIPS16 and non-MIPS16 contexts.

`__builtin_mips_set_fcsr`can be used to change any bit of the register except the condition codes, which GCC assumes are preserved.

GCC provides a couple of special builtin functions to aid in the writing of interrupt handlers in C.

`__bic_SR_register_on_exit (int`*mask*)- This clears the indicated bits in the saved copy of the status register currently residing on the stack. This only works inside interrupt handlers and the changes to the status register will only take affect once the handler returns.
`__bis_SR_register_on_exit (int`*mask*)- This sets the indicated bits in the saved copy of the status register currently residing on the stack. This only works inside interrupt handlers and the changes to the status register will only take affect once the handler returns.
`__delay_cycles (long long`*cycles*)- This inserts an instruction sequence that takes exactly
`cycles`cycles (between 0 and about 17E9) to complete. The inserted sequence may use jumps, loops, or no-ops, and does not interfere with any other instructions. Note that`cycles`must be a compile-time constant integer - that is, you must pass a number, not a variable that may be optimized to a constant later. The number of cycles delayed by this builtin is exact.

These built-in functions are available for the NDS32 target:

Built-in Functionvoid__builtin_nds32_isync(int*``addr``)Insert an ISYNC instruction into the instruction stream where
`addr` is an instruction address for serialization.

Built-in Functionvoid__builtin_nds32_isb(void)Insert an ISB instruction into the instruction stream.

Built-in Functionint__builtin_nds32_mfsr(int``sr``)Return the content of a system register which is mapped by `sr`.

Built-in Functionint__builtin_nds32_mfusr(int``usr``)Return the content of a user space register which is mapped by `usr`.

Built-in Functionvoid__builtin_nds32_mtsr(int``value``,int``sr``)Move the `value` to a system register which is mapped by `sr`.

Built-in Functionvoid__builtin_nds32_mtusr(int``value``,int``usr``)Move the `value` to a user space register which is mapped by `usr`.

Built-in Functionvoid__builtin_nds32_setgie_en(void)Enable global interrupt.

Built-in Functionvoid__builtin_nds32_setgie_dis(void)Disable global interrupt.

GCC provides an interface to selected machine instructions from the picoChip instruction set.

`int __builtin_sbc (int`*value*)- Sign bit count. Return the number of consecutive bits in
`value`that have the same value as the sign bit. The result is the number of leading sign bits minus one, giving the number of redundant sign bits in`value`. `int __builtin_byteswap (int`*value*)- Byte swap. Return the result of swapping the upper and lower bytes of
`value`. `int __builtin_brev (int`*value*)- Bit reversal. Return the result of reversing the bits in
`value`. Bit 15 is swapped with bit 0, bit 14 is swapped with bit 1, and so on. `int __builtin_adds (int`*x*, int*y*)- Saturating addition. Return the result of adding
`x`and`y`, storing the value 32767 if the result overflows. `int __builtin_subs (int`*x*, int*y*)- Saturating subtraction. Return the result of subtracting
`y`from`x`, storing the value -32768 if the result overflows. `void __builtin_halt (void)`- Halt. The processor stops execution. This built-in is useful for implementing assertions.

These built-in functions are available for the PowerPC family of processors:

```
float __builtin_recipdivf (float, float);
float __builtin_rsqrtf (float);
double __builtin_recipdiv (double, double);
double __builtin_rsqrt (double);
uint64_t __builtin_ppc_get_timebase ();
unsigned long __builtin_ppc_mftb ();
double __builtin_unpack_longdouble (long double, int);
long double __builtin_pack_longdouble (double, double);
```

The `vec_rsqrt`, `__builtin_rsqrt`, and
`__builtin_rsqrtf` functions generate multiple instructions to
implement the reciprocal sqrt functionality using reciprocal sqrt
estimate instructions.

The `__builtin_recipdiv`, and `__builtin_recipdivf`
functions generate multiple instructions to implement division using
the reciprocal estimate instructions.

The `__builtin_ppc_get_timebase` and `__builtin_ppc_mftb`
functions generate instructions to read the Time Base Register. The
`__builtin_ppc_get_timebase` function may generate multiple
instructions and always returns the 64 bits of the Time Base Register.
The `__builtin_ppc_mftb` function always generates one instruction and
returns the Time Base Register value as an unsigned long, throwing away
the most significant word on 32-bit environments.

The following built-in functions are available for the PowerPC family
of processors, starting with ISA 2.06 or later (*-mcpu=power7*
or *-mpopcntd*):

```
long __builtin_bpermd (long, long);
int __builtin_divwe (int, int);
int __builtin_divweo (int, int);
unsigned int __builtin_divweu (unsigned int, unsigned int);
unsigned int __builtin_divweuo (unsigned int, unsigned int);
long __builtin_divde (long, long);
long __builtin_divdeo (long, long);
unsigned long __builtin_divdeu (unsigned long, unsigned long);
unsigned long __builtin_divdeuo (unsigned long, unsigned long);
unsigned int cdtbcd (unsigned int);
unsigned int cbcdtd (unsigned int);
unsigned int addg6s (unsigned int, unsigned int);
```

The `__builtin_divde`, `__builtin_divdeo`,
`__builtin_divdeu`, `__builtin_divdeou` functions require a
64-bit environment support ISA 2.06 or later.

The following built-in functions are available for the PowerPC family
of processors when hardware decimal floating point
(*-mhard-dfp*) is available:

```
_Decimal64 __builtin_dxex (_Decimal64);
_Decimal128 __builtin_dxexq (_Decimal128);
_Decimal64 __builtin_ddedpd (int, _Decimal64);
_Decimal128 __builtin_ddedpdq (int, _Decimal128);

unsigned long long __builtin_unpack_dec128 (_Decimal128, int);
_Decimal128 __builtin_pack_dec128 (unsigned long long, unsigned long long);
```

The following built-in functions are available for the PowerPC family of processors when the Vector Scalar (vsx) instruction set is available:

```
unsigned long long __builtin_unpack_vector_int128 (vector __int128_t, int);
vector __int128_t __builtin_pack_vector_int128 (unsigned long long,
unsigned long long);
```

GCC provides an interface for the PowerPC family of processors to access
the AltiVec operations described in Motorola’s AltiVec Programming
Interface Manual. The interface is made available by including
`<altivec.h>` and using *-maltivec* and
*-mabi=altivec*. The interface supports the following vector
types.

```
vector unsigned char
vector signed char
vector bool char
vector unsigned short
vector signed short
vector bool short
vector pixel
vector unsigned int
vector signed int
vector bool int
vector float
```

If *-mvsx* is used the following additional vector types are
implemented.

```
vector unsigned long
vector signed long
vector double
```

The long types are only implemented for 64-bit code generation, and the long type is only used in the floating point/integer conversion instructions.

GCC’s implementation of the high-level language interface available from C and C++ code differs from Motorola’s documentation in several ways.

A vector constant is a list of constant expressions within curly braces.

A vector initializer requires no cast if the vector constant is of the same type as the variable it is initializing.

If

`signed`or`unsigned`is omitted, the signedness of the vector type is the default signedness of the base type. The default varies depending on the operating system, so a portable program should always specify the signedness.Compiling with

*-maltivec*adds keywords`__vector`,`vector`,`__pixel`,`pixel`,`__bool`and`bool`. When compiling ISO C, the context-sensitive substitution of the keywords`vector`,`pixel`and`bool`is disabled. To use them, you must include`<altivec.h>`instead.GCC allows using a

`typedef`name as the type specifier for a vector type.For C, overloaded functions are implemented with macros so the following does not work:

vec_add ((vector signed int){1, 2, 3, 4}, foo);

Since

`vec_add`is a macro, the vector constant in the example is treated as four separate arguments. Wrap the entire argument in parentheses for this to work.

*Note:* Only the `<altivec.h>` interface is supported.
Internally, GCC uses built-in functions to achieve the functionality in
the aforementioned header file, but they are not supported and are
subject to change without notice.

The following interfaces are supported for the generic and specific AltiVec operations and the AltiVec predicates. In cases where there is a direct mapping between generic and specific operations, only the generic names are shown here, although the specific operations can also be used.

Arguments that are documented as `const int` require literal
integral values within the range required for that operation.

Note that the `vec_ld` and `vec_st` built-in functions always
generate the AltiVec `LVX` and `STVX` instructions even
if the VSX instruction set is available. The `vec_vsx_ld` and
`vec_vsx_st` built-in functions always generate the VSX `LXVD2X`,
`LXVW4X`, `STXVD2X`, and `STXVW4X` instructions.

If the ISA 2.07 additions to the vector/scalar (power8-vector)
instruction set is available, the following additional functions are
available for both 32-bit and 64-bit targets. For 64-bit targets, you
can use `vector long` instead of `vector long long`,
`vector bool long` instead of `vector bool long long`, and
`vector unsigned long` instead of `vector unsigned long long`.

If the ISA 2.07 additions to the vector/scalar (power8-vector)
instruction set is available, the following additional functions are
available for 64-bit targets. New vector types
(`vector __int128_t` and `vector __uint128_t`) are available
to hold the `__int128_t` and `__uint128_t` types to use these
builtins.

The normal vector extract, and set operations work on
`vector __int128_t` and `vector __uint128_t` types,
but the index value must be 0.

```
vector __int128_t vec_vaddcuq (vector __int128_t, vector __int128_t);

```

If the cryptographic instructions are enabled (*-mcrypto* or
*-mcpu=power8*), the following builtins are enabled.

```
vector unsigned long long __builtin_crypto_vsbox (vector unsigned long long);
vector unsigned long long __builtin_crypto_vcipher (vector unsigned long long,
vector unsigned long long);
vector unsigned long long __builtin_crypto_vcipherlast

vector unsigned long long __builtin_crypto_vncipherlast
(vector unsigned long long,

vector unsigned char __builtin_crypto_vpermxor (vector unsigned char,
vector unsigned char,
vector unsigned char);
vector unsigned short __builtin_crypto_vpermxor (vector unsigned short,

vector unsigned short);
vector unsigned int __builtin_crypto_vpermxor (vector unsigned int,
vector unsigned int,
vector unsigned int);
vector unsigned long long __builtin_crypto_vpermxor (vector unsigned long long,
vector unsigned long long,
vector unsigned long long);
vector unsigned char __builtin_crypto_vpmsumb (vector unsigned char,
vector unsigned char);
vector unsigned short __builtin_crypto_vpmsumb (vector unsigned short,
vector unsigned short);
vector unsigned int __builtin_crypto_vpmsumb (vector unsigned int,
vector unsigned int);
vector unsigned long long __builtin_crypto_vpmsumb (vector unsigned long long,
vector unsigned long long);
vector unsigned long long __builtin_crypto_vshasigmad
(vector unsigned long long, int, int);
vector unsigned int __builtin_crypto_vshasigmaw (vector unsigned int,
int, int);
```

The second argument to the `__builtin_crypto_vshasigmad` and
`__builtin_crypto_vshasigmaw` builtin functions must be a constant
integer that is 0 or 1. The third argument to these builtin functions
must be a constant integer in the range of 0 to 15.

GCC provides two interfaces for accessing the Hardware Transactional Memory (HTM) instructions available on some of the PowerPC family of processors (eg, POWER8). The two interfaces come in a low level interface, consisting of built-in functions specific to PowerPC and a higher level interface consisting of inline functions that are common between PowerPC and S/390.

The following low level built-in functions are available with
*-mhtm* or *-mcpu=CPU* where CPU is ‘power8’ or later.
They all generate the machine instruction that is part of the name.

The HTM builtins (with the exception of `__builtin_tbegin`) return
the full 4-bit condition register value set by their associated hardware
instruction. The header file `htmintrin.h` defines some macros that can
be used to decipher the return value. The `__builtin_tbegin` builtin
returns a simple true or false value depending on whether a transaction was
successfully started or not. The arguments of the builtins match exactly the
type and order of the associated hardware instruction’s operands, except for
the `__builtin_tcheck` builtin, which does not take any input arguments.
Refer to the ISA manual for a description of each instruction’s operands.

```
unsigned int __builtin_tbegin (unsigned int)
unsigned int __builtin_tend (unsigned int)
unsigned int __builtin_tabort (unsigned int)
unsigned int __builtin_tabortdc (unsigned int, unsigned int, unsigned int)
unsigned int __builtin_tabortdci (unsigned int, unsigned int, int)
unsigned int __builtin_tabortwc (unsigned int, unsigned int, unsigned int)
unsigned int __builtin_tabortwci (unsigned int, unsigned int, int)
unsigned int __builtin_tcheck (void)
unsigned int __builtin_treclaim (unsigned int)
unsigned int __builtin_trechkpt (void)
unsigned int __builtin_tsr (unsigned int)
```

In addition to the above HTM built-ins, we have added built-ins for some common extended mnemonics of the HTM instructions:

```
unsigned int __builtin_tendall (void)
unsigned int __builtin_tresume (void)
unsigned int __builtin_tsuspend (void)
```

The following set of built-in functions are available to gain access to the HTM specific special purpose registers.

```
unsigned long __builtin_get_texasr (void)
unsigned long __builtin_get_texasru (void)
unsigned long __builtin_get_tfhar (void)
unsigned long __builtin_get_tfiar (void)
void __builtin_set_texasr (unsigned long);
void __builtin_set_texasru (unsigned long);
void __builtin_set_tfhar (unsigned long);
void __builtin_set_tfiar (unsigned long);
```

Example usage of these low level built-in functions may look like:

```
#include <htmintrin.h>
int num_retries = 10;
while (1)
{
if (__builtin_tbegin (0))
{
/* Transaction State Initiated. */
if (is_locked (lock))
__builtin_tabort (0);
... transaction code...
__builtin_tend (0);
break;
}
else
{
/* Transaction State Failed. Use locks if the transaction
failure is "persistent" or we've tried too many times. */
if (num_retries-- <= 0
|| _TEXASRU_FAILURE_PERSISTENT (__builtin_get_texasru ()))
{
acquire_lock (lock);
... non transactional fallback path...
release_lock (lock);
break;
}
}
}
```

One final built-in function has been added that returns the value of
the 2-bit Transaction State field of the Machine Status Register (MSR)
as stored in `CR0`.

```
unsigned long __builtin_ttest (void)
```

This built-in can be used to determine the current transaction state using the following code example:

```
#include <htmintrin.h>
unsigned char tx_state = _HTM_STATE (__builtin_ttest ());
if (tx_state == _HTM_TRANSACTIONAL)
{
/* Code to use in transactional state. */
}
else if (tx_state == _HTM_NONTRANSACTIONAL)
{
/* Code to use in non-transactional state. */
}
else if (tx_state == _HTM_SUSPENDED)
{
/* Code to use in transaction suspended state. */
}
```

The following high level HTM interface is made available by including
`<htmxlintrin.h>` and using *-mhtm* or *-mcpu=CPU*
where CPU is ‘power8’ or later. This interface is common between PowerPC
and S/390, allowing users to write one HTM source implementation that
can be compiled and executed on either system.

```
long __TM_simple_begin (void)
long __TM_begin (void* const TM_buff)
long __TM_end (void)
void __TM_abort (void)
void __TM_named_abort (unsigned char const code)
void __TM_resume (void)
void __TM_suspend (void)
long __TM_is_user_abort (void* const TM_buff)
long __TM_is_named_user_abort (void* const TM_buff, unsigned char *code)
long __TM_is_illegal (void* const TM_buff)
long __TM_is_footprint_exceeded (void* const TM_buff)
long __TM_nesting_depth (void* const TM_buff)
long __TM_is_nested_too_deep(void* const TM_buff)
long __TM_is_conflict(void* const TM_buff)
long __TM_is_failure_persistent(void* const TM_buff)
long __TM_failure_address(void* const TM_buff)
long long __TM_failure_code(void* const TM_buff)
```

Using these common set of HTM inline functions, we can create a more portable version of the HTM example in the previous section that will work on either PowerPC or S/390:

```
#include <htmxlintrin.h>
int num_retries = 10;
TM_buff_type TM_buff;
while (1)
{
if (__TM_begin (TM_buff) == _HTM_TBEGIN_STARTED)
{
/* Transaction State Initiated. */
if (is_locked (lock))
__TM_abort ();
... transaction code...
__TM_end ();
break;
}
else

accumulator.

Built-in Functionvoid__builtin_rx_maclo(int,int)Generates the `maclo` machine instruction to add the result of
multiplying the bottom 16 bits of the two arguments into the
accumulator.

Built-in Functionvoid__builtin_rx_mulhi(int,int)Generates the `mulhi` machine instruction to place the result of
multiplying the top 16 bits of the two arguments into the
accumulator.

Built-in Functionvoid__builtin_rx_mullo(int,int)Generates the `mullo` machine instruction to place the result of
multiplying the bottom 16 bits of the two arguments into the
accumulator.

Built-in Functionint__builtin_rx_mvfachi(void)Generates the `mvfachi` machine instruction to read the top
32 bits of the accumulator.

Built-in Functionint__builtin_rx_mvfacmi(void)Generates the `mvfacmi` machine instruction to read the middle
32 bits of the accumulator.

Built-in Functionint__builtin_rx_mvfc(int)Generates the `mvfc` machine instruction which reads the control
register specified in its argument and returns its value.

Built-in Functionvoid__builtin_rx_mvtachi(int)Generates the `mvtachi` machine instruction to set the top
32 bits of the accumulator.

Built-in Functionvoid__builtin_rx_mvtaclo(int)Generates the `mvtaclo` machine instruction to set the bottom
32 bits of the accumulator.

Built-in Functionvoid__builtin_rx_mvtc(intreg,intval)Generates the `mvtc` machine instruction which sets control
register number `reg` to `val`.

Built-in Functionvoid__builtin_rx_mvtipl(int)Generates the `mvtipl` machine instruction set the interrupt
priority level.

Built-in Functionvoid__builtin_rx_racw(int)Generates the `racw` machine instruction to round the accumulator
according to the specified mode.

Built-in Functionint__builtin_rx_revw(int)Generates the `revw` machine instruction which swaps the bytes in
the argument so that bits 0-7 now occupy bits 8-15 and vice versa,
and also bits 16-23 occupy bits 24-31 and vice versa.

Built-in Functionvoid__builtin_rx_rmpa(void)Generates the `rmpa` machine instruction which initiates a
repeated multiply and accumulate sequence.

Built-in Functionvoid__builtin_rx_round(float)Generates the `round` machine instruction which returns the
floating-point argument rounded according to the current rounding mode
set in the floating-point status word register.

Built-in Functionint__builtin_rx_sat(int)Generates the `sat` machine instruction which returns the
saturated value of the argument.

Built-in Functionvoid__builtin_rx_setpsw(int)Generates the `setpsw` machine instruction to set the specified
bit in the processor status word.

Built-in Functionvoid__builtin_rx_wait(void)Generates the `wait` machine instruction.

Built-in Functionint__builtin_tbegin(void*)Generates the `tbegin` machine instruction starting a
non-constraint hardware transaction. If the parameter is non-NULL the
memory area is used to store the transaction diagnostic buffer and
will be passed as first operand to `tbegin`. This buffer can be
defined using the `struct __htm_tdb` C struct defined in
`htmintrin.h` and must reside on a double-word boundary. The
second tbegin operand is set to `0xff0c`. This enables
save/restore of all GPRs and disables aborts for FPR and AR
manipulations inside the transaction body. The condition code set by
the tbegin instruction is returned as integer value. The tbegin
instruction by definition overwrites the content of all FPRs. The
compiler will generate code which saves and restores the FPRs. For
soft-float code it is recommended to used the `*_nofloat`
variant. In order to prevent a TDB from being written it is required
to pass an constant zero value as parameter. Passing the zero value
through a variable is not sufficient. Although modifications of
access registers inside the transaction will not trigger an
transaction abort it is not supported to actually modify them. Access
registers do not get saved when entering a transaction. They will have
undefined state when reaching the abort code.

Macros for the possible return codes of tbegin are defined in the
`htmintrin.h` header file:

`_HTM_TBEGIN_STARTED``tbegin`has been executed as part of normal processing. The transaction body is supposed to be executed.`_HTM_TBEGIN_INDETERMINATE`- The transaction was aborted due to an indeterminate condition which might be persistent.
`_HTM_TBEGIN_TRANSIENT`- The transaction aborted due to a transient failure. The transaction should be re-executed in that case.
`_HTM_TBEGIN_PERSISTENT`- The transaction aborted due to a persistent failure. Re-execution under same circumstances will not be productive.

Macro_HTM_FIRST_USER_ABORT_CODEThe `_HTM_FIRST_USER_ABORT_CODE` defined in `htmintrin.h`
specifies the first abort code which can be used for
`__builtin_tabort`. Values below this threshold are reserved for
machine use.

Data typestruct __htm_tdbThe `struct __htm_tdb` defined in `htmintrin.h` describes
the structure of the transaction diagnostic block as specified in the
Principles of Operation manual chapter 5-91.

Built-in Functionint__builtin_tbegin_nofloat(void*)Same as `__builtin_tbegin` but without FPR saves and restores.
Using this variant in code making use of FPRs will leave the FPRs in
undefined state when entering the transaction abort handler code.

Built-in Functionint__builtin_tbegin_retry(void*,int)In addition to `__builtin_tbegin` a loop for transient failures
is generated. If tbegin returns a condition code of 2 the transaction
will be retried as often as specified in the second argument. The
perform processor assist instruction is used to tell the CPU about the
number of fails so far.

Built-in Functionint__builtin_tbegin_retry_nofloat(void*,int)Same as `__builtin_tbegin_retry` but without FPR saves and
restores. Using this variant in code making use of FPRs will leave
the FPRs in undefined state when entering the transaction abort
handler code.

Built-in Functionvoid__builtin_tbeginc(void)Generates the `tbeginc` machine instruction starting a constraint
hardware transaction. The second operand is set to `0xff08`.

Built-in Functionint__builtin_tend(void)Generates the `tend` machine instruction finishing a transaction
and making the changes visible to other threads. The condition code
generated by tend is returned as integer value.

Built-in Functionvoid__builtin_tabort(int)Generates the `tabort` machine instruction with the specified
abort code. Abort codes from 0 through 255 are reserved and will
result in an error message.

Built-in Functionvoid__builtin_tx_assist(int)Generates the `ppa rX,rY,1` machine instruction. Where the
integer parameter is loaded into rX and a value of zero is loaded into
rY. The integer parameter specifies the number of times the
transaction repeatedly aborted.

Built-in Functionint__builtin_tx_nesting_depth(void)Generates the `etnd` machine instruction. The current nesting
depth is returned as integer value. For a nesting depth of 0 the code
is not executed as part of an transaction.

Built-in Functionvoid__builtin_non_tx_store(uint64_t*,uint64_t)Generates the `ntstg` machine instruction. The second argument
is written to the first arguments location. The store operation will
not be rolled-back in case of an transaction abort.

The following built-in functions are supported on the SH1, SH2, SH3 and SH4 families of processors:

Built-in Functionvoid__builtin_set_thread_pointer(void*``ptr``)Sets the `GBR` register to the specified value `ptr`. This is usually
used by system code that manages threads and execution contexts. The compiler
normally does not generate code that modifies the contents of `GBR` and
thus the value is preserved across function calls. Changing the `GBR`
value in user code must be done with caution, since the compiler might use
`GBR` in order to access thread local variables.

Built-in Functionvoid *__builtin_thread_pointer(void)Returns the value that is currently set in the `GBR` register.
Memory loads and stores that use the thread pointer as a base address are
turned into `GBR` based displacement loads and stores, if possible.
For example:

```
struct my_tcb
{
int a, b, c, d, e;
};
int get_tcb_value (void)
{
// Generate :samp:`mov.l @(8,gbr),r0` instruction
return ((my_tcb*)__builtin_thread_pointer ())->c;
}
```

Built-in Functionunsigned int__builtin_sh_get_fpscr(void)Returns the value that is currently set in the `FPSCR` register.

Built-in Functionvoid__builtin_sh_set_fpscr(unsignedint``val``)Sets the `FPSCR` register to the specified value `val`, while
preserving the current values of the FR, SZ and PR bits.

GCC provides extensions for the SPU processor as described in the Sony/Toshiba/IBM SPU Language Extensions Specification, which can be found at http://cell.scei.co.jp/ or http://www.ibm.com/developerworks/power/cell/. GCC’s implementation differs in several ways.

The optional extension of specifying vector constants in parentheses is not supported.

A vector initializer requires no cast if the vector constant is of the same type as the variable it is initializing.

If

`signed`or`unsigned`is omitted, the signedness of the vector type is the default signedness of the base type. The default varies depending on the operating system, so a portable program should always specify the signedness.By default, the keyword

`__vector`is added. The macro`vector`is defined in`<spu_intrinsics.h>`and can be undefined.GCC allows using a

`typedef`name as the type specifier for a vector type.For C, overloaded functions are implemented with macros so the following does not work:

spu_add ((vector signed int){1, 2, 3, 4}, foo);

Since

`spu_add`is a macro, the vector constant in the example is treated as four separate arguments. Wrap the entire argument in parentheses for this to work.The extended version of

`__builtin_expect`is not supported.

*Note:* Only the interface described in the aforementioned
specification is supported. Internally, GCC uses built-in functions to
implement the required functionality, but these are not supported and
are subject to change without notice.

GCC provides intrinsics to access certain instructions of the TI C6X
processors. These intrinsics, listed below, are available after
inclusion of the `c6x_intrinsics.h` header file. They map directly
to C6X instructions.

```
int _sadd (int, int)
int _ssub (int, int)
int _sadd2 (int, int)
int _ssub2 (int, int)
long long _mpy2 (int, int)
long long _smpy2 (int, int)
int _add4 (int, int)
int _sub4 (int, int)
int _saddu4 (int, int)
int _smpy (int, int)
int _smpyh (int, int)
int _smpyhl (int, int)
int _smpylh (int, int)
int _sshl (int, int)
int _subc (int, int)
int _avg2 (int, int)
int _avgu4 (int, int)
int _clrr (int, int)
int _extr (int, int)
int _extru (int, int)
int _abs (int)
int _abs2 (int)
```

GCC provides intrinsics to access every instruction of the TILE-Gx processor. The intrinsics are of the form:

`unsigned long long __insn_``op`` (...)`

Where `op` is the name of the instruction. Refer to the ISA manual
for the complete list of instructions.

GCC also provides intrinsics to directly access the network registers. The intrinsics are:

```
unsigned long long __tile_idn0_receive (void)
unsigned long long __tile_idn1_receive (void)
unsigned long long __tile_udn0_receive (void)
unsigned long long __tile_udn1_receive (void)
unsigned long long __tile_udn2_receive (void)
unsigned long long __tile_udn3_receive (void)
void __tile_idn_send (unsigned long long)
void __tile_udn_send (unsigned long long)
```

The intrinsic `void __tile_network_barrier (void)` is used to
guarantee that no network operations before it are reordered with
those after it.

GCC provides intrinsics to access every instruction of the TILEPro processor. The intrinsics are of the form:

`unsigned __insn_``op`` (...)`

where `op` is the name of the instruction. Refer to the ISA manual
for the complete list of instructions.

GCC also provides intrinsics to directly access the network registers. The intrinsics are:

```
unsigned __tile_idn0_receive (void)
unsigned __tile_idn1_receive (void)
unsigned __tile_sn_receive (void)
unsigned __tile_udn0_receive (void)
unsigned __tile_udn1_receive (void)
unsigned __tile_udn2_receive (void)
unsigned __tile_udn3_receive (void)
void __tile_idn_send (unsigned)
void __tile_sn_send (unsigned)
void __tile_udn_send (unsigned)
```

The intrinsic `void __tile_network_barrier (void)` is used to
guarantee that no network operations before it are reordered with
those after it.

These built-in functions are available for the x86-32 and x86-64 family of computers, depending on the command-line switches used.

If you specify command-line switches such as *-msse*,
the compiler could use the extended instruction sets even if the built-ins
are not used explicitly in the program. For this reason, applications
that perform run-time CPU detection must compile separate files for each
supported architecture, using the appropriate flags. In particular,
the file containing the CPU detection code should be compiled without
these options.

The following machine modes are available for use with MMX built-in functions
(see *Using Vector Instructions through Built-in Functions*): `V2SI` for a vector of two 32-bit integers,
`V4HI` for a vector of four 16-bit integers, and `V8QI` for a
vector of eight 8-bit integers. Some of the built-in functions operate on
MMX registers as a whole 64-bit entity, these use `V1DI` as their mode.

If 3DNow! extensions are enabled, `V2SF` is used as a mode for a vector
of two 32-bit floating-point values.

If SSE extensions are enabled, `V4SF` is used for a vector of four 32-bit
floating-point values. Some instructions use a vector of four 32-bit
integers, these use `V4SI`. Finally, some instructions operate on an
entire vector register, interpreting it as a 128-bit integer, these use mode
`TI`.

In 64-bit mode, the x86-64 family of processors uses additional built-in
functions for efficient use of `TF` (`__float128`) 128-bit
floating point and `TC` 128-bit complex floating-point values.

The following floating-point built-in functions are available in 64-bit mode. All of them implement the function that is part of the name.

```
__float128 __builtin_fabsq (__float128)
__float128 __builtin_copysignq (__float128, __float128)
```

The following built-in function is always available.

`void __builtin_ia32_pause (void)`Generates the

`pause`machine instruction with a compiler memory barrier.The following floating-point built-in functions are made available in the

64-bit mode.

`__float128 __builtin_infq (void)`- Similar to
`__builtin_inf`, except the return type is`__float128`. `__float128 __builtin_huge_valq (void)`Similar to

`__builtin_huge_val`, except the return type is`__float128`.The following built-in functions are always available and can be used to

check the target platform type.

Built-in Functionvoid__builtin_cpu_init(void)This function runs the CPU detection code to check the type of CPU and the
features supported. This built-in function needs to be invoked along with the built-in functions
to check CPU type and features, `__builtin_cpu_is` and
`__builtin_cpu_supports`, only when used in a function that is
executed before any constructors are called. The CPU detection code is
automatically executed in a very high priority constructor.

For example, this function has to be used in `ifunc` resolvers that
check for CPU type using the built-in functions `__builtin_cpu_is`
and `__builtin_cpu_supports`, or in constructors on targets that
don’t support constructor priority.

```
static void (*resolve_memcpy (void)) (void)
{
// ifunc resolvers fire before constructors, explicitly call the init
// function.
__builtin_cpu_init ();
if (__builtin_cpu_supports ("ssse3"))
return ssse3_memcpy; // super fast memcpy with ssse3 instructions.
else
return default_memcpy;
}
void *memcpy (void *, const void *, size_t)
__attribute__ ((ifunc ("resolve_memcpy")));
```

Built-in Functionint__builtin_cpu_is(constchar*``cpuname``)This function returns a positive integer if the run-time CPU
is of type `cpuname`
and returns `0` otherwise. The following CPU names can be detected:

`intel`- Intel CPU.
`atom`- Intel Atom CPU.
`core2`- Intel Core 2 CPU.
`corei7`- Intel Core i7 CPU.
`nehalem`- Intel Core i7 Nehalem CPU.
`westmere`- Intel Core i7 Westmere CPU.
`sandybridge`- Intel Core i7 Sandy Bridge CPU.
`amd`- AMD CPU.
`amdfam10h`- AMD Family 10h CPU.
`barcelona`- AMD Family 10h Barcelona CPU.
`shanghai`- AMD Family 10h Shanghai CPU.
`istanbul`- AMD Family 10h Istanbul CPU.
`btver1`- AMD Family 14h CPU.
`amdfam15h`- AMD Family 15h CPU.
`bdver1`- AMD Family 15h Bulldozer version 1.
`bdver2`- AMD Family 15h Bulldozer version 2.
`bdver3`- AMD Family 15h Bulldozer version 3.
`bdver4`- AMD Family 15h Bulldozer version 4.
`btver2`AMD Family 16h CPU.

Here is an example:

```
if (__builtin_cpu_is ("corei7"))
{
do_corei7 (); // Core i7 specific implementation.
}
else
{
do_generic (); // Generic implementation.
}
```

Built-in Functionint__builtin_cpu_supports(constchar*``feature``)This function returns a positive integer if the run-time CPU
supports `feature`
and returns `0` otherwise. The following features can be detected:

`cmov`- CMOV instruction.
`mmx`- MMX instructions.
`popcnt`- POPCNT instruction.
`sse`- SSE instructions.
`sse2`- SSE2 instructions.
`sse3`- SSE3 instructions.
`ssse3`- SSSE3 instructions.
`sse4.1`- SSE4.1 instructions.
`sse4.2`- SSE4.2 instructions.
`avx`- AVX instructions.
`avx2`- AVX2 instructions.
`avx512f`AVX512F instructions.

Here is an example:

```
if (__builtin_cpu_supports ("popcnt"))
{
asm("popcnt %1,%0" : "=r"(count) : "rm"(n) : "cc");
}
else
{
count = generic_countbits (n); //generic implementation.
}
```

The following built-in functions are made available by *-mmmx*.
All of them generate the machine instruction that is part of the name.
