| typedef bool(* noswitch_section_callback)(tree decl, const char *name, unsigned HOST_WIDE_INT size, unsigned HOST_WIDE_INT rounded) |
A callback that writes the assembly code for a decl in a SECTION_NOSWITCH section. DECL is the decl that should be assembled and NAME is the name of its SYMBOL_REF. SIZE is the size of the decl in bytes and ROUNDED is that size rounded up to the next BIGGEST_ALIGNMENT / BITS_PER_UNIT boundary. Return true if the callback used DECL_ALIGN to set the object's alignment. A false return value implies that we are relying on the rounded size to align the decl.
| typedef void(* unnamed_section_callback)(const void *) |
A callback that writes the assembly code for switching to an unnamed section. The argument provides callback-specific data.
| enum section_category |
A helper function for default_elf_select_section and default_elf_unique_section. Categorizes the DECL.
| void align_variable | ( | tree | decl, |
| bool | dont_output_data | ||
| ) |
Compute the alignment of variable specified by DECL. DONT_OUTPUT_DATA is from assemble_variable.

Should not be called for variables of incomplete structure type. TOP_LEVEL is nonzero if this variable has file scope. AT_END is nonzero if this is the special handling, at end of compilation, to define things that have had only tentative definitions. DONT_OUTPUT_DATA if nonzero means don't actually output the initial value (that will be done by the caller).

Emit a special section directive to indicate that this object file was compiled with -fsplit-stack. This is used to let the linker detect calls between split-stack code and non-split-stack code, so that it can modify the split-stack code to allocate a sufficiently large stack. We emit another special section if there are any functions in this file which have the no_split_stack attribute, to prevent the linker from warning about being unable to convert the functions if they call non-split-stack code.

| int only_leaf_regs_used | ( | void | ) |
Return 1 if this function uses only the registers that can be safely renumbered.
On some machines, a function with no call insns can run faster if it doesn't create its own register window. When output, the leaf function should use only the "output" registers. Ordinarily, the function would be compiled to use the "input" registers to find its arguments; it is a candidate for leaf treatment if it uses only the "input" registers. Leaf function treatment means renumbering so the function uses the "output" registers instead.
Return 1 if this function uses only the registers that can be safely renumbered.
