| const char* function::cannot_be_copied_reason |
Non-null if the function does something that would prevent it from
being copied; this applies to both versioning and inlining. Set to
a string describing the reason for failure.
| unsigned int function::cannot_be_copied_set |
Nonzero if we've set cannot_be_copied_reason. I.e. if
(cannot_be_copied_set && !cannot_be_copied_reason), the function
can in fact be copied.
| struct control_flow_graph* function::cfg |
The control flow graph for this function.
Referenced by gimple_call_arg_flags(), and replace_ssa_name().
| tree function::cilk_frame_decl |
In a Cilk function, the VAR_DECL for the frame descriptor.
| unsigned int function::curr_properties |
Properties used by the pass manager.
Referenced by copy_decl_maybe_to_var(), and verify_curr_properties().
| tree function::decl |
For function.c.
Points to the FUNCTION_DECL of this function.

used for unwinding. Only set when either dwarf2 unwinding or dwarf2
debugging is enabled.

| unsigned int function::has_force_vect_loops |
Nonzero if the current function contains any loops with
loop->force_vect set.
Referenced by tree_loop_vectorize().
| unsigned int function::has_local_explicit_reg_vars |
Nonzero if this function has local DECL_HARD_REGISTER variables.
In this case code motion has to be done more carefully.
| unsigned int function::has_nonlocal_label |
Nonzero if function being compiled receives nonlocal gotos
from nested functions.

nonzero value in loop->simduid.
Referenced by vectorize_loops().
| unsigned int function::is_cilk_function |
This will indicate whether a function is a cilk function
Referenced by get_frame_arg().
| unsigned int function::is_thunk |
Nonzero if the current function is a thunk, i.e., a lightweight
function implemented by the output_mi_thunk hook) that just
adjusts one of its arguments and forwards to another
function.
Referenced by default_ctor_section_asm_out_constructor(), and profile_function().
| struct language_function* function::language |
Language-specific code can use this to store whatever it likes.
| int function::last_stmt_uid |
Last statement uid.
| unsigned int function::last_verified |
Vector of function local variables, functions, types and constants.
| struct machine_function* function::machine |
For md files.
tm.h can use this to store whatever it likes.
| tree function::nonlocal_goto_save_area |
An expression that contains the non-local goto save area. The first
word is the saved frame pointer and the second is the saved stack
pointer.

return the address of where it has put a structure value.
Referenced by copy_decl_no_change(), and set_cfun().
| unsigned int function::returns_struct |
Fields below this point are not set for abstract functions; see
allocate_struct_function. Nonzero if function being compiled needs to be given an address
where the value should be stored.

Number of units of floating point registers that need saving in stdarg
function.
| unsigned int function::va_list_gpr_size |
Collected bit flags.
Number of units of general registers that need saving in stdarg
function. What unit is depends on the backend, either it is number
of bytes, or it can be number of registers.
| htab_t function::value_histograms |
Value histograms attached to particular statements.
| struct loops* function::x_current_loops |
The loops in this function.
