void dwarf2out_begin_prologue	(	unsigned int	line,
		const char *	file
	)

Dwarf2 frame information.

Output a marker (i.e. a label) for the beginning of a function, before the prologue.

 ??? current_function_func_begin_label is also used by except.c for
 call-site information.  We must emit this label if it might be used.

 We can elide the fde allocation if we're not emitting debug info.

 Cater to the various TARGET_ASM_OUTPUT_MI_THUNK implementations that
 emit insns as rtx but bypass the bulk of rest_of_compilation, which
 would include pass_dwarf2_frame.  If we've not created the FDE yet,
 do so now.

 Initialize the bits of CURRENT_FDE that were not available earlier.

 We only want to output line number information for the genuine dwarf2
 prologue case, not the eh frame case.

     We cannot keep a current personality per function as without CFI
     asm, at the point where we emit the CFI data, there is no current
     function anymore.

bool dwarf2out_do_cfi_asm ( void )

Decide whether to emit frame unwind via assembler directives.

 Assume failure for a moment.

 Make sure the personality encoding is one the assembler can support.
 In particular, aligned addresses can't be handled.

 If we can't get the assembler to emit only .debug_frame, and we don't need
 dwarf2 unwind info for exceptions, then emit .debug_frame by hand.

 Success!

bool dwarf2out_do_frame ( void )

Decide whether we want to emit frame unwind information for the current translation unit.

We want to emit correct CFA location expressions or lists, so we have to return true if we're going to output debug info, even if we're not going to output frame or unwind info.

void dwarf2out_end_epilogue	(	unsigned int	line,
		const char *	file
	)

Output a marker (i.e. a label) for the absolute end of the generated code for a function definition. This gets called after the epilogue code has been generated.

Output a label to mark the endpoint of the code generated for this function.

Referenced by output_loc_sequence_raw().

void dwarf2out_frame_finish ( void )

Output call frame information.

 Output another copy for the unwinder.

void dwarf2out_switch_text_section ( void )

There is no need to mark used sections when not debugging.

 Now do the real section switch.

void dwarf2out_vms_begin_epilogue	(	unsigned int	line,
		const char *	file
	)

Output a marker (i.e. a label) for the beginning of the generated code for a function epilogue. This gets called before the prologue code has been generated.

Output a label to mark the endpoint of the code generated for this function.
