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.

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.

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