X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4d1065ed1b3ec80edaa39bcb1b302b7cc0d1f2cb;p=gcc.git

varasm.c (function_section): New function.

	* varasm.c (function_section): New function.
	(assemble_start_function): Call it.
	* output.h (function_section): Declare it.
	* final.c (final_scan_insn): Call function_section instead of
	text_section.
	* dwarfout.c (dwarfout_begin_block): Likewise.
	(dwarfout_end_block): Likewise.
	(dwarfout_label): Likewise.
	(dwarfout_begin_function): Likewise.
	(dwarfout_end_function): Likewise.
	(dwarfout_line): Likewise.
