Subject: Handle a location with NULL as a file (PR driver/90495)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=804424b95b112cd334ae29d942351e4c4e24ba94;p=gcc.git

Handle a location with NULL as a file (PR driver/90495)

2019-05-17  Martin Liska  <mliska@suse.cz>

	PR driver/90495
	* toplev.c (output_stack_usage): With LTO and sanitizer it
	happens that a global ctor (_GLOBAL__sub_I_00099_0_main)
	has no file location.
