commit 7af7e92f6be0b65237900ac479e17970daa5faf0
Author: Martin Liska <mliska@suse.cz>
Date: Thu Oct 14 14:57:18 2021 +0200
options: Fix variable tracking option processing.
PR debug/102585
PR bootstrap/102766
gcc/ChangeLog:
* opts.c (finish_options): Process flag_var_tracking* options
here as they can be adjusted by optimize attribute.
* toplev.c (process_options): Remove it here.
* common.opt: Make debug_nonbind_markers_p as PerFunction
attribute as it depends on optimization level.
gcc/testsuite/ChangeLog:
* gcc.dg/pr102585.c: New test.
