Bug ID: 104705
Summary: [12 regression] ICE ‘global_options’ are modified in
local context in cl_optimization_compare
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: slyfox at gcc dot gnu.org
CC: mliska at suse dot cz
Target Milestone: ---
Tried to build ghc-HEAD with gcc-master today, got an ICE on pragmas in
intrisics.
Here is a small reproducer (I think I lost real "optimize" value during
shrinking, does it matter much for this ICE?):
//$ cat a.c
#pragma GCC optimize "foo"
#pragma GCC push_options
#pragma GCC pop_options
$ /tmp/bg/gcc/xgcc -B/tmp/bg/gcc -c a.c -O2 -Wall
a.c:1:9: warning: bad option ‘-ffoo’ to pragma ‘optimize’ [-Wpragmas]
1 | #pragma GCC optimize "foo"
| ^~~
a.c:3:9: internal compiler error: ‘global_options’ are modified in local
context
3 | #pragma GCC pop_options
| ^~~
