Bug ID: 104327
Summary: [12 Regression] Inlining error on s390x since r12-1039
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
Since r12-1039-gebd5e86c0f41dc1d692f9b2b68a510b1f6835a3e
we reject following testcase on s390x-linux (reduced from php):
void foo (int *);
static inline __attribute__((always_inline)) void
bar (int *x)
{
foo (x);
}
__attribute__((cold, optimize("Os"))) void
baz (int *x)
{
bar (x);
}
(with -O0 or -O2 etc.):
rh2048565.c: In function ‘baz’:
rh2048565.c:4:1: error: inlining failed in call to ‘always_inline’ ‘bar’:
target specific option mismatch
4 | bar (int *x)
| ^~~
rh2048565.c:12:3: note: called from here
12 | bar (x);
| ^~~~~~~
target attribute isn't used at all though. Seems the mismatch is because the
r12-1039 code sets DECL_FUNCTION_SPECIFIC_TARGET on the baz caller to non-NULL,
while bar has it NULL.
