Bug ID: 127023
Summary: [16/17 regression] ICE when building darktable
(redirect_callee, at cgraph.cc:1712)
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
CC: jamborm at gcc dot gnu.org
Target Milestone: ---
Noticed this by chance. Apparently Arch hit this at
https://gitlab.archlinux.org/archlinux/packaging/packages/gcc/-/work_items/46
but it's unfortunate nobody brought it here.
In the bug, they've bisected for the fix on trunk and said
r17-646-g2508fac25d2722 fixes it, so latent. 16 ICEs though.
```
typedef int a;
typedef enum { b, c } d;
__attribute__((target_clones("default", "fma4"))) void
e(float *, float *, a, a, d f, float, float, float) {
switch (f)
case b:
#pragma omp parallel
for (;;)
;
}
__attribute__((target_clones("default", "fma4"))) void g(float *h, float *i) {
a j;
a height;
e(h, i, j, height, c, 1.0f, 0.0f, 1.0f);
}
```
```
