Bug ID: 108910
Summary: [13 Regression] Further ICE in aarch64_layout_arg
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
extern void foo (float, float *, float *);
void
bar (void *p)
{
float *__attribute__((aligned (64))) q = __builtin_assume_aligned (p, 64);
foo (0.0f, q, q);
}
ICEs on aarch64-linux with -O2 likely since r13-5124 with:
during RTL pass: expand
woohoo.c: In function ‘bar’:
woohoo.c:7:3: internal compiler error: in aarch64_layout_arg, at
config/aarch64/aarch64.cc:7688

I know trying to overalign a pointer type (rather than what it points to) is
very dumb,
but some real-world code (most likely just by mistake (but many)) does that:
