Bug ID: 115688
Summary: ICE on simple test case from r15-703-gb390b011569635
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: bergner at gcc dot gnu.org
Target Milestone: ---
After r15-703-gb390b011569635, we're seeing test case pr111380-2.c ICE on
32-bit BE compiles. It hits the new gcc_assert from the commit above. The
failure looks like (ICEs for power4/5/6 and does not ICE for power7 and later):
bergner@nilram:ICE$ cat ice.c
long __attribute__ ((target ("vsx")))
foo (void)
{
return 0;
}
bergner@nilram:ICE$ gcc -S -m32 -O2 -mcpu=power5 -mno-vsx ice.c
