Bug ID: 96787
Summary: rs6000 mcpu=power10 miscompiles libiberty
htab_delete() causing bootstrap failure
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target

hashtab.c with no added attributes
Building r11-2827 configured using --with-cpu=power10, I am seeing some kind of
compile failure in libiberty hashtab.o function htab_delete(). Putting
__attribute__ ((target("cpu=power9")) in front of that function clears the
problem.
The manifestation is that genmddeps segfaults.
I've attached asm output with (.fixed.s) and without (.broken.s) the attribute
on htab_delete().
