Bug ID: 84264
Summary: ICE in rs6000_emit_le_vsx_store, at
config/rs6000/rs6000.c:10367
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: segher at gcc dot gnu.org, wschmidt at gcc dot gnu.org
Target Milestone: ---
Following code snippet ICEs:
$ cat ice.ii
void _setjmp ();
void a (unsigned long *);
void
b ()
{
for (;;)
{
_setjmp ();
unsigned long args[9]{};
a (args);
}
}
$ ./xgcc -B. ice.ii -O1 -fstack-protector-strong -c
during RTL pass: reload
ice.ii: In function ‘void b()’:
ice.ii:12:1: internal compiler error: in rs6000_emit_le_vsx_store, at
config/rs6000/rs6000.c:10367
