Bug #: 51536
Summary: ICE on mips64 with -march=octeon -O2 -g
-fno-omit-frame-pointer
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: pinskia@gcc.gnu.org
t.c: In function 'can_migrate_task':
t.c:11:1: internal compiler error: in maybe_record_trace_start, at
dwarf2cfi.c:2244
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
--- CUT ---
int can_migrate_task(int *p, int *sd)
{
int tsk_cache_hot;
if (p[1] == 5)
tsk_cache_hot = 1;
else
tsk_cache_hot = p[0] < 500000ULL;
if (!tsk_cache_hot || *sd > 1)
return 1;
return 0;
}
--- CUT ---
Branch delay slot is putting:
(insn/f 52 10 11 (set (reg/f:DI 30 $fp)
(reg/f:DI 29 $sp)) 276 {*movdi_64bit}
(nil))
Which causes the ICE. This is related to PR 51471 but slightly different.

The patch which I am working on for PR 51471 will also fix this one. Closing
as a dup.
