Summary: ICE in calls.c:3141 / assert after emit_stack_restore
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: uweigand@gcc.gnu.org
CC: rth@gcc.gnu.org
Target: spu-elf
I'm seeing ICEs in calls.c:3141 on spu-elf after this patch went in:
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg00075.html
One test case showing this problem is:
gcc.c-torture/compile/20030224-1.c
The problem here is that SPU's restore_stack_block generates insn
sequences that do not terminate in a SET of stack_pointer_rtx,
see this for further discussion:

Tests have completed now; the patch fixes all regressions introduced by the
original commit, and introduced no new ones. Looks good to me.
