------- Comment #11 from jakub at gcc dot gnu dot org 2010-04-19 07:02 -------
This change broke building wine on x86-64. Distilled testcase:
__attribute__ ((ms_abi)) fn2 (int, int);
struct S { int s; };
struct T { int t; struct S *u; };
void
foo (struct T *x, void *y)
{
int a, b, c, d;
fn1 (0, &a, &b, &c, &d);
x->u[x->t].s = fn2 (fn3 (), a);
fn1 (y, &a, &b, &c, &d);
}
__attribute__ ((ms_abi)) void
bar (int x)
{
}
void
baz (int x)
{
}
now ICEs at -O2 on x86_64-linux with:
wineice.i: In function 'foo':
wineice.i:12: internal compiler error: in insert_save, at caller-save.c:1171
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Apparently setup_save_areas
saved_reg->slot
= assign_stack_local_1
(regno_save_mode[regno][1],
GET_MODE_SIZE (regno_save_mode[regno][1]), 0, true);
creates a slot where regno_save_mode[regno][1] for regno 4 is VOIDmode, and the
VOIDmode MEM which has MEM_ALIGN 0 then confuses everything.

There was already a bug filed for this and a patch was committed today
or yesterday to the trunk to fix this ice.
