Bug #: 56451
Summary: [4.8 regression] Wrong code for
gcc.c-torture/execute/941015-1.c on SH
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: rtl-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: kkojima@gcc.gnu.org
Target: sh*-*-*
On sh4-linux, the function foo1 of gcc.c-torture/execute/941015-1.c
int
foo1 (value)
long long value;
{
register const long long constant = 0xc000000080000000LL;
if (value < constant)
return 1;
else
return 2;
}
is assembled to a wrong code with -O1
foo1:
mov.l .L7,r1
cmp/gt r1,r5
bt/s .L10
mov #2,r0
cmp/ge r1,r5
bf/s .L10
mov #1,r0
.L10:
rts
nop
.L9:
.align 2
.L7:
.long -1073741824
It looks delayed branch optimization causes this.

--- Comment #1 from Kazumoto Kojima <kkojima at gcc dot gnu.org> 2013-02-26 00:32:07 UTC ---
Before dbr_schedule, the insns look like:
r1 := 0xc0000000
(A) if (r5 > r1) goto L0
(B) if (r5 < r1) goto L1
r1 := 0x80000000
(C) if (r4 >= r1) goto L0
L1: r0 := 1
goto L2
L0: r0 := 2
L2:
On SH, insns (A),(B),(C) can have delayed slot. dbr_schedule fills
a slot of (A) first:
r1 := 0xc0000000
(A) [if (r5 > r1) goto L2 | r0 := 2]
(B) if (r5 < r1) goto L1
r1 := 0x80000000
(C) if (r4 >= r1) goto L0
L1: r0 := 1
goto L2
L0: r0 := 2
L2:
Curiously, in the problematic case, dbr_schedule tries (C) next and
redundant_insn checks that r0 := 2 is whether redundant or not with
scanning insns backward from (C). It finds the insn in the slot of
(A) and deletes the insn r0 := 2 at L0 as an unnecessary one.
r1 := 0xc0000000
(A) [if (r5 > r1) goto L2 | r0 := 2]
(B) if (r5 < r1) goto L1
r1 := 0x80000000
(C) if (r4 >= r1) goto L0
L1: r0 := 1
goto L2
L0:
L2:
Then dbr_schedule fills the slot of (B):
r1 := 0xc0000000
(A) [if (r5 > r1) goto L2 | r0 := 2]
(B) [if (r5 < r1) goto L2 | r0 := 1]
r1 := 0x80000000
(C) if (r4 >= r1) goto L0
L1: r0 := 1
goto L2
L0:
L2:
Now (C) and r0 := 1 at L1 are useless because r0 is 1 before (C).
It seems to me that the above is an unexpected scenario to redundant_insn,
i.e. dbr_schedule uses it unsafely somewhere, though I gave up to find
where problematic use occurs. An easy patch below might be a bit
overkill but it fixes the problem for me.

I didn't follow it, but it looks related.

Hm, I'm just poking around here, sorry if it's just useless noise ...
In dbr_schedule, doing:
fill_simple_delay_slots (1);
fill_simple_delay_slots (0);
fill_eager_delay_slots ();
relax_delay_slots (first);
or
// fill_simple_delay_slots (1);
fill_simple_delay_slots (0);
fill_eager_delay_slots ();
relax_delay_slots (first);
-> produces bad code.
fill_simple_delay_slots (1);
fill_simple_delay_slots (0);
// fill_eager_delay_slots ();
relax_delay_slots (first);
-> doesn't do anything to the code.
// fill_simple_delay_slots (1);
// fill_simple_delay_slots (0);
fill_eager_delay_slots ();
relax_delay_slots (first);
or
fill_simple_delay_slots (1);
// fill_simple_delay_slots (0);
fill_eager_delay_slots ();
relax_delay_slots (first);
-> results in the following code (looks OK):
mov.l .L8,r1
cmp/ge r1,r5

mov #1,r0
cmp/gt r1,r5
