Bug #: 56049
Summary: [4.8 Regression] Simplification to constants not done
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: tkoenig@gcc.gnu.org
>From http://gcc.gnu.org/ml/fortran/2013-01/msg00158.html :
program inline
integer i
integer a(8,8), b(8,8)
a = 0
do i = 1, 10000000
call add(b, a, 1)
a = b
end do
print *, a
contains
subroutine add(b, a, o)
integer, intent(inout) :: b(8,8)
integer, intent(in) :: a(8,8), o
b = a + o
end subroutine add
end program inline
is simplified all the way to the final constant with 4.6 and
4.7 (example for 4.6.2):
;; Function inline (MAIN__) (executed once)
inline ()
{
struct array2_integer(kind=4) parm.3;
struct __st_parameter_dt dt_parm.2;
integer(kind=4) a[64];
<bb 2>:
a = {};
MEM[(integer(kind=4)[64] *)&a] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 4B] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 8B] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 12B] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 16B] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 20B] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 24B] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 28B] = 10000000;
MEM[(integer(kind=4)[64] *)&a + 32B] = 10000000;
... and so on. Current trunk converts this to
;; Function inline (MAIN__, funcdef_no=0, decl_uid=1874, cgraph_uid=1)
(executed once)
inline ()
{
vector(4) integer(kind=4) vect_var_.16;
vector(4) integer(kind=4) vect_var_.15;
vector(4) integer(kind=4) vect_var_.14;
struct array2_integer(kind=4) parm.3;
struct __st_parameter_dt dt_parm.2;
integer(kind=4) b[64];
integer(kind=4) a[64];
unsigned int ivtmp_153;
unsigned int ivtmp_154;
<bb 2>:
a = {};
<bb 3>:
# ivtmp_154 = PHI <10000000(2), ivtmp_153(4)>
vect_var_.14_1 = MEM[(integer(kind=4)[64] *)&a];
vect_var_.15_42 = MEM[(integer(kind=4)[64] *)&a + 16B];
vect_var_.16_43 = vect_var_.14_1 + { 1, 1, 1, 1 };
vect_var_.16_44 = vect_var_.15_42 + { 1, 1, 1, 1 };
MEM[(integer(kind=4)[64] *)&b] = vect_var_.16_43;
MEM[(integer(kind=4)[64] *)&b + 16B] = vect_var_.16_44;

Since http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=193570 you need:
--param max-completely-peeled-insns=129
to make this happen, as the defaults were lowered from 400 to 100.

Programs optimizing to a constant are artifical enough to mark this WONTFIX.
The lowering was deliberate to not grow object size too much.
Maybe Honza want's to investigate why heuristics do not detect the
all-constant outcome.

Honza. Are you interested in investigating this as Richard suggests, or can we
close this as WONTFIX?

Well, I think we should try to toamn fantasy of our optimizers here. What
unroller sees at -O3 -fno-tree-vectorize is quite ugly:
<bb 2>:
a = {};
<bb 3>:
# i_1 = PHI <1(2), i_7(7)>
# prephitmp_99 = PHI <0(2), pretmp_98(7)>
# prephitmp_102 = PHI <0(2), pretmp_101(7)>
# prephitmp_105 = PHI <0(2), pretmp_104(7)>
# prephitmp_108 = PHI <0(2), pretmp_107(7)>
# prephitmp_111 = PHI <0(2), pretmp_110(7)>
# prephitmp_114 = PHI <0(2), pretmp_113(7)>

# S.0_90 = PHI <S.0_36(5), 1(3)>

# prephitmp_129 = PHI <pretmp_128(5), prephitmp_102(3)>
# prephitmp_132 = PHI <pretmp_131(5), prephitmp_105(3)>

pretmp_130 = pretmp_122 + -6;
pretmp_131 = a[pretmp_130];
pretmp_133 = pretmp_122 + -5;
pretmp_134 = a[pretmp_133];

pretmp_139 = pretmp_122 + -3;
pretmp_140 = a[pretmp_139];
pretmp_142 = pretmp_122 + -2;
pretmp_143 = a[pretmp_142];
pretmp_145 = pretmp_122 + -1;
pretmp_146 = a[pretmp_145];
goto <bb 4>;
With vectorization we actually unroll the inner loop but the outer one gets so
ugly that we don't do much about it...
So what about keeping it as enhancement request? I will try to poke about it,
but htere is but about PR overactivity of this type already, right?

Not that I know of (well there is some about PRE over-activity creating
lots of PHI nodes like this). Yes, keep it as enhancement request
I suppose.
Does the unroller even look at PHI nodes for costs?
