Bug ID: 82436
Summary: 465.tonto ICE in vect_get_slp_vect_defs, at
tree-vect-slp.c:3410
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
Target: i?86-*-*
With -Ofast -march=core-avx2 -flto -m32.
We are vectorizing
do n=1,n_refl
y = y + abs(F_z_(ext_refs(n)))
w = w + abs(F_r_(ext_refs(n)))
end do
from put_fcalc_plots which looks like the following before vectorization:
<bb 47> [84.24%] [count: INV]:
# _649 = PHI <1(46), _118(48)>
# y_lsm.44_396 = PHI <0.0(46), _113(48)>
# w_lsm.45_24 = PHI <0.0(46), _117(48)>
_104 = _103 * _649;
_105 = _102 + _104;
_107 = _105 * _106;
_108 = (sizetype) _107;
_109 = _101 + _108;
_651 = MEM[(struct reflection_type &)_109].f_pred;
_652 = MEM[(struct reflection_type &)_109].f_exp;
_653 = _651 - _652;
_655 = MEM[(struct reflection_type &)_109].f_sigma;
res_656 = _653 / _655;
_111 = ABS_EXPR <res_656>;
_113 = _111 + y_lsm.44_396;
res_648 = _653 / _652;
_115 = ABS_EXPR <res_648>;
_117 = _115 + w_lsm.45_24;
_118 = _649 + 1;
if (_118 > res_485)
goto <bb 49>; [15.00%] [count: INV]
else
goto <bb 48>; [85.00%] [count: INV]
<bb 48> [71.60%] [count: INV]:
goto <bb 47>; [100.00%] [count: INV]
all types are doubles. The reflection_type is
type reflection_type
INT :: h
! Miller h index for the reflection
INT :: k
! Miller k index for the reflection
INT :: l
! Miller l index for the reflection
REAL :: F_exp
! Experimental structure factor
REAL :: F_sigma
! Experimental error in the structure factor
CPX :: F_calc
! Calculated complex structure factor without including corrections
REAL :: F_pred
! Calculated structure factor including scale and extinction corrections
REAL :: I_exp
! Experimental intensity
REAL :: I_sigma
! Experimental error in the intensity
REAL :: I_pred
! Calculated intensity including scale and extinction corrections
end type
where INT is int32_t and CPX is _Complex double.
