Bug ID: 111891
Summary: ICE regression, in vectorizable_simd_clone_call, at
tree-vect-stmts.cc:4073 on x86_64, gfortran
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: mjires at suse dot cz
CC: rguenth at gcc dot gnu.org
Target Milestone: ---
Following minimized example leads to ICE on x86_64 with -O[2,3,fast}
-march=native.
Bisection points to commit r14-4628-g63eaccd114393f
(63eaccd114393f4692976bb78b30148e6d77a89e).
PARAMETER (NX=3, G=1.4)
DIMENSION T(NX,NX), P(NX,NX)
INTEGER Apx
COMMON P, T
DO i = 1, 3
IF (i < 0.0 ) THEN
P(Apx,i) = i**G
T(Apx,i) = i**G
ELSE
P(Apx,i) = 0
T(Apx,i) = 0
ENDIF
