Bug ID: 89535
Summary: [9 Regression] ICE when building 416.gamess in
prepare_load_store_mask
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
CC: rsandifo at gcc dot gnu.org
Target Milestone: ---
Target: aarch64
I get an ICE when building 416.gamess with -O2 -ftree-vectorize
-march=armv8.4-a+sve -funconstrained-commons -w -std=legacy on aarch64
The reduced testcase is:
SUBROUTINE FOO(ISH,JSH,P1,P2)
PARAMETER (MXGTOT=5000, MXGSH=30)
DIMENSION TMP2(MXGSH), CCBS(MXGSH)
DIMENSION TMP1(MXGTOT,5)
DIMENSION P1(15,*)
LOGICAL SPI,SPJ
COMMON LIT,LOCI,MINI,NIJ
LOCI=KLOC(ISH)-MINI
SPI=LIT.EQ.2.AND.MINI.EQ.1
DO 10 I=I1,I2
NGA=NGA+1
IF(SPI) TMP2(NGA)=TMP1(I,1)/TMP1(I,2)
10 CONTINUE
DO 20 J=J1,J2
IF(SPJ) CCBS(NGB)=TMP1(J,1)/TMP1(J,2)
20 CONTINUE
NIJ=0
DO 300 IA=1,NGA
DO 200 JB=1,NGB
IF(DUM.GT.RTOL) GO TO 200
IF(DUM.LE.DTOL) GO TO 200
IF(SPI) P1(14,NIJ+P2)=TMP2(IA)
IF(SPJ) P1(15,NIJ+P2)=CCBS(JB)
200 CONTINUE
300 CONTINUE
RETURN
END
The ICE is:
