Bug ID: 106928
Summary: 500.perlbench_r fail(VE) since r13-1933
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: guojiufu at gcc dot gnu.org
Target Milestone: ---
With the latest trunk, the 500.perlbench_r (-Ofast) from spec2017 encounter VE
on power9 and power10 on no matter with or without
-fno-unsafe-math-optimizations.
With bisect, the commit may be r13-1933 (Implement basic range operators to
enable floating point VRP).
One compiling command:
gcc -std=c99 -m64 -c -o reentr.o -DSPEC -DNDEBUG -DPERL_CORE -I.
-Idist/IO -Icpan/Time-HiRes -Icpan/HTML-Parser -Iext/re -Ispecrand
-DDOUBLE_SLASHES_SPECIAL=0 -DSPEC_AUTO_SUPPRESS_OPENMP -D_LARGE_FILES
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -Ofast
-fno-unsafe-math-optimizations -DSPEC_LINUX_PPC_LE
-fno-strict-aliasing -fgnu89-inline -DSPEC_LP64 reentr.c
In configure, I use:
default=base: # flags for all base
OPTIMIZE = -Ofast -fno-unsafe-math-optimizations
FOPTIMIZE = -std=legacy
intrate,intspeed=base: # flags for integer base
EXTRA_COPTIMIZE = -fno-strict-aliasing -fgnu89-inline
