On mips64el target there are same fail for now (r258364).
FAIL: gcc.dg/vect/pr79347.c -mmsa scan-tree-dump-not vect "Invalid sum of "
FAIL: gcc.dg/vect/pr79347.c -flto -ffat-lto-objects -mmsa scan-tree-dump-not
vect "Invalid sum of "
After bisected, it's started with r249872.
cross-compile config with:
../configure MISSING=texinfo MAKEINFO=missing --with-mpc=/opt/cfarm/mpc-latest/
--target=mips64el-linux-gnu --enable-languages=c,c++
build cmd:
build/gcc/cc1 -mel -quiet -dumpbase pr79347.c -mmsa -march=mips64r2 -mabi=64
-mllsc -mips64r2 -mno-shared -auxbase-strip pr79347.s -O2 -version
-fdiagnostics-color=never -fno-diagnostics-show-caret -ftree-vectorize
-fvect-cost-model=unlimited -fno-common -fdump-tree-vect-details
-fdump-tree-vect-all -o pr79347.s -fpreprocessed pr79347.i
cat pr79347.i:
...
short *a;
int c;
void n(void)
{
for (int i = 0; i<c;i++)
a[i]++;
}
