            Bug ID: 114072
           Summary: gcc.dg/vect/vect-pr111779.c FAILs
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization

  Target Milestone: ---
            Target: sparc*-sun-solaris2.11

The gcc.dg/vect/vect-pr111779.c test FAILs on 32 and 64-bit Solaris/SPARC
since its introduction:

+FAIL: gcc.dg/vect/vect-pr111779.c -flto -ffat-lto-objects  scan-tree-dump =
vect
"LOOP VECTORIZED"
+FAIL: gcc.dg/vect/vect-pr111779.c scan-tree-dump vect "LOOP VECTORIZED"

The dump has

/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/vect-pr111779.c:26:1=

but I don't know which vect_* keyword would capture this.=
