Bug ID: 116596
Summary: gcc.dg/vect/slp-11a.c FAILs
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: sparc*-sun-solaris2.11
The recent gcc.dg/vect/slp-11a.c test FAILs on Solaris/SPARC (32 and 64-bit):
+FAIL: gcc.dg/vect/slp-11a.c -flto -ffat-lto-objects scan-tree-dump-times vect
"vectorizing stmts using SLP" 1
+FAIL: gcc.dg/vect/slp-11a.c scan-tree-dump-times vect "vectorizing stmts using
SLP" 1
There are a couple of potential issues with vectorization, so I'm rather
attaching the whole dump.

Thanks for reporting - I'm only able to test x86, arm, aarch64 and riscv with
the vectorizer changes. I'll investigate at some later point, but possibly the
issue will resolve itself (well, you can hope...).
