Description Rainer Orth 2024-09-04 07:37:21 UTC 
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.

Comment 2 Richard Biener 2024-09-05 07:32:43 UTC 
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...).
