For '--target=amdgcn-amdhsa' (tested '-march=gfx908', '-march=gfx1100'),
I see:
PASS: gcc.dg/vect/slp-26.c (test for excess errors)
PASS: gcc.dg/vect/slp-26.c execution test
PASS: gcc.dg/vect/slp-26.c scan-tree-dump-times vect "vectorized 1 loops" 1
[-PASS:-]{+FAIL:+} gcc.dg/vect/slp-26.c scan-tree-dump-times vect
"vectorizing stmts using SLP" 1
gcc.dg/vect/slp-26.c: pattern found 2 times
..., so I suppose I'll apply the same change to 'amdgcn-*-*' as you did
to 'riscv_v'?
