For cris-elf (no SIMD), the following tests regressed just as
for the similar tests mentioned in PR58556. These apparently
don't fail for the targets mentioned there for some reason, but
I see in the mail thread with the quoted subject there was no
conscious adjustment to the test-suite. Thus I believe
arbitrary per-target fallout is to be expected. Copying the
adjustments from commit r203057, I committed the following as
obvious, after checking that the tests still pass on
x86_64-linux-gnu.
There's also gen-vect-32.c that didn't vectorize but the
adjustment below didn't help and I don't see why that 16-char
loop shouldn't be "vectorized" to 4 32-bit moves (assuming
that's the intended optimization), so I'll open a PR for that.
gcc/testsuite:
* gcc.dg/tree-ssa/gen-vect-11.c: Use dynamic vector cost model.
gcc.dg/tree-ssa/gen-vect-11a.c: Likewise.
gcc.dg/tree-ssa/gen-vect-2.c: Likewise.
gcc.dg/tree-ssa/gen-vect-25.c: Likewise.
