[Qemu-devel] [PATCH 0/2] tcg: tcg_can_emit_vec_op cleanup+fix

Posted by Richard Henderson 7 years, 8 months ago

While rearranging/rebasing my SVE patch set, I triggered an
assert in tcg_gen_mul_vec.  Turns out we should not have gone
down that path, due to a missing tcg_can_emit_vec_op check.

Tidy the usage of tcg_can_emit_vec_op to avoid code clutter.
