Commit Message

Christophe Lyon via Gcc-patches April 2, 2020, 7:24 a.m.
For operands with an identical set of alternatives there is no point
in marking them commutative.  This patch removes the superfluous
constraint modifiers in vector.md and vx-builtins.md since it might
slow down reload without buying us anything.

There were even two patterns where the constraint modifier was plain
wrong: "sub<VF_HW>3" and "ior_not<VT>3". Fortunately it never had any effect.

Bootstrapped and regression tested on s390x.

SPEC binaries built with and without the patch are identical.
