[PATCH] D109228: [AMDGPU][GlobalISel] Legalize G_MUL for non-standard types

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

Seems reasonable to me. I guess the alternative is to remove this restriction from LegalizerHelper::narrowScalarMul:

  if (DstSize % NarrowSize != 0 || SrcSize % NarrowSize != 0)
    return UnableToLegalize;

but that would be more work and the generated code would be the same.
