[PATCH] D148518: [RISCV] Add tests for illegal fixed length vectors that need widened

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.

+; FIXME: This gets expanded instead of widened + promoted
+define <3 x float> @si2fp_v3i7_v3f32(<3 x i7> %x) {
----------------
Just the argument is getting expanded I think? There's a longstanding issue with handling of really odd arguments/returns like this. I think the relevant code is in TargetLoweringBase::getVectorTypeBreakdown
