[PATCH] D65497: [RISCV] Generate extensions for RV64 when lowering LibCall with i32 type

[Sam Elliott via Phabricator via llvm-commits]

lenary added a comment.

I thought the problem was in that in the complex add case, we needed to zero-extend the i32 into an i64, in order to zero the upper 32 bits. This patch seems to sign-extend the libcall instead. Is there a `shouldZeroExtendTypeInLibCall` callback?
