I'm trying the following code on X86: define <3 x i32> @retThree( ) { ret <3 x i32> <i32 1, i32 2, i32 3 > } expecting it to load the three first lanes of %xmm0. (If returning a vector of four, %xmm0 is used). But the generated assembly seems to be using the method of return by hidden pointer. This despite that the generated assembly seems to have allocated the vector

Hi all, I am working on a target that has support for v4i16 vectors, and no support for v4i8 / v8i8 / v8i16 V4i8 is promoted to v4i16 which is nice V8i16 is split to 2 x v4i16 which is nice as well Now v8i8 is scalarized, which is not so nice. Ideally I would like v8i8 to be first promoted to v8i16 then split to 2xv4i16 (or split to 2xV4i8 then promoted to 2xv4i16) Is there a way to achieve
