2010-08-25Change handling of illegal vector types to widen when possible instead of Chris Lattner
expanding: e.g. <2 x float> -> <4 x float> instead of -> 2 floats. This affects two places in the code: handling cross block values and handling function return and arguments. Since vectors are already widened by legalizetypes, this gives us much better code and unblocks x86-64 abi and SPU abi work. For example, this (which is a silly example of a cross-block value): define <4 x float> @test2(<4 x float> %A) nounwind { %B = shufflevector <4 x float> %A, <4 x float> undef, <2 x i32> <i32 0, i32 1> %C = fadd <2 x float> %B, %B br label %BB BB: %D = fadd <2 x float> %C, %C %E = shufflevector <2 x float> %D, <2 x float> undef, <4 x i32> <i32 0, i32 1, i32 undef, i32 undef> ret <4 x float> %E } Now compiles into: _test2: ## @test2 ## BB#0: addps %xmm0, %xmm0 addps %xmm0, %xmm0 ret previously it compiled into: _test2: ## @test2 ## BB#0: addps %xmm0, %xmm0 pshufd $1, %xmm0, %xmm1 ## kill: XMM0<def> XMM0<kill> XMM0<def> insertps $0, %xmm0, %xmm0 insertps $16, %xmm1, %xmm0 addps %xmm0, %xmm0 ret This implements rdar://8230384 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112101 91177308-0d34-0410-b5e6-96231b3b80d8
