[LLVMdev] scalarrepl fails to promote array of vector
Hi Chris, Thanks for your reply. You said that scalarRepl gets shy about loads and stores of the entire aggregate. Then I use a test case: ; ModuleID = 'test1.ll' define i32 @fun(i32* nocapture %X, i32 %i) nounwind uwtable readonly { %stackArray = alloca <4 x i32> %XC = bitcast i32* %X to <4 x i32>* %arrayVal = load <4 x i32>* %XC store <4 x i32> %arrayVal, <4 x i32>* %stackArray %arrayVal1 = load <4 x i32>* %stackArray %1 = extractelement <4 x i32> %arrayVal1, i32 1 ret i32 %1 } $ opt...

[LLVMdev] scalarrepl fails to promote array of vector
Hi all, I want to use scalarrepl pass to eliminate the allocation of mat_alloc which is of type [4 x <4 x float>] in the following program. $cat test.ll ; ModuleID = 'test.ll' define void @main(<4 x float>* %inArg, <4 x float>* %outArg, [4 x <4 x float>]* %constants) nounwind { entry: %inArg1 = load <4 x float>* %inArg %mat_alloc = alloca [4 x <4 x
