[LLVMdev] Possible Typo in SelectionDAGLowering::visitShuffleVector
Hello
While building LLVM, the compiler (static analysis) is giving me a warning
about "if (RangeUse[0] == 0 && RangeUse[0] == 0) {".
Can somebody familar with the codebase look over it, maybe this should be
"if (RangeUse[0] == 0 && RangeUse[1] == 0) {", otherwise sorry for the
noise.

[LLVMdev] Question on SelectionDAGBuilder
...er computing min/max
values of the mask for each operand, there's a look that looks at the ranges
and determines whether an EXTRACT_SUBVECTOR can be used:
for (int Input=0; Input < 2; ++Input) {
if (MinRange[Input] == (int)(SrcNumElts+1) && MaxRange[Input] == -1) {
RangeUse[Input] = 0; // Unused
StartIdx[Input] = 0;
} else if (MaxRange[Input] - MinRange[Input] < (int)MaskNumElts) {
// Fits within range but we should see if we can find a good
// start index that is a multiple of the mask length.
if (MaxRange[Input] < (int)Mas...
