200 | This change is to address the comment: https://reviews.llvm.org/D108371#inline-1093152 I've updated the debug info in the test to point the loop to |
- Added YAML to LIT test
(This is in response to https://reviews.llvm.org/D108371#inline-1112148)

---|---|---|
565 | Instead of passing in the pointer with a default value of nullptr, can you make it a reference, so that it always gets set, e.g. Value *&UncomputablePtr That also removes the need for the conditional write. | |
llvm/test/Transforms/LoopVectorize/X86/vectorization-remarks-missed.ll | ||
200 | Is this an unrelated change? |
llvm/lib/Analysis/LoopAccessAnalysis.cpp | ||
---|---|---|
565 | Can we please leave it as initialised as nullptr ? The conditional write ensures that the first unsafe dependence gets reported by the remark. if (UncomputablePtr) *UncomputablePtr = Access.getPointer(); | |
llvm/test/Transforms/LoopVectorize/X86/vectorization-remarks-missed.ll | ||
200 | Ok. I've submitted as a separate commit to avoid any confusion. |
llvm/lib/Analysis/LoopAccessAnalysis.cpp | ||
---|---|---|
565 | Ok please ignore the above. I've made the change as suggested, But I didn't remove that bit in the code. if (!UncomputablePtr) UncomputablePtr = Access.getPointer(); |
llvm/lib/Analysis/LoopAccessAnalysis.cpp | ||
---|---|---|
565 |
That should be the choice of the caller, not the callee. If the caller doesn't want the value to be overwritten, it should pass a dummy variable | |
825 | I believe this check should be removed (see my other comment as well) | |
2113 | This variable aliases with UncomputablePtr defined on line 2075. Either pass in the same variable, or give this variable a different name. |
llvm/lib/Analysis/LoopAccessAnalysis.cpp | ||
---|---|---|
2081–2084 | Before this change, recordAnalysis was called unconditionally, but now it is only called if UncomputablePtr is set. I don't think that's intentional, so you can instead just do this: auto *I = dyn_cast_or_null<Instruction>(UncomputablePtr); recordAnalysis("CantIdentifyArrayBounds", I) << "cannot identify array bounds"; | |
2113 | nit: s/UncomputablePtr2/UncomputablePtrUnused/ |
llvm/lib/Analysis/LoopAccessAnalysis.cpp | ||
---|---|---|
2113 | nit: I'm not really a fan of the name, so personally I would prefer to reuse the old variable, e.g. reset it first: UncomputablePtr = nullptr; and then pass that into canCheckPtrAtRT. |
