[LLVMdev] How to make Polly ignore some non-affine memory accesses

Mmm, about this I think that depends on the fact that I'm still quite
unexperienced on the topic and fail to be "optimal" in doing some
things.
In the old version of Polly in ScopDetection (isValidMemoryAccess
function) there was an "isValidAffineFunction" that detected if the
access function was affine or not. That function initialized a "Value*
" pointer used for alias analysis later in the isValidMemoryAccess
function itself. If the "isValidAffineFunction" failed that pointer
was left uninitialized. I needed a way to g...

Great.

Ups, sorry! However, I believe without these changes detecting
non-affine memory

[LLVMdev] How to make Polly ignore some non-affine memory accesses
Mmm I found out a very strange behavior (to me) of the SCEV analysis
of the loop bound of the external loop I posted.
When in ScopDetection it gets the SCEV of the external loop bound in
the "isValidLoop()" function with:
const SCEV *LoopCount = SE->getBackedgeTakenCount(L);
It returns a SCEVCouldNotCompute, but if I change the "if" block
inside the loop from:
if
