Bug ID: 26311
Summary: [Polly] Verify use of getNewValue in
RegionBlockGenerator
Product: Polly
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Optimizer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Michael found by inspection that in rare corner cases the loop we choose to
synthesize SCEVs in the RegionBlockGenerator might be incorrect.
For details see:
http://reviews.llvm.org/D16522?id=45860#inline-136211
We can not currently write test cases to investigate this bug further as the
domain generation does not yet handle non-affine-loop regions well.
