Bug ID: 28564
Summary: [SeparateConstOffsetFromGEP] split-gep-and-gvn.ll and
split-gep-and-gvn-addrspace-addressing-modes.ll tests
fail
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Scalar Optimizations
Assignee: wujing...@gmail.com
Reporter: david.majne...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The logic in andIRFlags/copyIRFlags didn't handle the inbounds attribute, this
caused GVN to miscompile. With this fixed in r275532, split-gep-and-gvn.ll and
split-gep-and-gvn-addrspace-addressing-modes.ll both fail. This is likely to a
missing inbounds flag on a GEP which later got CSE'd by GVN.
