Bug ID: 51960
Summary: [Linux Kernel] 5.14.6 exposes a Polly bug when using
FullLTO
Product: Polly
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Optimizer
Assignee: polly-dev at googlegroups.com
Reporter: m.seyfarth at gmail.com
CC: llvm-bugs at lists.llvm.org
I found a bug when compiling 5.14.6 with LLVM/Clang-14 and filed a report at
https://github.com/ClangBuiltLinux/linux/issues/1460 - after Nick and Nathan
were so kind to debug my findings further (I am not a programmer), Nathan
produced two cvise outputs which I am also posting below. Nick mentioned that
it is probably a Polly issue (polly::simplifyRegion).
I used the following diff:
