Bug ID: 26420
Summary: Compilation of attached code with -O2 takes infinitely
long, -O1 works.
Product: clang
Version: 3.7
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

Classification: Unclassified

--> https://llvm.org/bugs/attachment.cgi?id=15789&action=edit
Auto-generated clang script
The attached auto-generated code takes infinitely long with optimization level
2 (-O2). When switching to -O1, it works fine.
Using clang on ArchLinux:
clang version 3.7.1 (tags/RELEASE_371/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix
Maybe that's already fixed in upstream, and somebody could quickly test that
with the attached scripts/source file.
