Bug ID: 29113
Summary: LLVM doesn't fold fadd on ppc_fp128 correctly
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: PowerPC
Assignee: unassignedb...@nondot.org
Reporter: timshe...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified

Reduced test case
Constant folding on ppc_fp128 seems wrong, since the hardware makes the
attached program return 0 (not reproducible with the .ll file, but with the .cc
file), while the backend folds it to 0.
