Bug ID: 35189
Summary: r314561/r314622 + NewGVN cause crash/build failure
with LibreOffice
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: lukebe...@hotmail.com
CC: llvm-bugs@lists.llvm.org
Before r314561, I could build LibreOffice with the NewGVN. After r314561, clang
would crash building the firebird module. After r314622, the build fails during
the basic Unit Testing phase.
Steps to reproduce:
1. $ git clone git://anongit.freedesktop.org/libreoffice/core
2. $ apt-get build-dep libreoffice
3. create file autogen.input with CC=clang and CXX=clang++
4. ./autogen.sh && make ENVCFLAGS="-mllvm -enable-newgvn" ENVCFLAGSCXX="-mllvm
-enable-newgvn"
