            Bug ID: 23063
           Summary: libcompiler_rt.a No such file or directory
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: compiler-rt
          Assignee: unassignedbugs at nondot.org

As encountered by Behem0th and myself since a couple of weeks, I am unable to
build LLVM 32bit libs (see comments at
https://aur.archlinux.org/pkgbase/lib32-llvm-svn/).

I tried to build LLVM outside of the Archilinux package by following the steps
http://llvm.org/docs/GettingStarted.html and by using autotools. I simplified
the configuration line as follow:
../src/llvm/configure --prefix=/usr --libdir=/usr/lib32 --sysconfdir=/etc
--with-binutils-include=/usr/include --with-python=/usr/bin/python2
--build=i686-pc-linux-gnu --host=i686-pc-linux-gnu --enable-optimized

Archlinux's lib32 LLVM 3.6 builds fine. So something must have changed between
3.6 an 3.7 dev. Anything I can help with to narrow down what is going on?

Here is the error:
