# As of 06-May-2012, LLVM 3.0 doesn't seem to build for win64. It gets
# a lot of undefined symbols in the "Linking Release Shared Library
# LLVM-3.0.dll" phase.  I'll need help from upstream to deal with that,
# so for now, only build for win32.

# Data files should be installed with timestamps preserved.
Patch0:         llvm-2.6-timestamp.patch

# Fedora MinGW-specific patch to undef environment variables
# set by mingw_configure macro.  The env vars simplify making
# most packages build for MinGW.  The LLVM build system is
# already MinGW-aware, so the evn vars not only don't help,
# they actually break the build by preventing some necessary
# build-host tools from building correctly.
Patch100:       llvm-3.0-mingw-undef.patch

# Fedora MinGW-specific patch to remove llvm-config logic that
# tries to figure out where llvm-config is running from.  We
# *ALWAYS* use the configured PREFIX.

%description
LLVM is a compiler infrastructure designed for compile-time,
link-time, runtime, and idle-time optimization of programs from
arbitrary programming languages.  The compiler infrastructure includes
mirror sets of programming tools as well as libraries with equivalent
functionality.

%changelog
* Thu May 10 2012 Eric Smith <eric@brouhaha.com> - 3.0-3
- Add patch to force llvm-config to always use PREFIX, rather than
  trying to figure out whether it has been installed.

* Mon May 07 2012 Eric Smith <eric@brouhaha.com> - 3.0-2
- Add OPTIMIZE_OPTION and KEEP_SYMBOLS to make command line to prevent
  symbols from being stripped, in order to get usable debuginfo package.

* Sun May 06 2012 Eric Smith <eric@brouhaha.com> - 3.0-1
- Initial version
