* Added a --shared option to build LLVM as a shared library. (Shouldn't be used with --universal as it will cause the build to fail) * Added a --rtti option to build LLVM with RTTI information. (Can be used, for example, to build LLVM for use with Rubinius) Closes Homebrew/homebrew#3847. Signed-off-by: Mike McQuaid <mike@mikemcquaid.com>

If you already have LLVM installed, then "brew upgrade llvm" might not
|
|
work. Instead, try:
|
|
$ brew rm llvm
|
|
$ brew install llvm
