# This tool creates a shared library from the LLVM libraries. Generating this
|
|
# library is enabled by setting LLVM_BUILD_LLVM_DYLIB=yes on the CMake
|
|
# commandline. By default the shared library only exports the LLVM C API.
|
|
|
|
|
|
# You can configure which libraries from LLVM you want to include in the shared
|
|
# library by setting LLVM_DYLIB_COMPONENTS to a semi-colon delimited list of
|
|
# LLVM components. All compoenent names handled by llvm-config are valid.
