Subject: radeon/llvm: Implement radeon_llvm_parse_bitcode() using C API
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7e9abbea15bf6ff717c1908870d9c2de219d69b4;p=mesa.git

radeon/llvm: Implement radeon_llvm_parse_bitcode() using C API

Also make the function static since it is not used anywhere else.
