URL: https://github.com/llvm/llvm-project/commit/806bbc49dc07465eddc883b09d48dd93fb64d147 DIFF: https://github.com/llvm/llvm-project/commit/806bbc49dc07465eddc883b09d48dd93fb64d147.diff LOG: [OpenMP] Try to embed offloading objects after codegen Currently we use the `-fembed-offload-object` option to embed a binary file into the host as a named section. This is currently only used as a codegen action, meaning we only handle this option correctly when the input is a bitcode file. This patch adds the same handling to embed an offloading object after we complete code generation. This allows us to embed the object correctly if the input file is source or bitcode.
