For `ld64` which uses legacy LTOCodeGenerator, it relies on writeMergedModule to perform `ld -r` (generates a linked object file). If all the inputs to `ld -r` is fullLTO bitcode, `ld64` will linked the bitcode module, internalize all the symbols and write out another fullLTO bitcode object file. This bitcode file doesn't have all the bitcode inputs and it should not have LTOPostLink module flag. It will also cause error when this bitcode object file is linked with other LTO object file. Fix the issue by not applying LTOPostLink flag during writeMergedModule function. The flag should only be added when all the bitcode are linked and ready to be optimized. rdar://problem/58462798 Reviewed By: tejohnson Differential Revision: https://reviews.llvm.org/D84789 |
