This is a silly question, but I am in a situation where I need to build x86 and arm assembly sources for some sources while the rest will be built with C. I do know that just adding
-fembed-bitcode to a C sources would embed bitcode, but doing the same for the assembly files will not do that (at least, it will add the 1-byte
_LLVM,__asm section, but not the
__LLVM,__bitcode section). Furthermore, I do need the final output to contain bitcode for all files used.
So, my question is if it is possible to add the
__LLVM,__bitcode section later to the MachO object file. I tried to archive the bitcode using
xar and run
llvm-objcopy main.o --add-section=__LLVM,__bitcode=main.xar main2.o, but it failed with an
unsupported load command. This seems to be the case for all usages of
llvm-objcopy with MachO files.
Cheers and thanks
