GNU ld's manual says that TARGET(foo) is basically an alias for `--format foo` where foo is a BFD target name such as elf64-x86-64. Unlike GNU linkers, lld doesn't allow arbitrary BFD target name for --format. We accept only "default", "elf" or "binary". This makes situation a bit tricky because we can't simply make TARGET an alias for --target. A quick code search revealed that the usage number of TARGET is very small, and the only meaningful usage is to switch to the binary mode. Thus, in this patch, we handle only TARGET(elf.*) and TARGET(binary). Differential Revision: https://reviews.llvm.org/D48153 llvm-svn: 339060
