[ELF] - Resolve references properly when using .symver directive This is PR28414. Previously LLD was unable to link following: (failed with undefined symbol bar) Version script: SOME_VERSION { global: *; }; .global _start .global bar .symver _start, bar@@SOME_VERSION _start: jmp bar Manual has next description: .symver name, name2@@nodename In this case, the symbol name must exist and be defined within the file being assembled. It is similar to name2@nodename. The difference is name2@@nodename will also be used to resolve references to name2 by the linker https://sourceware.org/binutils/docs/as/Symver.html Patch implements that. If we have name@@ver symbol and name is undefined, name@@ver is used to resolve references to name. If name is defined then multiple definition error is emited, that is consistent with what bfd do. Differential revision: https://reviews.llvm.org/D33680 llvm-svn: 307077
