[PATCH] D70398: [lld] Support copy relocations for TLS symbols

[James Clarke via Phabricator via llvm-commits]

jrtc27 added a comment.

I think the fact that many runtime linkers out there don't handle it correctly is a pretty compelling reason in and of itself (but I agree that, being a new ABI, it should avoid introducing more copy relocations). The fact that GCC relies on this behaviour (which glibc and bfd correctly implement) but doesn't document it anywhere other than in the compiler source itself is worrying, since it leads to the situation we have now where binaries built by GCC+bfd for other systems (such as FreeBSD) may not run correctly, as they will copy garbage from early on in the mapping.
