Subject: [Driver] Always use -z separate-code with lld on Fuchsia
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=33ced14ac67b64bde28826f184bf2677d131e2fd;p=clang

[Driver] Always use -z separate-code with lld on Fuchsia

Previously -z separate-code was the default lld behavior, but now it
has to be explicitly requested by specifying the flag.
