Subject: [clang] [Driver] [NetBSD] Append -rpath for shared compiler-rt runtimes
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=339f71a59807d64c4749d498d34a74ffdde516c2;p=clang

[clang] [Driver] [NetBSD] Append -rpath for shared compiler-rt runtimes

Append appropriate -rpath when using shared compiler-rt runtimes,
e.g. '-fsanitize=address -shared-libasan'.  There's already a similar
logic in CommonArgs.cpp but it uses non-standard arch-suffixed
installation directory while we want our driver to work with standard
installation paths.
