Subject: Allow the compiler driver to link the libclang_rt.profile library.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=ab29ea966281b9858a45bf031eac47d2ab1cd59c;p=openbsd

Allow the compiler driver to link the libclang_rt.profile library.

With this change, passing -fprofile-instr-generate -fcoverage-mapping
when building programs will attempt linking against libclang_rt.profile.a.

Please note that we do not ship the library yet.

OK jca@
