Subject: Driver/Darwin: Don't link -lgcc_s.1 when compiling as iOS for the simulator,
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=87e945f0f1fb5778c4c6b9e61356c7f1571b9cb4;p=clang

Driver/Darwin: Don't link -lgcc_s.1 when compiling as iOS for the simulator,
that library has never been in the SDK. Fortunately, it shouldn't be necessary,
since that library was also removed in 10.6.
