Subject: Make a modern Objective-C runtime the default target for *BSD.  Don't yet change... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c3cb07205a18d51b0cfff5d431579d5930277ee0;p=clang

Make a modern Objective-C runtime the default target for *BSD.  Don't yet change this on GNU/Linux, where the GCC runtime still tends to be used.
