Subject: Use llvm::Triple's methods to parse FreeBSD version numbers.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=474202f657239f4169f8ff8db844e19558daa637;p=clang

Use llvm::Triple's methods to parse FreeBSD version numbers.

Who could've thought that FreeBSD would ever reach version 10!
Patch from Dimitry Andric.
