Subject: [libc++] Remove redundant conditionals for Apple platforms
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d524fe5b3a0975a1c037669ade35c182681c14f9;p=platform%2Fupstream%2Fllvm.git

[libc++] Remove redundant conditionals for Apple platforms

Summary:
In a bunch of places, we used to check whether LIBCXX_BUILDING_LIBCXXABI
is defined OR we're building for an Apple platform. This used to
be necessary in a time when Apple's build script did NOT define
LIBCXX_BUILDING_LIBCXXABI. However this is not relevant anymore
since Apple's build does define LIBCXX_BUILDING_LIBCXXABI.
