Subject: ARM: embedded v7 'darwin' doesn't get min-version defines.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5f96d3cbdd72f3074dfb544be67441ed2199a346;p=clang

ARM: embedded v7 'darwin' doesn't get min-version defines.

Make sure armv7 doesn't get the iOS deployment version definitions when
it's being used for non-iOS.
