Subject: [builtins] Canonicalize PowerPC detection macros to __powerpc__
X-Git-Tag: upstream/17.0.6~28391
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0f91ec243d6ddb1f8b1f80d15f9003e5f06b0a21;p=platform%2Fupstream%2Fllvm.git

[builtins] Canonicalize PowerPC detection macros to __powerpc__

The lowercase __ppc__ is not defined by Linux GCC, therefore it lures
users to write code which is not portable to GCC. Migrate to __powerpc__ in
preparation for undefining __ppc__. __powerpc__ is much more common than
__PPC__.
