Subject: only support int128_t on 64-bit and larger targets.  32-bit targets don't
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4d150c84514dbf15975960a3ea46bdf6b7f16a5b;p=clang

only support int128_t on 64-bit and larger targets.  32-bit targets don't
have support for __divti3 and friends.
