Subject: Darwin's toolchain should be initialized before openmp offloading
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1775aeb0557c7fb6dd6598fd9793d3433f9f69e0;p=clang

Darwin's toolchain should be initialized before openmp offloading
is processed

This fixes an 'openmp-offload.c' test failure introduced by r310263.
