__unaligned is not currently mangled in any way in the Itanium ABI. This causes failures when using -fms-extensions and C++ in targets using Itanium ABI. As suggested by @rsmith the simplest thing to do here is actually mangle the qualifier as a vendor extension. This patch also removes the change done in D31976 and updates its test to the new reality. This fixes https://bugs.llvm.org/show_bug.cgi?id=33080 https://bugs.llvm.org/show_bug.cgi?id=33178 Differential Revision: https://reviews.llvm.org/D33398 llvm-svn: 304523
