Fix for PR5967: Make const-marking for LLVM globals correct for cases requiring run-time initialization, and emit run-time initializers aggresively to avoid ordering issues with deferred globals. llvm-svn: 92976

// RUN: %clang_cc1 %s -emit-llvm -o - | FileCheck %s
// PR5967
extern void* foo;
static void* const a = foo;
void* bar() { return a; }
Mangle static variables with an extra name to distinguish them from non-static variables in the same TU. Fixes PR5966 for real this time; also reverts r92911, which had a incorrect fix. llvm-svn: 94352

C++: Add support for -fno-use-cxa-atexit. - So much typing, so little gain... Also, rename the __cxx_global_initialization function just to match llvm-gcc. llvm-svn: 99039
