Windows on ARM uses a pure thumb-2 environment. This means that it can select a high register when doing a __builtin_longjmp. We would use a tLDRi which would truncate the register to a low register. Use a t2LDRi12 to get the full register file access. Tweak the code to just load into PC, as that is an interworking branch on all supported cores anyways. llvm-svn: 274815
