Summary: Follow up to [x32] "Use ebp/esp as frame and stack pointer": http://reviews.llvm.org/D4617 In that earlier patch, NaCl64 was made to always use rbp. That's needed for most cases because rbp should hold a full 64-bit address within the NaCl sandbox so that load/stores off of rbp don't require sandbox adjustment (zeroing the top 32-bits, then filling those by adding r15). However, llvm.frameaddress returns a pointer and pointers are 32-bit for NaCl64. In this case, use ebp instead, which will make the register copy type check. A similar mechanism may be needed for llvm.eh.return, but is not added in this change.
