LLVM backend for 6502

The Win64 epilogue structure is very restrictive, it permits a very small number of opcodes and none of them are 'mov'. This means that given: mov %rbp, %rsp pop %rbp The mov isn't the epilogue, only the pop is. This is problematic unless a frame pointer is present in which case we are free to do whatever we'd like in the "body" of the function. If a frame pointer is present, unwinding will undo the prologue operations in reverse order regardless of the fact that we are at an instruction which is reseting the stack pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230543 91177308-0d34-0410-b5e6-96231b3b80d8 |
