[LLVMdev] [PATH] Fixes for the amd64 JIT code

[Zoltan Varga]

Hi,

  I can't reproduce these failures on my linux machine. The test machine
seems to be
running darwin. I suspect that the problem might be with RIP relative
addressing, or with
the encoding of R12/R13, but the code seems to handle the latter, since it
checks for
ESP/EBP which is the same as R12/R13.
