[LLVMdev] calling conventions

[Jim Grosbach]

Hi Reed,

It may be useful to have a look at how clang handles this for ARM’s AAPCS and AAPCS_VFP calling conventions. In particular, look in lib/CodeGen/CGCall.cpp and lib/CodeGen/TargetInfo.cpp. That’s probably not going to be exactly what you need, but hopefully it will at least help point in the right direction.

Regards,
  Jim
