/*
* EFI calling conventions are documented at:
* http://msdn.microsoft.com/en-us/library/ms235286%28v=vs.80%29.aspx
* ELF calling conventions are documented at:
* http://www.x86-64.org/documentation/abi.pdf
*
* Basically here are the conversion rules:
* a) our function pointer is in %rdi
* b) rsi through r8 (elf) aka rcx through r9 (ms) require stack space
* on the MS side even though it's not getting used at all.
* c) 8(%rsp) is always aligned to 16 in ELF, so %rsp is shifted 8 bytes extra
* d) arguments are as follows: (elf -> ms)
* 1) rdi -> rcx (32 saved)
* 2) rsi -> rdx (32 saved)
* 3) rdx -> r8 (32 saved)
* 4) rcx -> r9 (32 saved)
* 5) r8 -> 32(%rsp) (32 saved)
* 6) r9 -> 40(%rsp) (48 saved)
* 7) 8(%rsp) -> 48(%rsp) (48 saved)
* 8) 16(%rsp) -> 56(%rsp) (64 saved)
* 9) 24(%rsp) -> 64(%rsp) (64 saved)
* 10) 32(%rsp) -> 72(%rsp) (80 saved)
* e) because the first argument we recieve in a thunker is actually the
* function to be called, arguments are offset as such:
* 0) rdi -> caller
* 1) rsi -> rcx (32 saved)
* 2) rdx -> rdx (32 saved)
* 3) rcx -> r8 (32 saved)
* 4) r8 -> r9 (32 saved)
* 5) r9 -> 32(%rsp) (32 saved)
* 6) 8(%rsp) -> 40(%rsp) (48 saved)
* 7) 16(%rsp) -> 48(%rsp) (48 saved)
* 8) 24(%rsp) -> 56(%rsp) (64 saved)
* 9) 32(%rsp) -> 64(%rsp) (64 saved)
* 10) 40(%rsp) -> 72(%rsp) (80 saved)
* f) arguments need to be moved in opposite order to avoid clobbering
