/*
* AMD64 support. Microsoft uses a different calling convention
* than everyone else on the amd64 platform. Sadly, gcc has no
* built-in support for it (yet).
*
* The three major differences we're concerned with are:
*
* - The first 4 register-sized arguments are passed in the
* %rcx, %rdx, %r8 and %r9 registers, and the rest are pushed
* onto the stack. (The ELF ABI uses 6 registers, not 4).
*
* - The caller must reserve space on the stack for the 4
* register arguments in case the callee has to spill them.
*
* - The stack myst be 16-byte aligned by the time the callee
* executes. A call instruction implicitly pushes an 8 byte
* return address onto the stack. We have to make sure that
* the amount of space we consume, plus the return address,
* is a multiple of 16 bytes in size. This means that in
* some cases, we may need to chew up an extra 8 bytes on
* the stack that will be unused.
*
* On the bright side, Microsoft seems to be using just the one
* calling convention for all functions on amd64, unlike x86 where
* they use a mix of _stdcall, _fastcall and _cdecl.
