488  * AMD64 support. Microsoft uses a different calling convention
489  * than everyone else on the amd64 platform. Sadly, gcc has no
490  * built-in support for it (yet).
491  *
492  * The three major differences we're concerned with are:
493  *
494  * - The first 4 register-sized arguments are passed in the
495  *   %rcx, %rdx, %r8 and %r9 registers, and the rest are pushed
496  *   onto the stack. (The ELF ABI uses 6 registers, not 4).
497  *
498  * - The caller must reserve space on the stack for the 4
499  *   register arguments in case the callee has to spill them.
500  *
501  * - The stack myst be 16-byte aligned by the time the callee
502  *   executes. A call instruction implicitly pushes an 8 byte
503  *   return address onto the stack. We have to make sure that
504  *   the amount of space we consume, plus the return address,
505  *   is a multiple of 16 bytes in size. This means that in
506  *   some cases, we may need to chew up an extra 8 bytes on
507  *   the stack that will be unused.
508  *
509  * On the bright side, Microsoft seems to be using just the one
510  * calling convention for all functions on amd64, unlike x86 where
511  * they use a mix of _stdcall, _fastcall and _cdecl.
