/*
 * 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.
