// AMD64 calling convention is:
// - args pass in: RDI, RSI, RDX, RCX, R08, R09
// - return value in RAX
// - stack must be aligned on a 16-byte boundary before all calls
// - RAX, RCX, RDX, RSI, RDI, R08, R09, R10, R11 are caller-save
// - RBX, RBP, R12, R13, R14, R15 are callee-save
// In the functions below, argument order follows x86 docs and generally
// the destination is the first argument.
// NOTE: this is a change from the old convention used in this file and
// some functions still use the old (reverse) convention.
