+/* This code is equivalent to emitx64.c but pre-allocates stack
+ * space and uses mov instead of push/pop instructions to access
+ * the temporary stack. It runs in similar time, but uses 3*n
+ * more bytes, where n is number of push/pop instructions.
+ *
+ * This code is preferred because it keeps the stack aligned on a
+ * 16 byte boundary.
+ *
+ * Improvements:
+ * Doesn't call stub functions, does all the work inline.
+ * Has optimisations for loading i64s to stack.
