Rather than hard-coding a separate set of NASM macros, or generating them with a separate function, we can just leverage the C preprocessor to generate a NASM source file *from* the existing ops macros. This is maybe a bit unorthodox, but it avoids unnecessary overhead from re-generating the macros twice, avoids manual updating of the NASM macros, and generally does not come with any real downside except being a bit ugly. The main source of ugliness is the fact that the C preprocessor expands everything into a single line, whereas NASM expects separate statements to be on separate lines. Very fortunately, we can work around this by writing a another NASM macro to take its arguments and dump them onto multiple lines. It may seem premature, but I went ahead and defined all the macros, since it was easy enough to do. I added the %include in this commit to trigger build errors that occur only as a result of introducing this file in the same commit that introduces it. Signed-off-by: Niklas Haas <git@haasn.dev>
