Factor out executable format handling into a new file. 2022-09-10 22:06:21 -07:00			`#include "format.h"`
Slightly unfuck codegen for relative jumps and blocks. Still pretty horribly broken. I was generating dispacements backwards, failing to emit stuff like the beginning of loops, the logic for `if` jumps was backwards, etc. I was also completely forgetting to increment file_here for appends. I don't remember what all I did; check the diff. 2022-10-19 12:21:46 -07:00			`#include "x86encode.h"`
