Bill Currie	717cbaff87	[gamecode] Support offset for lea on globals ... Allows using `array + offset` addressing. Both constant and variable offsets are supported.	2023-05-14 12:45:08 +09:00
Bill Currie	e20aed5c5a	[gamecode] Change address mode B to entity.field ... It turned out that address mode B was redundant as C with 0 offset (immediate) was the same (except for the underlying C code of course, but adding st->b is very cheap). This allowed B to be used for entity.field for all transfer operations. Thus instructions 0-3 are now free as load E became load B, and other than the specifics of format codes for statement printing, transfers+lea are unified.	2022-01-20 14:55:29 +09:00
Bill Currie	e133de8c89	[gamecode] Drop B addressing for lea ... When creating the tests for lea, I noticed that B was yet another simple assign, so I decided it was best to drop it and move E into its place (freeing up another instruction).	2022-01-15 16:27:46 +09:00
