this data already exists in the big pattern match, a nice way (possibly just by convention?) to get at this would be handy.
{ lda @STA_ZPX }
perhaps it could just be a macro where you pass it a dummy instruction and allow it to infer as normal
{ lda @(infer {sta $20 x}) }
?
Preferably preserving the location in the source as well.
nesting only works in a few cases
This instruction cannot appear at the end of a page.
should fast-forward the assembler pointer to the nearest place divisible by n
eg
(align 256)
:table (data 1 2 3)
When attempting to run Asi64 on macs, getting:
shell-execute: unsupported on this platform
branching can only go 127 bytes
it would also be useful to warn if assembling over the top of somewhere already been assembled to
at the moment, passing the same name labels to the emulator confuses it. Adjust labels to make them unique when writing the label file
Given some 6502 block, the macro should count how many cycles the code takes based on the opcodes / addressing modes used.
This is a development tool to assist in cycle counting
%1111_0000 would be nice.
could do this for hex and decimal as well, but I don't think there's much point,
