Connor Olding e1ae1fdd64 optimize incbin via string passthru 2016-11-23 12:22:31 -08:00
Connor Olding cdc0f8edb2 add a barebones expression parser 
at the moment, this probably only works in directives.
some of the operators are still unimplemented, and the errors are poor.
there will be support for accessing variables in the future.

Connor Olding 693294bef2 fix labels and variables in data directives 2016-04-24 04:41:30 -07:00
Connor Olding f851540b24 various fixes, mostly for labels 
reimplement modulo by 0x80000000 for labels.
allow numeric label values ("REL") to be "fixed" to bypass label calculation.
add offsets after label calculation instead of before.
properly check for EOL after all expected arguments have been exhausted.
finally, add token properties to debug dumps.

Connor Olding 54f28dc333 don't strip 0x80 prefix from .ORG addresses 
the rest of the code seems to handle this fine,
since setting options.offset was bypassing it anyway

Connor Olding fffe542d10 fix most line numbers in errors 
this might be a bit of a hack;
i feel like nextc() should always happen after yield(),
not a mix of before and after.
