Connor Olding d560f47be9 unfudge LI/LA a little 2015-11-22 13:49:06 -08:00
Connor Olding 009d7080a4 use proper instruction type names 2015-11-22 13:49:05 -08:00
Connor Olding 6fc3b8f2b5 add reg# register aliases 2015-11-22 13:49:03 -08:00
Connor Olding 4a6c7c4d09 pseudo-instruction crap 2015-11-22 13:49:01 -08:00
Connor Olding 57ca41d414 various 
fix jump and branch destinations.
note: branching is no longer compatible with CajeASM.

make LUI dumb: only use 'UPPER' with LI/LA.
note: this is very incompatible with CajeASM.
add LUUI pseudo-instruction to use 'UPPER' instead of 'LOWER'.

fix SUBI/SUBIU parsing.

fix LI for values under 0x10000.

pass filename through main().
tell Lexer our filename.
don't print filename in Dumper since it's irrelevant.
 2015-11-22 13:48:59 -08:00
Connor Olding 327f38cbbc implement LI and LA 2015-11-22 13:48:58 -08:00
Connor Olding b3e481301e various 
alias ZERO register to R0.
lex decimal numbers properly.
lex octal and negative numbers.
lex directives properly.
fix byte dumping.
fix UPPER behavior...?
 2015-11-22 13:48:56 -08:00
Connor Olding d5dd709cb0 new dumper to support directives 
the old one could still have a place,
with its simplicity and speed.
also, screw versioning.
 2015-11-22 13:48:55 -08:00
Connor Olding e3f882f986 simplify size handling 2015-11-22 13:48:54 -08:00
Connor Olding 724e044288 define formats in the instruction table 
this greatly reduces code bloat,
and made it easier to implement a few instructions.
everything is still very untested, however.
 2015-11-22 13:48:52 -08:00
