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
Connor Olding	e6d34bdb0b	only specify one instruction list	2015-11-22 13:48:51 -08:00
Connor Olding	2d8aabc311	add remaining fp instructions	2015-11-22 13:48:49 -08:00
Connor Olding	e07d3f04e8	add fp compare instructions	2015-11-22 13:48:48 -08:00
Connor Olding	5da1b19fd5	use filename in errors; fix JALR	2015-11-22 13:48:46 -08:00
Connor Olding	4646d467d2	set up as a proper module	2015-11-22 13:48:45 -08:00
Connor Olding	96a11a0114	refactor to use classes; no hardcoded stuff	2015-11-22 13:48:43 -08:00
Connor Olding	8e9ffba103	implement relative branches; fix register orders	2015-11-22 13:48:42 -08:00
Connor Olding	1b689368d8	a little cleanup	2015-11-22 13:48:41 -08:00
Connor Olding	846f611001	add basic fp arithmetic	2015-11-22 13:48:39 -08:00
Connor Olding	4c7f744dc0	add fpu registers and basic moves	2015-11-22 13:48:38 -08:00
Connor Olding	f302543b2d	recognize pseudo & fp instructions ... i hope this is all of them.	2015-11-22 13:48:36 -08:00
