Virgil Dupras	440ea43a88	z80a: make mnemonic names more uniform across assemblers ... Initially, I used the same letters as those used in the z80 ref docs, but it makes the different assemblers harder to use than they should. Having consistent "argtype" rules across assemblers should help.	2020-06-27 22:01:56 -04:00
Virgil Dupras	dbd283758c	Refer to BOOT and (uflw) by addr in stable ABI ... Was previously referred to by name+find, which was wasteful.	2020-06-21 11:41:10 -04:00
Virgil Dupras	035532acf7	z80: remove remaining indirections in execute calls ... We now have a stable ABI that is pretty cleared up...	2020-06-18 07:50:20 -04:00
Virgil Dupras	42818d25be	z80: remove layers of indirection of find calls	2020-06-18 07:40:20 -04:00
Virgil Dupras	40f92b9bab	z80: optimize chkPS ... Inline it in next and make chkPS, call a newly reserved label for it directly, removing a layer of indirection. This frees a spot in the stable ABI.	2020-06-14 09:48:10 -04:00
Virgil Dupras	31095bc04d	z80: remove call indirections in tight spots	2020-06-14 09:29:34 -04:00
Virgil Dupras	f6ded7712e	VE: add 't' ... This is the first commit I do entirely in VE. It's a habit I'm planning on taking as it helps a lot to find usability issues.	2020-06-11 18:12:01 -04:00
Virgil Dupras	d041b91846	Optimize chkPS ... Use EXX instead of the stack for HL protection and remove all spurious uses of chkPS, I wanted to inline chkPS in next because of its "tight loop" status, but for reasons I don't understand, doing so breaks Collapse OS. Later...	2020-05-22 23:12:03 -04:00
Virgil Dupras	da371451cc	Replace INITIAL_SP with PS_ADDR conf ... Now I struggle to remember why I ever did things they way I did. There must have been a reason...	2020-05-11 21:08:24 -04:00
