Virgil Dupras 852c775b5b sms: implement linefeed in VDP 2020-05-15 16:08:27 -04:00
Virgil Dupras f9a8e6f180 sms: Pad WIP 2020-05-15 15:41:06 -04:00
Virgil Dupras 1597f1e131 Don't generalize XYPOS just yet 
It was ill-advised.
 2020-05-15 14:09:31 -04:00
Virgil Dupras db9885b8cf Rename (find) to FIND 
I hadn't noticed that this word was almost ANS compliant.

Virgil Dupras 175b4bc497 sms: CollapseOS prompt! 2020-05-15 12:46:25 -04:00
Virgil Dupras ca60685067 Streamline initialization process 
Instead of letting each configuration taking care of RDLN$ and
"CollapseOS" prompt, move this to BOOT to simplify xcomp units.

Initialization source code is now only for driver initialization.

Virgil Dupras 0163af470a Fix EOT behavior after QUIT 
Previously, calling quit would break EOT behavior and not properly
quit Collapse OS.

Virgil Dupras 43eabf566b sms: WIP ! 2020-05-14 22:15:31 -04:00
Virgil Dupras 87b51a6261 By default, allocate about 0x100 bytes for PSP+RSP 
During "make updatebootstrap", we use less than 0x20 bytes on the
PSP side and less than 0x40 bytes on the RSP one. 0x100 bytes ought
to be enough for anybody.

Virgil Dupras bf289b0a67 z80a: de-variable-ize 
Use straight VARIABLE instead of Z80MEM+. Initially, I used this
system to allow z80a to be embedded in a system binary, but now
I don't think it's worth it. Compiled, z80a is 2.5k. Sure, it's a
sizeable amount of RAM, but I think that even with it in RAM, I'll
manage a bootstrap within my most constrained machine, the SMS with
8K.

Virgil Dupras 3fbae082f4 Remove INTJUMP mechanism 
Not worth the trouble. Easier to set jump in binary directly.

Virgil Dupras e6bac985fa Cross-compiles in a single stage! 
Finally got rid of the XPACKed core and managed to cross-compile
all core words, which greatly simplifies the bootstrapping process.

Virgil Dupras 68262f925b Almost done De-XPACKing! 2020-05-14 09:58:48 -04:00
Virgil Dupras 640e3321fc Move a bunch of words from XPACKed core to xcomp core 2020-05-14 09:54:33 -04:00

Virgil Dupras 179c66be8a Move a bunch of words from XPACKed core to xcomp core 2020-05-14 08:50:43 -04:00
Virgil Dupras 74896051bb Move BOOT, (boot<) and INTEPRET to high xcomp 
Saves us an (ok) indirection and will save us more soon.

Virgil Dupras 51997533ff Move a bunch of words from XPACKed core to xcomp core 2020-05-14 07:58:55 -04:00
Virgil Dupras 80d730318a Simplify LOAD's INTERPRET exit mechanism 2020-05-13 22:55:52 -04:00
Virgil Dupras 2e9e7047bf Make INTERPRET break on ASCII EOT 
This should allow me to simplify LOAD's exit mechanism on block
end.

Virgil Dupras 052d59a3a2 TOWORD: tiny optimization 
My mind is getting forthy.
 2020-05-13 20:59:00 -04:00
Virgil Dupras 33d37d4ce9 WORD: don't overwrite RAM on words over 31 chars 
This allows me to reclaim some RAM I hadn't even noticed I
needlessly monopolise.
 2020-05-13 20:39:53 -04:00
Virgil Dupras bd1e76ec5b Gather all RC2014 drivers into a single "RC2014 Recipe section" 2020-05-13 14:56:38 -04:00
Virgil Dupras 9b85961093 Rename "Core words" to "XPACKed core" 
Now that this section is so small, I think I can see a possibility
for cross-compiling Collapse OS entirely, which would be great
because we could get rid of the relinker.
 2020-05-13 14:31:56 -04:00
Virgil Dupras 76037ca1e7 Simplify boot process 
That INIT thing is unnecessary.
 2020-05-13 14:19:54 -04:00
Virgil Dupras bb77cd0759 xcomp: add overrides into a loadable block 
Makes xcomp.fs units shorter.
 2020-05-13 13:33:24 -04:00
Virgil Dupras 0434d02818 xcomp: implement X['] 2020-05-13 13:24:58 -04:00
Virgil Dupras 7c20501f27 Move core's blk to xcomp core (low and high) 
TODO: implement X['] so that I can remove those XCURRENT patterns.
 2020-05-13 10:50:46 -04:00

Virgil Dupras 6a5ff3adcb rc2014: unify SD Card driver 
Now more low/high layers.
 2020-05-12 21:48:29 -04:00
Virgil Dupras cbf5baf3b6 Pack core words a bit 
This leaves space for xcomp-core which is growing.
 2020-05-12 21:27:06 -04:00
Virgil Dupras dfe474ca0e xcomp: add XCOMPILE and X[COMPILE] 
This allows us to move words like ABORT" to xcomp-core, which is
I think the last roadblock before being able to unify all drivers
into a single xcomp layer.
 2020-05-12 21:08:18 -04:00
Virgil Dupras 44b065ff99 ti84: unify drivers 
No more low/high
 2020-05-12 12:41:47 -04:00
Virgil Dupras 1094ec9c57 Make DO..LOOP stable 
DO and LOOP now only compile words from stable ABI, which make them
suitable for xcomp. This will greatly simplify driver writing and
allow us to mostly avoid the low/high divide in drivers.

LEAVE is still xcomp-incompatible though.

This make us very very tight for "<0x100" limit for literal words.
Hopefully, we won't need more stuff in that area of the binary...
 2020-05-12 10:40:59 -04:00
Virgil Dupras b760c2d353 SCPY: don't copy the NULL 
This makes [entry] much simpler. Also, remove unused LITS word.
 2020-05-12 07:36:20 -04:00
Virgil Dupras 231d727598 Move a few words from core to xcomp core 2020-05-12 07:21:34 -04:00
Virgil Dupras 9ad7ee7a4b Rename Inner core to Cross-compiled core 
And refreshed description.
