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 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 40a756cf1c Move a bunch of words from XPACKed core to xcomp core 2020-05-14 08:18:53 -04:00

Virgil Dupras bb77cd0759 xcomp: add overrides into a loadable block
Makes xcomp.fs units shorter.

Virgil Dupras 7c20501f27 Move core's blk to xcomp core (low and high)
TODO: implement X['] so that I can remove those XCURRENT patterns.

Virgil Dupras 029df00ad4 Free some space for xcomp core 2020-05-13 09:11:57 -04:00
Virgil Dupras d6a3e79394 Free some space for xcomp core low 2020-05-13 08:00:49 -04:00
Virgil Dupras cbf5baf3b6 Pack core words a bit
This leaves space for xcomp-core which is growing.

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.

Virgil Dupras 44b065ff99 ti84: unify drivers
No more low/high

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...

Virgil Dupras 2791dd992e ti84: offset binary by 0x100 to free space for TI-specific stuff
Not yet tried on real hardware, but we should be getting pretty
close...

Virgil Dupras 06a4674317 ti84: implement a-lock
There's a bug where the first char after a-lock isn't a-modded. I
have troubles figuring it out for now. It feels like deja vu. I
think I had the same problem with asm.

Virgil Dupras 2f1e635b9d ti84: tidy up driver code
Pushed all words directly interfacing with ports and memory offsets to
low level layers. This saves us the need for keeping those variables in
runtime memory.

Virgil Dupras afc2327770 Split icore in 2 parts
The goal is to insert device drivers in between.

On the emulator of course...

Virgil Dupras 58ec54fc97 ti84: wip
Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.
