Virgil Dupras d4cdb659b4 tools: add blkpack 2020-04-13 22:05:03 -04:00
Virgil Dupras 7292d486dc z80a: add stuctured flow words 
Allow us to rely a little less on labels. We now only need 4.

Virgil Dupras 7d184b9e70 Use SUBHLss, macro more 2020-04-13 19:31:23 -04:00
Virgil Dupras d919a10265 Remove runbin 
It's not used

Virgil Dupras b536d3bfd6 rc2014: complete the EEPROM recipe 2020-04-13 14:41:02 -04:00
Virgil Dupras d0545d555f upload: use A! instead of C! 
It makes the tool much more versatile. I'll have adev being included
in all recipes, so it can be assumed.

Virgil Dupras d08a9711c5 boot: make HERE point to RAMEND instead of CURRENT 
The former was only used in the peculiar context of "/emul". The
regular case is actually HERE pointing to RAMEND on boot.

Virgil Dupras 76e4422796 Add adev unit 2020-04-12 21:49:20 -04:00
Virgil Dupras d996dd8c9e Add one layer of indirection in subsystem memory management 
This allows optional subsystems to not needlessly reserve too much
system memory and it also reduces offsets bookkeeping.

Virgil Dupras d4f65911c0 rc2014: add notes about stage3.bin 2020-04-12 14:15:06 -04:00
Virgil Dupras 420836276d readln: rename (c<) to (rdln<) 
so that it isn't picked up automatically at boot. Only when (c<$) is
called do we override (c<). This fixes tricky boot problems.

Virgil Dupras c515720e23 Revert "Remove link.fs" 
Let's revisit the relinking approach, with LITA this time.
This reverts commit 6652125d47.

Virgil Dupras 3822182226 xcomp: shrink scope 
It seems that xcomp can't manage to reliably compile core+ units.
Let's limit the role of xcomp to z80c+icore.

I'm getting a little desperate here. I'll revisit the link.fs approach
with a new idea I had...
 2020-04-11 11:38:45 -04:00
Virgil Dupras 6368cc3bac Remove (sysv) 
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

Virgil Dupras a6efb65010 emul: extract capture mark from icore into xstop.fs 2020-04-10 14:16:45 -04:00
Virgil Dupras f62376bd0a boot: remove _bend 
It's not needed anymore now that the boot binary is built in one pass.
 2020-04-10 09:59:45 -04:00
Virgil Dupras 7aa1be070b emul: build boot binary in one pass 
... instead of building boot.fs, and then z80c.fs/icore.fs in separate
passes. This strengten xcomp by making it support 2 completely separate
dicts (that is, the X dict is *not* connected to the system dict. The chain
now stops at EXIT def in boot.fs).
 2020-04-10 09:55:58 -04:00
Virgil Dupras c8c337fd58 xcomp: widen scope 
We can now cross-compile core.fs.

Virgil Dupras 54929c2aa0 xcomp: simplify further 2020-04-09 12:10:43 -04:00

Virgil Dupras f1171c656c xcomp: make (xfind) use _find instead of (find) 2020-04-09 11:24:43 -04:00
Virgil Dupras 1b6286dcfe Make (find) 2-layered, the lower layer having CURRENT as a param 2020-04-09 11:20:54 -04:00
Virgil Dupras 66dc621919 xcomp: don't automatically shadow core words 2020-04-09 09:43:48 -04:00
Virgil Dupras 0c3067ed9a icore: simplify definition of ":" and ";" 2020-04-09 09:38:59 -04:00
Virgil Dupras 784b109652 So, why was ":" an immediate again? 2020-04-09 09:27:51 -04:00
Virgil Dupras afed423530 Remove memory maps 
It was a dead end. my new tentative solution is xcomp.

Virgil Dupras 6f082b0b13 Change DELW signature 2020-04-09 08:26:27 -04:00
Virgil Dupras 68f359d6c2 Add xcomp unit for cross compilation 
Memory mapping is a dead end too, solution has to be at a higher
level. xcomp is my new approach.

Virgil Dupras b5638d142a Add word "DELW" 2020-04-08 20:40:23 -04:00
Virgil Dupras 2a2e3a64a4 Move IMMED? from z80c to icore 2020-04-08 20:09:32 -04:00
Virgil Dupras a7a2f3d08b Move IMMEDIATE from z80c to core 
This makes IMMEDIATE affected by memory mappings.
 2020-04-08 19:43:44 -04:00
Virgil Dupras 64e441d059 Move SCPY from z80c to icore 
This way, it can be affected by memory mappers.
