Virgil Dupras ecca70c7f3 Add layer of indirection to EMIT
This would allow things like temporary giving control to the *CL
line on the TRS-80. For example... A very far fetched example. Not
at all the only *raison d'etre* of the layer...

Virgil Dupras 0044011f06 Move AT28 and TRS80 drivers to higher blocknos
I'm reserving the 100-200 range for non-bootstrapping needs.

Virgil Dupras 581f04a4bc Keep stage1 bootstrap bin instead of stage 0
XPACKed source needing to be kept in bootstrap bin didn't make
much sense. With the removal of stripfc, it makes more sense to keep
the compiled form of stage 1 in repository as a bootstrap binary.

Also, rename it to forth.bin.

no floppy yet.

Virgil Dupras 1b2c4b519e icore: add BIN+
This allows us to write LATEST at proper offset in emul/stage1.fs in
cases where we set a nonzero BIN(.

Virgil Dupras fc67b88720 Make BIN( offsetted binaries closer to working at all
I have a working offset-by-0x100 stage0 now.

Virgil Dupras 61b2e02351 xcomp: remove XOFF and use ORG and BIN( instead 2020-04-28 09:37:00 -04:00
Virgil Dupras 838548843e boot: apply BIN( to stray stable ABI references
With cross compiling and IMMEDIATE words, things get icky with stable
ABI references. For the same reason that EXIT, (br) and (br?) need to
stay at stable offsets, these word references will not have BIN(
properly applied at Inner core xcomp.

The solution for now is to adjust during EXECUTE, which is ugly and
inefficient, but I don't see a better solution right now.

Virgil Dupras 4501313410 Add [IF] .. [THEN]
Will be useful as kinds of "#ifdef"s during xcomp.

Virgil Dupras 295b4b6e0a z80a: add BIN( parameter
Will be useful for assembling binaries for the TRS-80 which can't start
at addr 0.

Virgil Dupras 7c692c1111 recipes/rc2014: include readln directly in stage 1
XPACK is more efficient than stripfc was, we can pack more stuff in 8K.
We now have enough space to fit readln.

Virgil Dupras a2f164ecc3 emul: bootstrap to stage2 from within Collapse OS!
Big bootstrapping change which greatly reduces the role of the modern
operating system in the bootstrapping process.

Virgil Dupras 389b23fe1a Change C<? mechanic
It's now a simple flag updated by the C< implementation. No more
routine pointer.

The goal is to avoid tons of "ok" during a LOAD operation.

Virgil Dupras 8d78ca9dac tests: add test_sdc
The SD card driver is a bit too slow to be bearable. I'll write
_crc16 in z80 and see how it goes.

Virgil Dupras b5c370a936 emul: embed blkfs in forth binary
This will allow us to read from blkfs in tests.

Virgil Dupras 1bd191e86a Move /emul/forth/* to /emul
Less noisy this way

Virgil Dupras 816563e2e3 Stop LOADing on ABORT
This is done by adding a "C<* override" layer that is reset to 0 on
ABORT.

The problem was that when ABORT happened during a LOAD, we had a
resetted RSP and started from a clean INTERPRET, but LOAD didn't
have the opportunity to restore C<*, which caused it to continue
interpreting from the faulty BLK.

With a C<* override, we don't need to *restore* C<*, we just need to
clear the override.

Virgil Dupras af39b37dd1 Replace the "> " prompt with the more traditional "ok" one
This is more than cosmetic, it's also highly usable. The presence
or absence of the "ok" message allows us to know whether the command
aborted. Previously, the "> " prompt appeared when the system expected
a prompt in the INTERPRET context, whether the previous command aborted
or not.

Also, this allows us to get rid of that ugly FLAGS global variable.

The way is clear for complete stage1 bootstrapping on the RC2014
target!
