Virgil Dupras 7cdc288ef2 zasm: print progress indicator while assembling 2019-06-19 11:42:39 -04:00
Virgil Dupras 6516ff7212 zasm: add support for "XOR n" and "SLA r" 2019-06-18 14:24:43 -04:00

Virgil Dupras 3e7d181d3c zasm: properly raise error on bas ioPutC calls 2019-06-15 20:01:17 -04:00
Virgil Dupras 4327153ffd zasm: fix include EOF detection 
That was an interesting bug. It didn't cause a problem in emulation, but
in an RC2014 on an SD card, an include that didn't end with two newlines
would cause an infinite loop.

Virgil Dupras 92a04f4627 sdc: support 24-bit addressing 
Needed if we want to compile the kernel and zasm from within a SD card.
I didn't go straight for 32-bit because it was significantly more
complex and 24-bit give us 16M. Enough to go on for a while...

Virgil Dupras e7c07cdd9a apps/at28w: fix argument byte order 2019-06-14 21:11:45 -04:00
Virgil Dupras 93981e00eb zasm: fix include line no in error reports 
Weren't properly saved during local pass back and forth.

Virgil Dupras c613f7b0ee recipes/rc2014/eeprom: fix broken a28w args passing 
That's why the command seemed slow! It's much faster than I thought.
 2019-06-14 16:30:01 -04:00
Virgil Dupras 817636242a Add at28w app and recipe 
This allows us to write to an AT28 EEPROM from within collapse os.

Virgil Dupras 145b48efb7 Add apps/sdct 
A new app to stress test the SD card driver. Also, accompanying this
commit, changes solidifying the SD card driver so that stress tests
actually pass :)

Virgil Dupras c18d42f08b fs: further adjust to previous blkdev refactoring 
Previous refacoring broke all seek/tell within fs. fs handles now lost
the responsibility to keep track of current position. It's blkdev's job.
 2019-06-04 20:45:01 -04:00
Virgil Dupras ae028e3a86 blockdev: make implementors "random access" 
This huge refactoring remove the Seek and Tell routine from blockdev
implementation requirements and change GetC and PutC's API so that they
take an address to read and write (through HL/DE) at each call.

The "PTR" approach in blockdev implementation was very redundant from
device to device and it made more sense to generalize. It's possible
that future device aren't "random access", but we'll be able to add more
device types later.

Another important change in this commit is that the "blockdev handle" is
now opaque. Previously, consumers of the API would happily call routines
directly from one of the 4 offsets. We can't do that any more. This
makes the API more solid for future improvements.

This change forced me to change a lot of things in fs, but overall,
things are now simpler. No more `FS_PTR`: the "device handle" now holds
the active pointer.

Lots, lots of changes, but it also feels a lot cleaner and solid.

Virgil Dupras 465da6a79d zasm: add .out directive 2019-06-03 11:13:31 -04:00
Virgil Dupras 04bf2117b2 tools/emul: re-organize .h files 
What used to be `tools/emul/user.h` was in fact specific to zasm, so I
moved it there.

To avoid name confusion, I renamed what used to be kernel.h and user.h
to kernel-bin.h and user-bin.h.

Virgil Dupras af2c561c6b zasm: begin erroring out reliably 
Up until now, invalid source input had undefined behavior. We're now
beginning to define that behavior so that zasm can be a bit more usable.

Virgil Dupras 976a93971c zasm: improve docs 2019-05-27 10:38:29 -04:00
Virgil Dupras c40bc329d5 zasm: fix expr returning wrong values on first pass 
To run a parseExpr on first pass would always return a false success
with dummy value because symbols are configured to always succeed on
first pass. This would make expressions like ".fill 0x38-$" so bad
things to labels because "0x38-$" wouldn't return the same thing on
first and second pass.

Revert to parsing literals and symbols after having scanned for
expressions and add a special case specifically for char literals (which
is why we scanned for literals and symbols first in the first place).
 2019-05-20 10:46:27 -04:00
Virgil Dupras e18f9b53a9 zasm: add support for "$" symbol

Virgil Dupras bc1496a7e3 zasm emul: bring back kernel/user distinction 
It was a bad idea to remove it. Now that I'm introducing the concept of
a per-app glue file, it becomes much easier to build emulated zasm as a
userspace app.
 2019-05-19 12:57:59 -04:00
Virgil Dupras 7fad3b0c90 Move /parts/z80 to /kernel 
Let go of that "meta os" thing. it's not as meta as I made it sound
like. It's a kernel.

Virgil Dupras 98695f9912 zasm: de-index symRegister 
Make symRegister's logic pointer-based so we can break through the 0x100
limit.
 2019-05-19 09:06:24 -04:00
Virgil Dupras c01816b055 zasm: make instr a bit more zasm-friendly 
But we're still at a certain distance from assembling it with zasm:
we're busting the 0x100 symbol limit.

Virgil Dupras 22c7eeaa5d Move apps/zasm/tests to tools/tests/zasm 
This 'apps' folder is going to disappear. Everything is going to be a

Virgil Dupras 0ae91e55ec zasm: big local symbols overhaul 2019-05-16 08:26:00 -04:00
Virgil Dupras e9244b80ee zasm: big I/O overhaul 
Instead of buffering input in memory one line at a time, we go in "just
in time" mode and always read contents directly from I/O, without
buffering.

It forces us to implement a `ioPutback` scheme, but on the other hand it
greatly simplifies cases where multiple tokens are on the same line
(when a label is directly followed by an instruction).

The end result feels much more solid and less hackish.
