Virgil Dupras d9db0a824e Make makefiles and shell scripts portable 
It's no longer required to use `gmake` under OpenBSD and shell scripts
no longer require bash.

Virgil Dupras 0e79035d9c Disable test failing on Travis 2019-11-13 22:37:00 -05:00
Virgil Dupras 82995eb346 zasm: have .fill generate an error on overflow 
Can possibly avoid a lot of debugging pain.

Virgil Dupras 1ae51bea3a tests: remove instr blacklist 
Because scas isn't used as a reference anymore, no need to blacklist its bugs
anymore.

Virgil Dupras 5f6b303e75 zasm: add IX/IY support to SRL, RR and RL 2019-11-10 22:03:18 -05:00
Virgil Dupras b745f49186 Rename blockdev's API routines to GetB/PutB 
The goal is to avoid mixing those routines with "character devices"
(acia, vpd, kbd) which aren't block devices and have routines that
have different expectations.

This is a first step to fixing #64.

Virgil Dupras 3b1bbc1751 zasm: support negative displacement for IX/IY 
Needed by #30.

Virgil Dupras 8926c33ab1 Fix tools/tests/zasm/runtests.sh shebang 
It needs bash after all. On OpenBSD, /usr/sh works, but not on Ubuntu.
 2019-10-10 15:22:21 -04:00
Virgil Dupras f4b6c7637d zasm: rename #inc to .inc 
scas, it's not needed any more.

Virgil Dupras c2d84563dd zasm: allow duplicate const definition 
This will allow interesting override scenarios, adding flexibility.

Virgil Dupras cdb206b7a5 zasm: fix nasty (iy+d) misparsing bug 
*sob*...

Virgil Dupras 311d04e9aa zasm: make symbol registry easily parametrizable 
I'm about to split the global registry in two (labels and consts)
and the previous state of registry selection made things murky.
Now it's much better.
 2019-07-22 15:13:09 -04:00
Virgil Dupras 34f499184d zasm: add ".bin" directive 
Also, remove zasm/test7 because it changes too much all time time
(whenever zasm changes) and isn't precise enough. Too much noise,
not worth it.
 2019-07-21 12:58:02 -04:00
Virgil Dupras fe15bafeca zasm: fix bug with registry selection 
During expression parsing, if a local label was parsed, it would
select the local registry and keep that selection, making
subsequent global labels register in the wrong place.

Virgil Dupras a7afbe091e tools/tests: remove scas requirement 
I'm about to break compatibility with scas. Before I do that, I
need to adjusts tests. Instead of running scas to compare results,
we commit expected result as binaries directly in the repo.
 2019-07-20 17:13:57 -04:00
Virgil Dupras 253674ea05 Fix broken tests 
Also, make tests run in a *BSD environment

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.

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 9a72f10221 zasm: includes CFS is now built on-the-fly by zasm.sh 
This makes for a much more usable zasm linux binary that doesn't have to
be rebuilt every time apps or kernel change.
 2019-06-02 19:57:40 -04:00
Virgil Dupras 22e990ed89 Parametrize zasm linux bin's include CFS file 
... instead of embedding it in the binary itself. Additionally, add a
"zasm.sh" wrapper to faciliate zasm calls on a linux machine.

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 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.

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.
