Virgil Dupras 14fbfa2967 avra: small _parseArgs refactoring 
Take argspec pairs directly as an argument instead of taking a
pointer to an argspec pair.

Virgil Dupras 62eb5589c3 avra: refactor instruction tbl 
The instruction table is now beefier and has redundant data, but
this simplifies processing. This should simplify upcoming work.
 2019-12-15 15:53:28 -05:00
Virgil Dupras aa8df95f7d Add "avr/" includes folder 
Also, add a "real world" example in AVRA tests, a blink program on
a ATtiny45. Some instructions are commented out because they aren't
implemented yet, but not many.

The output of the program has been verified against AVRA's own
output.

Virgil Dupras ab578159b7 avra: refactor args parsing 
This costs us a bit of space for now but should make things a lot
simpler down the road, especially with "alias ops" which are simple
syntactic sugar for another op.

Virgil Dupras 33c480a5dd avra: remove useless instrBRBits table 
I had written this when trying different approaches to adding BR and
I forgot to remove it.

Virgil Dupras e691dab070 zasm: little drive-by optimization 
Use IX directly for argspec rows instead of going through DE. It saves a bit
of processing. The code was this way because I initially didn't use IX at all,
so as code evolved, that DE translation stayed as an artifact.

Virgil Dupras 0d7693a163 core: remove writeHLinDE 
It wasn't used much so I inlined it.

James Stanley 1b8b113536 Fix filesystem in shell emulator 
We now treat the block device as fixed-size rather than trying to grow it in response
to kernel activity.

Previously, if you tried to create 2 files in a row, only the first 1 would actually appear,
because the device only ever got larger when a byte was written immediately past the end of
the device.

Now we just let the kernel write bytes to the disk anywhere, so new files can be created even
when the previous file is not completely full.

Also, fix buffer overrun in reading filesystem image, and use a more idiomatic fgetc loop.

Virgil Dupras 948a06cb41 tools/tests: add missing doc about shell tests 2019-12-12 16:31:52 -05:00
Virgil Dupras 4f7a05e3b7 core: remove cpHLDE 
It wasn't used much, so I replaced its use in the kernel with direct code
and moved the routine in apps/ed, the only other place where it was used.

Virgil Dupras c002c69208 Include tools/tests/shell/test.cfs in repo 
The order in which cfspack includes its file depend on the platform. To have
tests that reliably pass, test.cfs has to be committed in.

Virgil Dupras 5b155a5c15 tools: use BASIC's new while loop 
Also, increase STDIO_BUFSIZE to 0x40 so that those while loops work.

Virgil Dupras 7907687abf tools/uploadb: make it much much faster 
By uploading a BASIC loop and then run it, we can reduce the serial
communication to pure content which greatly reduces the overhead and make
the process much much faster.

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 8ff4b18c51 tools: add memdumpb 
In C this time. Python/Perl code is barely terser than C for these little
tools. Why bother with interpreted?
