Virgil Dupras d6c9ab3f32 tools/stripfc: strip a little bit more 2020-04-12 12:47:50 -04:00

Virgil Dupras e37f4c2551 bin2c: add missing stdtypes.h 2020-04-07 18:13:42 -04:00
Byron A. Grobe 217df20d77
Moved tools/bin2c to single-level with other tools. 2020-04-07 16:56:55 -05:00
Byron A. Grobe f65c189e9b
Replace bin2c.sh with a more portable implementation. 
`xxd' is not available on all systems, and on others does not support
the `-i' flag. Since bin2c.sh relied on a tool that I can't seem to find
a compatible version of, I have included a simple, portable replacement in C.

Usage remains the same:
bin2c ARRAYNAME < inputfile > outputfile.

This change is also reflected in emul/Makefile.

To update LATEST offset more easily. Will be useful for recipes.

Virgil Dupras 049f2cf222 Reverse ttysafe escaping order 
Sending the escape after its target made things complicated for upcoming
stuff I want to add. Although it makes `recv.asm` slightly larger, it's really
worth it.

Virgil Dupras c5116b39ae Fix tools Makefile for GNU make 
It seems that my little "@.c" trick only worked in BSD make...

Also, removed leftover in runbin.c (what did it do there??) that
could result in tests falsely passing.

Virgil Dupras 7ca54d179d lib/expr: make EXPR_PARSE "tail" HL 
Things are now much simpler.

Virgil Dupras 289037a3dd lib/parse: make parseDecimal "tail" HL 
HL, instead of being preserved, is set to the character following
the last read character.

Virgil Dupras dcb96aefe9 lib/parse: remove parseHexPair 
Also, make parseHexadecimal "tail" (HL). Soon, all routines in lib/parse
will do that, making the life of lib/expr easier.

Virgil Dupras 213614af33 lib/expr: make recursion process a bit more orderly 
Instead of going left and right, finding operators chars and replacing them
with nulls, we parse expressions in a more orderly manner, one chunk at a
time. I think it qualifies as "recursive descent", but I'm not sure.

This allows us to preserve the string we parse and should also make the
implementation of parens much easier.

Virgil Dupras 7410891ad1 lib/expr: fix unary minus 
For some reason, I've mistakenly disabled tests in test_expr without noticing
and I also broke "-123" parsing. Fixed.

Virgil Dupras aef96c5e96 Add missing common.asm test harness file 2019-12-23 16:02:26 -05:00
Virgil Dupras a034f63e23 test: begin adding common test harnessing code 
This should make tests a bit more convenient to write and debug.

Moreover, begin de de-IX-ization of parseExpr. I have, in a local WIP, a
parseExpr implemented using a recursive descent algo, it passes all tests, but
it unfortunately assembles a faulty zasm. I have to find the expressions that
it doesn't parse properly.

But before I do that, I prefer to commit these significant improvements I've
been making to tests harness in parallel of this development.

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 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.

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.
