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 64935d8b40 avra: add IN and OUT instructions 2019-12-15 08:43:59 -05:00
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 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.
 2019-12-13 09:56:23 -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.
