I present myself with a brief bio with future updates on me and what I'm creating inspired by the collapses OS and a retro post-apocalyptic life scene with the passion of old cyberpunk technology and old arcade games ...
I thank all the boys and girls who will follow me along this path, hoping to succeed in attracting the people's help.
this is a merit-based and not-for-profit ideal despite the fact that I would like to give birth to Zdos.
know ... in life I know many things ... but certainly not in this sector!
look for me and ask me friendship in instagram, my nick is 13override
all good to everyone
thanks
* Fix for tools/zasm.sh being dependent on readlink -f (an issue on macOS, preventing builds)
* Wrap zasm.sh shebang in /usr/bin/env ; remove comment about BSDs
* Optimised intoXX functions
Rewrote intoXX functions to mainly rely on intoHL, as the HL instructions are smaller and faster. Also removed some redundant push and pop instructions. I edited the given unit tests to test these, and they seem to work as expected.
* Doesn't use self-modifying code
The number of bytes is the same as my previous attempt, with 11 more cycles in intoHL, so although I don't feel as clever this time it's still a good optimisation. I found an equivalent method for intoDE, however relying on intoHL still allows for `ex (sp), hl` to be used in intoIX, which is smaller and faster.
* Update core.asm
* Tried harder to follow coding convention
Added tabs between mnemonics and operands, and replaced a new line I accidentally removed.
I've tested RAM usage when self-assembling and there weren't as high
as I thought. zasm's defaults now use less than 0x1800 bytes of RAM,
making it possible, theoretically for now, for a Sega Master System
to assemble Collapse OS from within itself.
Yup, that's ultimately why I've just made this whole big zasm
refactoring in the previous commits. To allow for this.
But also, zasm is in much better shape now...
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.
