SDCC4 partially buggy, allow per-project SDCC version #25

Open cpcitor opened 1 year ago

cpcitor commented 1 year ago

Situation

SDCC 4.0, 4.1 and 4.2 are out. They work for some projects but they have bugs. For example, SDCC 4.0 through 4.2 generate incorrect ASM on config screen of https://github.com/cpcitor/color-flood-for-amstrad-cpc .

Action

I reverted the commits advancing past SDCC3.9 to fix the regression.

TODO

Allow projects to choose their SDCC version by project configuration.
Projects without explicit configuration will get latest SDCC 3 for compatibility.
Decide if new projects will get a non-SDCC3 configuration.
Separately, write tests for bugs affecting CPC projects, report bugs to SDCC team.
