ISSOtm d9003f633a Allow the CMake user to provide their own version string 
This will be useful for downstream packagers, as well as rgbds-live
 2026-08-15 20:25:35 +02:00
ISSOtm cda77721d4 Avoid assuming that RGBDS is the root CMakeLists 
This breaks rgbds-live building us as a subproject, for example

Rangi 0c772ea049 Update external testing CI with libbet's new way of running Python 
libbet now uses `py -3` if the `py` binary exists, instead of if
`COMSPEC` is defined. So we don't need to `unset COMSPEC`, we just
need to avoid Windows' `py` launcher from being in Cygwin's `PATH`.

It turns out that `C:\cygwin\bin\env.exe CYGWIN_NOWINPATH=1 ...`
was not effectively preventing Windows' `PATH` from being inherited
by Cygwin's `PATH`, because to take effect it needs to run Cygwin's
`/etc/profile` script. The simple way to do that is using a login
shell. So we don't need the `PREFIX`/`--prefix` from the previous
commit after all.

Rangi 6f64fd00f6 Fix CI testing of installing RGBDS on Cygwin (#2038) 
We need to pass `-e` to Cygwin `bash` explicitly, since specifying
it as the non-default `shell:` no longer automatically adds `-e`
behavior to `run` blocks.

We also need to install to `/usr/bin` (which `cygwin-install-action`
automatically adds to the `PATH`), not `/usr/local/bin` (which is not
in the default `PATH`). This tests our `PREFIX`/`--prefix` handling.

Rangi 70d8d67ffc Run external tests for FreeBSD (#2035) 
This requires aliasing `make` to `gmake` and `python` to `python3`

Rangi 80c8e77b19 Fixed-point FMOD and LOG explicitly return 0 for some invalid inputs 
This is consistent with `fix_Div`'s explicit error handling,
and does not rely on subtle C/C++ `fmod` or `log` IEEE 754 behavior.

Rangi 604c69e048 Fix palette-packing decant logic to avoid UB from invalid iterator (#2031) 
The "Iterate through the component's color sets, and transfer them"
logic shifted `from.begin()`, which would make subsequent `std::advance`
calls go past `_assigned.end()` and cause UB. This rewrite uses absolute
numeric indexes into `_assigned` to avoid that potential problem.

I haven't been able to craft a test case that actually *reaches*
that piece of logic, and I suspect that it's unreachable given how
we sort and process color sets before decanting, but cannot prove
that; so it stays in. (Maybe if we added 4bpp 16-colors-per-palette
support, it would become reachable?)

Rangi b0948566bb Fail-safe treat 16-bit alignment as a fixed address even in RGBLINK

`getPlacement` to infinitely loop.
