Eldred Habert afe1f01d00 Fix linker script align 16 in floating address context (#2115) 
Turns out we were just using the wrong var lmao

ISSOtm 6f69867d04 Make more RGBLINK tests use at-files 
Less special handling = good

Possibly this can be done to more tests, but this is what I found.

ISSOtm 960f82126f Fix to actually allow one-past-the-end zero-sized sections in linker scripts 2026-09-17 10:19:47 -04:00
ISSOtm e39dbe1752 Remove no-op in link test script 
No, `printf` does not do that.
This works because making it read from stdin suppresses
any words after the first one.

Rangi 7746ddbf2b Fix reverse-graphics check for whether the tilemap references too-high tile IDs in bank 1 (#2086) 2026-09-14 10:26:57 -04:00
Rangi f8a1da71c1 Only sort generated palette colors by PLTE order for indexed PNG images 
Non-indexed images can still have a PLTE chunk. We should use
`sortRgb` instead of `sortIndexed` for them, since their pixels' colors
may not all be present in the PLTE chunk and would be unsortable.

ISSOtm 9d69a08909 Determine the number of fetch/clone jobs ourselves 
Apparently our CI has some versions of Git too old to support zero to mean that.
 2026-09-11 16:31:19 -04:00
ISSOtm 970bb84450 Fix updating ext-test repos from existing copies 
The current setup fails with a "cannot read tree" error.

Also added flags to parallelise each fetch, which is relevant when submodules
are involved. (So, pretty much just starter-kit, haha.)
It would be nice to also parallelise the various fetches, but that would hit
the same remote multiple times, and could lead to rate-limiting...

Max Freedom Pollard 631ef003e7 Avoid signed overflow in RGBLINK's +, -, and * (#2060) 
RGBASM computes these with unsigned arithmetic and casts back, since
signed overflow is UB in C++, but RGBLINK's RPN evaluator used `int32_t`
directly, so `src/link/patch.cpp` tripped UBSan on lines 117, 121, and
124. Share the three operators through `opmath.cpp` so both evaluators
stay in step.

Rangi a2c52caca2 Disallow NUL characters in section names and assertion messages 
Allowing these in object files would lose anything after the '\0'
when RGBLINK reads the object.

Rangi e7e671b249 Update external test commits 2026-08-01 11:24:42 -04:00
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.
