- Fixed-point formulas are implemented using IEEE-754 floating-point
internally, which could give infinity or NaN values whose conversion
to fixed-point integer was platform-dependent.
- Formatting fixed-point $8000_0000 (INT32_MIN, -2147483648) was
not putting the negative sign in front.
The Python Pillow image library gives different output for
`Image.getcolors()` in version 9 than version 10. This causes
libbet's SGB border to be built differently, giving a different
ROM hash and technically failing the test script.
This patches libbet to only keep the known-good colors. It also
adapts the coverage script to run all the tests, including
building the third-party projects.
This way, if a child context initializes `\@`, the parent won't
reset it. And if the child context did not initialize `\@`,
then resetting it would be redundant.
This allows us to control the order in which sections are iterated,
instead of it depending on the internals of `std::map`. (This order
is arbitrary, but should be deterministic regardless.)
This still doesn't allow identical exported label constants.
That can be addressed when or if it's requested for a real use case.
Symbols only store one source filename + line number, so this
arbitrarily keeps the last read symbol as the reported one.
We were not initializing some expressions, and they were using
the values of the previous expressions instead. This just so
happened to not crash the tests, and to sometimes even give valid
results (although `BANK()` of a non-label symbol being $4B4E4142,
the ASCII balue of "BANK", was something we missed).
* Avoid redirecting error messages in RGBLINK tests
We check that RGBLINK prints nothing to stdout, so all that
would be captured on stdout is a putative failure message.
* Require each RGBLINK test to check error output
Otherwise, you can have a test that just... checks nothing!
* Document how to add tests
Fixes#1300's last remaining item.
Also add `checkdiff` rules to remind us to update that doc if
any of the test driver scripts are updated.
* Replace FAMs with `std::vector`s (or one `std::string`) in four `struct`s
* Anonymous types declared in an anonymous union are also non-standard
Only Clang complains about this (-Wnested-anon-types)
