7903c14993 Fix undefined behavior when reading constant in RGBLINK 2020-02-07 14:51:26 +01:00
ISSOtm
a7cb0a166a Inline readRGBxObject 
This was made separate with the intention of supporting multiple versions,
but after some discussion this was decided against, so better improve
readability instead.

f2be601a13 Check "left" boundary as well in isLocationSuitable 
"fixed" and "aligned" location checking advanced the target location to places
regardless of the associated free space, potentially breaking the assumption
that the location was always further in memory than the free space's base.

Rather than adding more code to try keeping that assumption true, harden
`isLocationSuitable` and handle that case as well.

50f091ab7c Fix RGBLINK failing to read args on certain machines 
`char` has implementation-defined signedness, and if it's chosen to be unsigned,
then -1 gets converted to 255, which is then promoted back to `int` as... 255,
always failing the loop condition in src/link/main.c:118
`int8_t` has the correct signedness, but considering `musl_getopt_long_only`
returns `int`, better use that so as not to lose any bits

71fe652556 Allow ROMX and WRAMX sections in restricted modes 
Closes #462, although with this implementation `BANK("some ROMX section")` would
return 0 instead of 1, which I think is benign anyways

ceae4a44f3 Stop using f(un)?lockfile 
Those are only useful for locking file IO across threads, but RGBLINK is
single-threaded anyways, so they don't matter. Plus, they aren't provided by
mingw, so that'll remove part of the problem
