Rangi b4988afc8a Fix RGBLINK ignoring alignment constraints when placing empty sections 
Fixes #2095
 2026-09-17 11:16:18 -04:00
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.

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 5869e0dc60 Fix RGBLINK scrambling algorithm to work for SRAM 
Since SRAM sections start from 0, we had been using a signed
`int8_t curScrambleSRAM` counter to allow 0 as a scrambled bank,
but this actually just placed all floating SRAM sections in bank 0.

Rangi 996469ee28 Ensure CRLF line endings are preserved when necessary 
Some test cases need CRLF line endings checked out even on Unix.
Also some source files had inadvertently contained CR bytes.

Rangi42 1fdeb34e50 Fix too-short .out.bin expected test results 
RGBASM tests now use `rgblink -x` instead of `dd` to get trimmed
test output. RGBLINK tests cannot do so because some of them
(e.g. bank-numbers.asm and sizeof-startof.asm) rely on ROMX
sections above 1, and `-x` implies `-t` which breaks that.
