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

Rangi 8bf5957c83 Fix RGBLINK assertion failure when -s and -c invalidly match (#2109) 2026-09-18 01:34:14 +02:00
ISSOtm f234796428 Avoid allocating for our linkdef names (#2111) 
This reverts a change introduced in fd78a9ae8, though it wasn't that commit's main point
so I'm feeling okay with undoing that.

This feels like an overkill change, using a static string is good enough for this
since we never modify this. I have considered using `string_view` instead, to have
the best of both worlds, but that's not NUL-terminated so our print functions
get a little grumpy.

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 b9b5c9a2b4 Avoid reporting redundant errors on too-large fixed sect addr 
This would happen for any such section of non-zero size.

Rangi aa657cd481 Make array buffers for snprintf just large enough for their uint32_t and uint16_t types 
Note that `bank` can store 9 bytes (8 digits plus NUL terminator)
even though `section.bank` should never go above 16-bit (4 digits).

ISSOtm 9f175f7923 Use SectionTypeInfo struct member functions for section type info 2026-09-17 09:33:21 -04:00
Rangi 589616338f Remove redundant conditional check (#2099) 
If `nbBanks > 1` is true, then `sectionTypeInfo[type].firstBank !=
sectionTypeInfo[type].lastBank` must also be true, so checking
whether either is true is unnecessary.

(On the other hand, if `nbBanks == 1`, then we might still have
`sectionTypeInfo[type].firstBank != sectionTypeInfo[type].lastBank`,
since only one of many valid banks for `type` could be in use.)

Rangi febdf63896 Fix invalid UTF-8 byte $E2 at the end of a symbol name reading past the string's end (#2092) 
This is only possible in an invalid object file, but we do have other safety checks for those.

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.

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.
