Rangi 824ebd80f9 Use [[fallthrough]]; attribute instead of // fallthrough comment 2026-07-08 16:30:52 -04:00
Rangi ed8e3e4d02 Reset errno = 0 before parseWholeNumber calls and errno == ERANGE checks 2026-07-07 17:02:46 -04:00
Rangi 21682e8814 Consistently handle negative shifted macro args (#2014)
Negative macro arguments count from the end, i.e. `\<-1>`
is equivalent to `\<_NARG>`, even after `shift`ing them.

Negative arguments cannot be used to access shifted values.

Rangi f82b0838a1 Disallow minus sign before symbol name in bracketed macro arguments (#2015)
This was being silently allowed but without actually negating the symbol's value

Rangi 1e4a060d9e Guard against undefined behavior in double2fix
I haven't found input which triggers any, but this is more
technically correct just in case.

Rangi fe3b238dea Do not allow defining labels outside sections (#2013)
Creating a `Symbol` with `type = SYM_LABEL` but `section = nullptr`
is inconsistent and dangerous. I was not able to cause any buggy
behavior so far, but it's safer and reasonable to not create such
a symbol in the first place.

The main consequence is that `DEF(LabelOutsideSection)` will now
evaluate as 0.

Rangi 46a6966b70 Fix $8000_0000 % -1 to warn with -Wdiv like $8000_0000 / -1 does (#2012) 2026-07-06 15:08:44 -04:00

Rangi 007672f080 Intern identifier strings only after checking for keywords 2026-05-25 23:55:57 -04:00
Rangi 55db252a8f Simplify the lexer by removing BufferedContent and inlining ViewedContent (#1981)
Instead of reading 64 characters at a time into a rolling buffer
as `shiftChar()` is called, we read 8192 characters at a time into
a complete buffer before any `peek()`/`shiftChar()` operations.

Rangi ef2f021892 Simplify sectError handling, without the need for an empty-string sentinel
The `errorNoTrace` case for the empty-string sentinel was unreachable,
so we can just have a `fatalNoTrace` error right away.

Rangi 728bed39d5 Do not support GCC 9 (#1978)
This will let us use C++20 features that GCC 9's experimental
C++20 support did not yet cover, such as "concepts".

- Naming convention of "`std::deque<> *Stack`" when relying on
  `.push_front()` and `.pop_back()`

Rangi cfec017fed Consolidate, refactor, and bugfix the lexer's handling of captures and skips (#1957)
- Do not error about local labels following keywords in skips or captures (fixes #1955)
- Do not incompletely attempt to handle line continuations in skips (fixes #1956)
- Rename `skipToLeadingIdentifier` to `skipToLeadingKeyword`, refactor to merge
  `skipToEOL` into it, and use it for both skips and captures

Rangi eb9e9c0f33 Replace charmaps' fixed-size 256-value array with a vector of pairs
This should save memory at the cost of O(n) instead of O(1) access,
which should be okay because the `next` vector is generally small.
