Rangi df0b557638 Don't allow invalid interpolations to occur (#1925) 
Fixes #1921
 2026-04-11 18:16:07 +02:00
Rangi 143d503c6c Update libpng to 1.6.56 (#1922)

to macOS-preinstalled `shasum`.

Rangi 9b4b4a581b Check for overflow in fixed-point precision suffix (#1918) 
Fixes #1917
 2026-04-07 17:06:54 -04:00
Rangi 11f6278d95 Refactor lexing of fixed-point numbers (#1915) 
This incidentally fixes a bug with too-long fixed-point literals
that have precision suffixes.
 2026-04-06 21:45:34 -04:00
Rangi ede9405daf Fix some fixed-point literal lexing issues (#1914) 
- No fractional digits are necessary after the decimal point,
  e.g. `42.` is valid instead of `42.0`
- Error messages refer to "fixed-point" not "integer" constants
- Test more carefully for lexing unrelated to underscores

Rangi 41ab5dff5a Implement [[ fragment literals ]] (#1614) 
This feature is referred to as "code/data literals" in ASMotor,

for the PDP-10. RGBASM already had the "section fragments"
feature for keeping disparate contents together when linked,
so these worked naturally as "fragment literals".
