This feature is referred to as "code/data literals" in ASMotor,
and simply as "literals" in some older assemblers like MIDAS
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".
Identify files by (device, inode), not by path, so that symlinks,
relative paths, case-insensitive paths, or other edge cases
do not result in double includes.
- The '#' component for type 's' now escapes the string characters
- The '#' component for type 'f' now prints a precision suffix
- The new 'q' component specifies a precision value
* Implement a '#' prefix for raw identifiers that may alias keywords
* Review comments
* Disallow hashless raw identifiers in interpolations
* Run clang-format
* Clarify the operator relationship of ordinary and fixed-point numbers
* Attempt to clarify description of fixed-point numbers
* Note that RGBASM does not check fixed-point precisions
* Simplify sine table example a bit
* Remove misleading equations describing `DIV`, `MUL`, and `FMOD`
* Various minor style and formatting fixups
- FIX: `Label & const` was not actually doing the `& const` masking
(fixes#1446)
- ADD: `LOW(Label)` can be constant if `Label` is aligned to 8 or more bits
(resolves#1444)
- ADD: `!expr` can be constant 0 if `expr` has any non-zero bits
(resolves#1447)
- `LOW()` and `HIGH()` have their own RPN operator values
(resolves#1445)
The change to RPN values means that the object file version was incremented.
This also refactors unary operators and functions, combining their
evaluation similarly to binary ones.
