- Add new keyword int64_t/uint64_t/i64vec/u64vec.
- Support 64-bit integer literals (dec/hex/oct).
- Support built-in operators for 64-bit integer type.
- Add implicit and explicit type conversion for 64-bit integer type.
- Add new built-in functions defined in this extension.
When an include directive is recognized by the preprocessor, it
executes a callback on the filepath argument to obtain the file
contents. That way the compilation client can deal with the file
system, include paths, etc.
Currently only accepts quoted filepaths -- no angle brackets yet.
This simplification is a prelude to eliminating what I appear unnecessary
symbol inserts into tables when tokenizing in the preprecessor, which
show up as taking notable time. (Performance issue.) It also simply makes
the preprocessor easier to understand, which it is badly in need of.
- macro expansion of hexidecimal numbers
- give errors instead of warnings/silence on extra tokens after #endif, #else, etc.
- give errors on reserved macro name use, reuse of argument, and redefinition with different whitespace presence
- detect and give error for all cases of #elif and #else after #else
