- * usage:
- * syn2c slang_shader.syn > slang_shader_syn.h
- *
- * when modifying or extending this file, several things must be taken into
- * consideration:
- *
- * - when adding new operators that were marked as reserved in the
- * initial specification, one must only uncomment particular lines of
- * code that refer to operators being added;
- *
- * - when adding new shader targets, one must reserve a new value for
- * shader_type register and use it in .if constructs for symbols that
- * are exclusive for that shader;
- *
- * - some symbols mimic output of other symbols - the best example is
- * the "for" construct: expression "for (foo(); ; bar())" is seen as
- * "for (foo(); true; bar())" by the output processor - hence, special
- * care must be taken when rearranging output of essential symbols;
- *
- * - order of single-quoted tokens does matter in alternatives - so do not
- * parse "<" operator before "<<" and "<<" before "<<=";
- *
- * - all double-quoted tokens are internally preprocessed to eliminate
- * problems with parsing strings that are prefixes of other strings,
- * like "sampler1D" and "sampler1DShadow";
