The specification says that commas within a parenthesized group,
(that's not a function-like macro invocation), are passed through
literally and not considered argument separators in any outer macro
invocation.
Add support and a test for this case. This support makes a third
occurrence of the same "FUNC_MACRO (" shift/reduce conflict appear, so
expect that.
This change does introduce a fairly large copy/paste block in the
grammar which is unfortunate. Perhaps if I were more clever I'd find a
way to share the common pieces between argument and argument_or_comma.
glcpp -- GLSL "C" preprocessor This is a simple preprocessor designed to provide the preprocessing needs of the GLSL language. The requirements for this preprocessor are specified in the GLSL 1.30 specification availble from: http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.30.08.pdf This specification is not precise on some semantics, (for example, #define and #if), defining these merely "as is standard for C++ preprocessors". To fill in these details, I've been using the C99 standard (for which I had a convenient copy) as available from: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf
