Carl Worth	e1acbfca32	glcpp: Avoid accidental token pasting in preprocessed result. ... Consider this test case: #define EMPTY int foo = 1+EMPTY+4; The expression should compile as the sequence of tokens 1, PLUS, UNARY_POSITIVE, 4. But glcpp has been failing for this case since it results in the string "1++4" which a compiler correctly sees as a syntax error, (1, POST_INCREMENT, 4). We fix this by changing any macro with an empty definition to result in a single SPACE token rather than nothing. This then gives "1+ +4" which compiles correctly. This commit does touch up the two existing test cases which already have empty macros, (to add the space to the expected result). It also adds a new test case to exercise the above scenario.	2010-07-20 17:01:12 -07:00
Carl Worth	d80dcaf427	glcpp: Add static keyword to several functions in the parser. ... This quiets warnings about missing declarations otherwise.	2010-07-20 17:01:11 -07:00
Carl Worth	61ebc01dfe	glcpp: Fix use-after-free error from #undef directive. ... By taking advantage of the recently-added hash_table_remove function. With this change, all existing tests are now valgrind-clean.	2010-07-20 17:01:11 -07:00
Ian Romanick	06143ea094	glsl2: Conditionally define preprocessor tokens for optional extensions ... The only optional extension currently supported by the compiler is GL_EXT_texture_array.	2010-07-01 20:40:08 -07:00
Ian Romanick	2d12236117	glsl2: Define preprocessor tokens for extensions ... Currently only GL_ARB_draw_buffers and GL_ARB_texture_rectangle are defined because those extensions are always enabled. This make tex_rect-03.frag pass.	2010-07-01 20:40:08 -07:00
