Author: Carl Worth <cwo...@cworth.org> Date: Thu Sep 29 21:44:52 2011 -0700 glcpp: Raise error if defining any macro containing two consecutive underscores The specification reserves any macro name containing two consecutive underscores, (anywhere within the name). Previously, we only raised this error for macro names that started with two underscores. Fix the implementation to check for two underscores anywhere, and also update the corresponding 086-reserved-macro-names test. This also fixes the following two piglit tests: spec/glsl-1.30/preprocessor/reserved/double-underscore-02.frag spec/glsl-1.30/preprocessor/reserved/double-underscore-03.frag Reviewed-by: Kenneth Graunke <kenn...@whitecape.org> Reviewed-by: Eric Anholt <e...@anholt.net> Signed-off-by: Carl Worth <cwo...@cworth.org> --- src/glsl/glcpp/glcpp-parse.y | 4 ++-- src/glsl/glcpp/tests/086-reserved-macro-names.c | 1 + .../tests/086-reserved-macro-names.c.expected | 5 ++++- 3 files changed, 7 insertions(+), 3 deletions(-) diff --git a/src/glsl/glcpp/glcpp-parse.y b/src/glsl/glcpp/glcpp-parse.y index ff9fa7a..17941a9 100644 --- a/src/glsl/glcpp/glcpp-parse.y +++ b/src/glsl/glcpp/glcpp-parse.y @@ -1663,8 +1663,8 @@ _check_for_reserved_macro_name (glcpp_parser_t *parser, YYLTYPE *loc, /* According to the GLSL specification, macro names starting with "__" * or "GL_" are reserved for future use.
