Kenneth Graunke	47b2af2c62	glsl/s_expression: Read and ignore Scheme-style comments. ... A single-semicolon until the end of the line, i.e. ; this is a comment.	2011-01-12 23:55:34 -08:00
Kenneth Graunke	d798815272	ir_reader: Remove s_list::length() method. ... Most code now relies on the pattern matcher rather than this function, and for the only remaining case, not using this saves an iteration.	2011-01-12 23:55:33 -08:00
Kenneth Graunke	daeb0c646e	ir_reader: Add a pattern matching system and use it everywhere. ... Previously, the IR reader was riddled with code that: 1. Checked for the right number of list elements (via a linked list walk) 2. Retrieved references to each component (via ->next->next pointers) 3. Downcasted as necessary to make sure that each sub-component was the right type (i.e. symbol, int, list). 4. Checking that the tag (i.e. "declare") was correct. This was all very ad-hoc and a bit ugly. Error checking had to be done at both steps 1, 3, and 4. Most code didn't even check the tag, relying on the caller to do so. Not all callers did. The new pattern matching module performs the whole process in a single straightforward function call, resulting in shorter, more readable code. Unfortunately, MSVC does not support C99-style anonymous arrays, so the pattern must be declared outside of the match call.	2011-01-12 23:55:33 -08:00
Brian Paul	bb10e081c8	glsl: new glsl_strtod() wrapper to fix decimal point interpretation ... We always want to use '.' as the decimal point. See http://bugs.freedesktop.org/show_bug.cgi?id=24531 NOTE: this is a candidate for the 7.10 branch.	2010-12-14 12:38:38 -07:00
Kenneth Graunke	d2c23ac82a	glsl: Don't print a useless space at the end of an S-Expression list. ... We really only want to print spaces -between- elements, not after each element. This cleans up error messages from IR reader, making them (mildly) easier to read.	2010-11-03 13:39:41 -07:00
Kenneth Graunke	365ce61997	glsl: Replace sscanf in s_expression reader with strspn and strcspn. ... This seems to give roughly a 20% speedup.	2010-08-18 21:33:18 -07:00
Eric Anholt	2928588267	glsl2: Move the compiler to the subdirectory it will live in in Mesa.	2010-06-24 15:36:00 -07:00
