The State Of Intel's GLSL2 Compiler
Written by Michael Larabel in Mesa on 10 June 2010 at 03:56 AM EDT. 8 Comments
Intel's Eric Anholt has been working on writing a GLSL2 compiler for their open-source Mesa graphics stack. Mesa's GL Shading Language compiler has been limited to version 1.4 support, but that is changing. In response to the recent ATI R300 GLSL discussion, Eric has provided an update on the Intel efforts.

Eric's branch of Mesa that carries the GLSL2 support for Intel can be found in this repository. Its parser is passing 338 of 363 test cases at present without the preprocessor integrated, which is actually greater than the mainline Mesa parser, but there still are a number of items to tackle. What's left includes actually "gluing" it into Mesa, support for more matrix handling, supporting texture instructions in the Mesa IR code generation, fixing the memory management, integrated the preprocessor, support for loop unrolling, and a few other items.

The status update can be found in this mailing list post.
