GLSL optimizer Change Log

2014 01

Goodies:

  • More OpenGL ES 2.0 conformant printing of complex for-loops (loop inductions printed as += or ++; loop initializers inside loop body).

2013 12

Goodies:

  • Optimized performance; was spending half of the time in stupid string code.
  • Added glslopt_shader_get_stats to get very approximate shader complexity stats.
  • Nicer printing of complicated for-loops.

Fixes:

  • Fixed printing of struct initializers.

2013 11

Goodies:

  • Better optimizations: CSE; A+(-B) => A-B; !A || !B => !(A && B).
  • Merged with upstream Mesa.

Fixes:

  • Fixed location qualifiers, ES3.0 version printing, samplerCubeShadow sampling operations.

2013 10

Goodies:

  • Initial OpenGL ES 3.0 support
  • API to query shader input names; glslopt_shader_get_input_count and glslopt_shader_get_input_name

Changes:

  • Xcode project files updated to Xcode 5

Fixes:

  • VS2013 fixes
