GLSL optimizer Change Log
|
|
=========================
|
|
|
|
2014 03
|
|
-------
|
|
|
|
Fixes:
|
|
|
|
* Fixed missing precision qualifier in some ES shaders (mostly due to expansion of ternary ?: check).
|
|
|
|
2014 02
|
|
-------
|
|
|
|
Fixes:
|
|
|
|
* Fixed vectorize pass introduced last month going wrong with dot products.
|
|
|
|
2014 01
|
|
-------
|
|
|
|
Goodies:
|
|
|
|
* Better optimization: vectorize assignments to individual vector channels.
|
|
* More OpenGL ES 2.0 conformant printing of complex for-loops (loop inductions printed
|
|
as += or ++; loop initializers inside loop body).
|
|
|
|
Fixes:
|
|
|
|
* Fixed array assignments sometimes appearing in pre-GLSL1.20 versions, especially with
|
|
complex loops that couldn't be unrolled.
|
|
* Fixed output of textureOffset and texelFetch.
|
|
* Fixed error messages on MRT outputs on GL & GLES3 (now supports 4 MRTs).
|
|
|
|
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
