This page describes the features and status of Mesa's support for the

OpenGL Shading Language</a>.

<li><b>log</b> - log all GLSL shaders to files.
The filenames will be "shader_X.vert" or "shader_X.frag" where X
the shader ID.
+<li><b>cache_info</b> - print debug information about shader cache
<li><b>nopt</b> - disable compiler optimizations
<li><b>opt</b> - force compiler optimizations
<li><b>uniform</b> - print message to stdout when glUniform is called
</ul>

Options include
<li><b>--dump-ast</b> - dump GPU code
<li><b>--dump-hir</b> - dump high-level IR code
<li><b>--dump-lir</b> - dump low-level IR code
-<li><b>--link</b> - ???
+<li><b>--dump-builder</b> - dump GLSL IR code
+<li><b>--link</b> - link shaders
+<li><b>--just-log</b> - display only shader / linker info if exist,
+without any header or separator
+<li><b>--version</b> - [Mandatory] define the GLSL version to use
</ul>
<p>
The source code for Mesa's shading language compiler is in the
-<code>src/glsl/</code> directory.
