<code class="function">glUseProgramStages</code> binds executables from a program object
associated with a specified set of shader stages to the program pipeline object given
by <em class="parameter"><code>pipeline</code></em>.
<em class="parameter"><code>pipeline</code></em> specifies the program pipeline object to which to bind
the executables. <em class="parameter"><code>stages</code></em> contains a logical combination of bits
indicating the shader stages to use within <em class="parameter"><code>program</code></em> with the program
pipeline object <em class="parameter"><code>pipeline</code></em>. <em class="parameter"><code>stages</code></em> must be
a logical combination of <code class="constant">GL_VERTEX_SHADER_BIT</code>,
<code class="constant">GL_TESS_CONTROL_SHADER_BIT</code>, <code class="constant">GL_TESS_EVALUATION_SHADER_BIT</code>,
<code class="constant">GL_GEOMETRY_SHADER_BIT</code>, <code class="constant">GL_FRAGMENT_SHADER_BIT</code> and <code class="constant">GL_COMPUTE_SHADER_BIT</code>.
Additionally, the special value <code class="constant">GL_ALL_SHADER_BITS</code> may be specified to
indicate that all executables contained in <em class="parameter"><code>program</code></em> should be
installed in <em class="parameter"><code>pipeline</code></em>.
</p><p>
If <em class="parameter"><code>program</code></em> refers to a program object with a valid shader attached for
an indicated shader stage, <code class="function">glUseProgramStages</code> installs the executable
code for that stage in the indicated program pipeline object <em class="parameter"><code>pipeline</code></em>.
If <em class="parameter"><code>program</code></em> is zero, or refers to a program object with no valid shader
executable for a given stage, it is as if the pipeline object has no programmable stage configured
for the indicated shader stages. If <em class="parameter"><code>stages</code></em> contains bits other than those
listed above, and is not equal to <code class="constant">GL_ALL_SHADER_BITS</code>, an error is generated.
</p></div><div class="refsect1"><a id="notes"></a><h2>Notes</h2><p>
The <code class="constant">GL_COMPUTE_SHADER_BIT</code> bit is available only if the GL version is 4.3 or greater.
</p></div><div class="refsect1"><a id="errors"></a><h2>Errors</h2><p>
<code class="constant">GL_INVALID_VALUE</code> is generated if <em class="parameter"><code>shaders</code></em> contains
set bits that are not recognized, and is not the reserved value <code class="constant">GL_ALL_SHADER_BITS</code>.
</p><p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>program</code></em> refers
to a program object that was not linked with its <code class="constant">GL_PROGRAM_SEPARABLE</code> status set.
</p><p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>program</code></em> refers
to a program object that has not been successfully linked.
</p><p>
<code class="constant">GL_INVALID_OPERATION</code> is generated if <em class="parameter"><code>pipeline</code></em> is not
a name previously returned from a call to <a class="citerefentry" href="glGenProgramPipelines.xml"><span class="citerefentry"><span class="refentrytitle">glGenProgramPipelines</span></span></a>
