|
|
* GLSL linker implementation
|
|
*
|
|
* Given a set of shaders that are to be linked to generate a final program,
|
|
* there are three distinct stages.
|
|
*
|
|
* In the first stage shaders are partitioned into groups based on the shader
|
|
* type. All shaders of a particular type (e.g., vertex shaders) are linked
|
|
* together.
|
|
*
|
|
* - Undefined references in each shader are resolve to definitions in
|
|
* another shader.
|
|
* - Types and qualifiers of uniforms, outputs, and global variables defined
|
|
* in multiple shaders with the same name are verified to be the same.
|
|
* - Initializers for uniforms and global variables defined
|
|
* in multiple shaders with the same name are verified to be the same.
|
|
*
|
|
* The result, in the terminology of the GLSL spec, is a set of shader
|
|
* executables for each processing unit.
|
|
*
|
|
* After the first stage is complete, a series of semantic checks are performed
|
|
* on each of the shader executables.
|
|
*
|
|
* - Each shader executable must define a \c main function.
|
|
* - Each vertex shader executable must write to \c gl_Position.
|
|
* - Each fragment shader executable must write to either \c gl_FragData or
|
|
* \c gl_FragColor.
|
|
*
|
|
* In the final stage individual shader executables are linked to create a
|
|
* complete exectuable.
|
|
*
|
|
* - Types of uniforms defined in multiple shader stages with the same name
|
|
* are verified to be the same.
|
|
* - Initializers for uniforms defined in multiple shader stages with the
|
|
* same name are verified to be the same.
|
|
* - Types and qualifiers of outputs defined in one stage are verified to
|
|
* be the same as the types and qualifiers of inputs defined with the same
|
|
* name in a later stage.
