13 years agoi965: Set up clip distance VUE slots appropriately for gl_ClipDistance.

i965: Set up clip distance VUE slots appropriately for gl_ClipDistance.

When gl_ClipDistance is in use, the contents of the gl_ClipDistance
array just need to be copied directly into the clip distance VUE
slots, so we re-use the code that copies all other generic VUE slots
(this has been extracted to its own method).  When gl_ClipDistance is
not in use, the vertex shader needs to calculate the clip distances
based on user-specified clipping planes.

This patch also removes the i965-specific enum values
BRW_VERT_RESULT_CLIP[01], since we now have generic Mesa enums that
serve the same purpose (VERT_RESULT_CLIP_DIST[01]).

user-defined clipping planes.  Since the driver needs to behave
differently in these two cases, we need a flag to record whether the
shader has written to gl_ClipDistance.

The new flag is called UsesClipDistance.  We initially store it in
gl_shader_program (since that is the data structure that is available

glsl: Implement a lowering pass for gl_ClipDistance.

In i965 GEN6+ (and I suspect most other hardware), gl_ClipDistance
needs to be laid out as a pair of vec4's (the first containing clip
distances 0-3, and the second containing clip distances 4-7).
However, it is declared in GLSL as an array of 8 floats.

This lowering pass acts at the GLSL level, modifying the declaration
of gl_ClipDistance so that it is an array of vec4's rather than an
array of floats, and renaming it to gl_ClipDistanceMESA.  In addition,
it modifies all accesses to the array so that they access the
appropiate component of one of the vec4's.

Since some hardware may not internally represent gl_ClipDistance as a
pair of vec4's, this lowering pass is optional.  To enable it, set the
LowerClipDistance flag in gl_shader_compiler_options to true.
