* mesa: Add a flag to indicate whether a program uses gl_ClipDistance.Paul Berry2011-09-233-1/+12
| | | | | | | | | | | | | | | | | | GLSL 1.30 requires us to use gl_ClipDistance for clipping if the vertex shader contains a static write to it, and otherwise use 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 when we check to see whethe gl_ClipDistance was written to), and we later copy it to a flag with the same name in gl_vertex_program, since that is a more convenient place for the driver to access it (in i965, at least).

* glsl: Implement a lowering pass for gl_ClipDistance.Paul Berry2011-09-236-0/+351
| | | | | | | | | | | | | | | | | | | 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. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl hierarchical visitor: Do not overwrite base_ir for parameter lists.Paul Berry2011-09-232-7/+17
| | | | | | | | | | | | | | This patch fixes a bug in ir_hirearchical_visitor: when traversing an exec_list representing the formal or actual parameters of a function, it modified base_ir to point to each parameter in turn, rather than leaving it as a pointer to the enclosing statement. This was a problem, since base_ir is used by visitor classes to locate the statement containing the node being visited (usually so that additional statements can be inserted before or after it). Without this fix, visitors might attempt to insert statements into parameter lists. Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | It is sometimes useful to examine the first frame or and early frame of a quickly executing and non-repeating application, this chain introduces a new environment variable that is checked when creating contexts.

| | | | | | | | | | | There were notes about the possibility of slowdowns due to zcopy from a PBO due to thrashing around of the region. Slowdowns are even more likely now that textures are generally tiled, which a zcopy wouldn't get. Additionally, there were no checks on the buffer size to ensure that the hardware-required rounding was present, which could result in GPU hangs on large zcopy PBOs.
