* Wrap every place that accesses a dispatch table with a macro. A new script-Ian Romanick2005-07-181-495/+496
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | generated file, called src/mesa/glapi/dispatch.h, is added. This file contains three macros for each API function. It contains a GET, a SET, and a CALL. Each of the macros take a pointer to the context and a pointer to the dispatch table. In several threads on mesa3d-dev we discussed replacing _glapi_add_entrypoint with a new function called _glapi_add_dispatch. For this discussion, the important difference between the two is that the caller of _glapi_add_dispatch does *not* know what the dispatch offset will be at compile time. Because of this callers need to track the dispatch offset returned by _glapi_add_dispatch. http://marc.theaimsgroup.com/?t=111947074700001&r=1&w=2 The downside is that driver code then has to access the dispatch table two different ways. It accesses it using structure tags (e.g., exec->Begin) for functions with fixed offsets and via a remap table (e.g., exec[ remap->NewExtensionFunction ]) for functions without fixed offsets. Yuck! Using the macros allows both types of functions to be accessed identically. If a driver needs to set a pointer for Begin, it does 'SET_Begin(ctx, exec, my_begin_function)'. If it needs to set a pointer for NewExtensionFunction, it does 'SET_NewExtensionFunction(ctx, exec, my_NewExtensionFunction_function)'. Furthermore, if at some point in the future a static offset is assigned for NewExtensionFunction, only the macros need to change (instead of every single place that accesses a table for that function). This code differs slightly from the originally posted patches in that the CALL, GET, and SET marcos no longer take a context pointer as a parameter. Brian Paul had suggested that the remap table could be stored as a global since it would be set at CreateScreen time and would be constant for all contexts. This change reflects that feedback. http://marc.theaimsgroup.com/?t=112087194700001&r=1&w=2

* Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul2005-05-041-0/+4
| | | | | | | Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
* Add a facility to route all rasterization through a fragment programKeith Whitwell2005-05-041-0/+13
| | | | | | | | | | | which is automatically generated to match the current texture environment state. Introduces a new value ctx->FragmentProgram._Active which is true when either _Enabled is true or there is such a fragment program ready to run. To test out on a driver running the software rasterizer, set MESA_TEX_PROG=t in the environment. It goes without saying that performance is lower for the software rasterizer in this mode.

* Change the dispatch offsets for the VertexAttrib*NV functions so they don'tBrian Paul2004-11-271-3/+3
| | | | | | | alias with the corresponding ARB functions. GL_ARB_vertex_shader (and OpenGL 2.0's) VertexAttrib functions don't alias with conventional vertex attributes, as GL_NV_vertex_program does. So, the ARB and NV version of VertexAttrib need to be distinct.

| | | | | | | Now, compute ctx->Array._MaxElement as the min of enabled array's max element. Test against ctx->Array._MaxElement in glDrawArrays/Elements. Note: testing in glArrayElement not done yet. Only do element checking if ctx->Const.CheckArrayBounds is set.
* Moved some shared vertex/fragment program code into new program.c file.Brian Paul2003-08-311-5/+7
| | | | | | | Implemented new program_parameter_list type and functions for dealing with named program parameters, constants and GL state references. New state_index enum for describing GL state referenced within ARB vertex/ fragment programs. Plus, functions for fetching named GL state.
* Added support for GL_IBM_multimode_draw_arrays.Ian Romanick2003-08-221-0/+6
| | | | | | | | Added non-static entrypoints and the name string for GL_SUN_multi_draw_arrays (identical to GL_EXT_multi_draw_arrays). Made add_newer_entrypoints (in src/mesa/main/context.c) table driven. This reduced the size of context.o by about 3KB.
