This is similar to what r300 does inside the driver, but I've added it as
a generic option since it seems most hardware will want it.
Fixes piglit nv-init-zero-reg.vpfp and nv-init-zero-addr.vpfp.

This helps let drivers treat NV_vp like ARB_vp.

Use _NEW_PROGRAM_CONSTANTS when changing constant/uniform buffer values.
Binding a new program/shader sets both _NEW_PROGRAM and _NEW_PROGRAM_CONSTANTS.
|
|
This state flag will be used to indicate that vertex/fragment program
constants have changed. _NEW_PROGRAM will be used to indicate changes
to the vertex/fragment shader itself, or misc related state.
_NEW_PROGRAM_CONSTANTS is also set whenever a program parameter that's
tracking GL state has changed. For example, if the projection matrix is
in the parameter list, calling glFrustum() will cause _NEW_PROGRAM_CONSTANTS
to be set. This will let to remove the need for dynamic state atoms in
some drivers.
For now, we still set _NEW_PROGRAM in all the places we used to. We'll no
longer set _NEW_PROGRAM in glUniform() after drivers/etc have been updated.

This is another step toward removing a whole bunch of -I flags from
the cc commands. Still need to address driver code...
|
|
these should be the same functions (as per spec).

a lot of casting elsewhere.
Use _mesa_lookup_texture() in tdfx driver, use _mesa_lookup_bufferobj() in r300
driver.

"gl_" to match other structs.

and demos are also added.
Adding basic support to drivers should be as easy as just enabling the
extension, though thorough test would also be required.

Instructions, InputsRead, OutputsWritten, and Parameters.
Also, added debug functions: _mesa_print_instruction(),
_mesa_print_program_parameters() and revamp _mesa_print_program().

Based on patch by Ian (#4967) but also unify instruction opcodes.

use 64-bit pointers and 32-bit longs. So, operations like casting pointers
to unsigned long and back to pointer won't work. glheader.h now
includes files to define uintptr_t, which should instead be used for
this sort of operation. It is an integer type that is the same size
as a pointer.

Fixes problems found with Cg demos.
|
|
Some need to be set per-vertex, other per-primitive. Cleared that up.
Only need to init temp/result registers if executing an NV vertex program.
