Currently, state-changes in mesa display lists are more or less
a verbatim recording of the GL calls made during compilation.
This change introduces a minor optimization to recognize and eliminate
cases where the application emits redundant state changes, eg:
glShadeModel( GL_FLAT );
glBegin( prim )
...
glEnd()
glShadeModel( GL_FLAT );
glBegin( prim )
...
glEnd()
The big win is when we can eliminate all the statechanges between two
primitive blocks and combine them into a single VBO node.
This commit implements state-change elimination for Material and ShadeModel
only. This is enough to make a start on debugging, etc.

Be clearer that this is the number of generic vertex program/shader
attributes, not counting the legacy attributes (pos, normal, color, etc).

Only enabled for software drivers at this point.
Note that the gl_buffer_object::Access enum field has been replaced by
a gl_buffer_object::AccessFlags bitfield. The new field is a mask of
the GL_MAP_x_BIT flags which is a superset of the old GL_READ_ONLY,
GL_WRITE_ONLY and GL_READ_WRITE modes. When we query GL_BUFFER_ACCESS_ARB
we translate the bitfield into the conventional enum values.

Use MAX_VERTEX_GENERIC_ATTRIBS instead. No need for two #defines for
the same quantity.

This fixes an issue when compiling glCallList() into another display list
when the mode is GL_COMPILE_AND_EXECUTE.
Before, the call to glCallList() called _mesa_save_CallList() which called
neutral_CallList() which then called _mesa_save_CallList() again. In the
end, the parent display list contained two calls to the child display list
instead of one.
Let's be on the lookout for regressions caused by this change for a while
before we cherry-pick this elsewhere.

add new entrypoints, new texture format, etc
translate in texenvprogram.c for drivers using the mesa-generated tex env

results not handled correctly)

This trims down and cleans up imports.h and glheader.h quite a bit.

Remove some unneeded fields. Rename some function parameters.

|
Rename some structs and fields to be more consistant with the rest of mesa.

Use floor() to convert to int (per Mark Kildard and the SI).
Also, change translate_id() to return a signed integer since we may be
offsetting from GL_LIST_BASE.

More such shader functions are needed...

As glPixelStore(GL_UNPACK) affect the bits into a stipple pattern,
hence 128 bytes used to store the pattern in a display list aren't
enough sometimes.

Remove display list opcodes for INDEX and EDGEFLAG, handle them
through the regular ATTRIB mechanism now that Mesa understands them
to just be regular attribs.

glDeleteTextures and glDeleteTexturesEXT were erroneously listed as
aliases of each other. For anything /except/ GLX protocol they are
aliases. This set of changes allows functions that are functionally
identical but have different GLX protocol to be listed as aliases.
When building with GLX_INDIRECT_RENDERING set, different static
functions are used. These functions determine whether the current
context is direct rendering or not. If the context is direct
rendering, the aliased function (e.g., glDeleteTextures in the case of
glDeleteTexturesEXT) is called. If the context is not direct
rendering, the correct GLX protocol is sent.
For a deeper explanation of what is changed, please see:

The functions for GL_EXT_paletted_texture that do not share GLX
protocol with GL_ARB_imaging are supposed to alias the similar
functions from GL_SGI_color_table. They didn't. This patch corrects
this problem and enables GLX protocol for both extensions.
Since this removes 3 entries from the dispatch table, this change
creates a lot of changes in the generated files.

either GL_ARB_vertex_program or GL_ARB_fragment_program should enable this

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.
|
|
Update a lot of loops, conditionals to use the _TNL_FIRST/LAST_* values
instead of specific vertex attributes.
Remove the EdgeFlagv function from the GLvertexformat struct.

- use macros to access and modify render inputs bit-field;
- un-alias generic vertex attributes for ARB vertex calls;
- use MAX_VERTEX_PROGRAM_ATTRIBS (NV code) or MAX_VERTEX_ATTRIBS
(ARB code) in place of VERT_ATTRIB_MAX;
- define VERT_ATTRIB_GENERIC0..15 for un-aliased vertex
attributes for ARB_vertex_shader;
- fix generic attribute index range check in arbprogparse.c;
- interface GLSL varyings between vertex and fragment shader;
- use 64-bit optimised bitset (bitset.h) for render inputs;

glVertexAttrib() w/ bad index should generate GL_INVALID_VALUE, not
GL_INVALID_ENUM.
Misc clean-ups.
