* More GLSL code:Michal Krol2006-04-115-117/+237
| | | | | | | | | | | | - 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;

* Replace MESA_FORMAT_DEPTH_COMPONENT_FLOAT32 with 32-bit integer format.Brian Paul2006-04-063-21/+106
| | | | | | | This allows render to depth texture (we don't support floating pt. Z buffers). Rename MESA_FORMAT_DEPTH_COMPONENT16/32 as MESA_FORMAT_Z16/32. Software fallback for glCopyTexImage now uses integer temporary image instead of float, eliminates a lot of float/int conversions.

* GLSL fixes:Michal Krol2006-03-213-741/+742
| | | | | | | | | | | | | | | | | | - generate error on NULL pointers in glShaderSourceARB; - reinstall program object, if current, in glLinkProgramARB; - vertex and fragment shaders are optional in program object; - floor asm was wrongly computed for x86 back-end; - allow for (void) idiom in function prototypes; - all fixed-state uniforms are updated; - local variable initializers are working; - implement texture* and shadow* functions for vertex processor; - generate error if too many arguments in general constructor; - trim unused data in general constructor; - struct r-value field select was badly relocated; Changes: - add derived state gl_fog_attrib::_Scale; - add derived state gl_light::_CosCutoffNeg;

* Fix bogus span mask in s_atifragshader.c leading to trouble when the pixel ↵Roland Scheidegger2006-03-032-6/+8
| | | | was later discarded by z test (this fixes doom3 r200 renderpath with swrast). Fix calling _swrast_alpha_test potentially leading to bogus results when Alpha Test might not be enabled. While here, don't disable deferred_texture (early z) when ATI_fragment_shader is active, as it is not necessary (for the record, this boosts doom3 swrast performance by roughly a factor of 2 (4 seconds per frame now...) with the r200 render path, might be a worthwile optimization for fragment programs which don't write z).

* More GLSL code:Michal Krol2006-02-271-45/+25
| | | | | | | | | | | | | - add x86 code generator; - add full support for uniforms in ARB_shader_objects; - add assembly instruction: global_addr; - reorganize #includes; - built-in uniforms accessed by index, rather than by name; - add some entries to x86sse rtasm; - add configurations to VC6 projects: 'Release x86' and 'Debug x86'; - #define SLANG_X86 active only on VC6 x86 builds; - introduce code export table for a shader; - remove GNU license from the noise library;
