2006-04-05Check/use texture border color when sampling depth textures. (bug 6498)Brian Paul
Silence some warnings.
2006-04-04Fix texcoord interpolation for fragment shaders.Michal Krol
2006-03-29put braces around RENDER_SPAN macro when called, not when defined. Fixes ↵Brian Paul
-pedantic warnings in x11 driver
2006-03-29fix a GLuint vs GLushort test, new assertionsBrian Paul

2006-03-25remove carriage returnsBrian Paul
2006-03-22Need to check for new state and do readpixels/drawpixels clipping afterBrian Paul
we call RENDER_START since that may involve validating the drawable and updating its dimensions.
2006-03-21GLSL fixes:Michal Krol
- 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;

2006-03-03Fix bogus span mask in s_atifragshader.c leading to trouble when the pixel ↵Roland Scheidegger
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).

2006-02-27More GLSL code:Michal Krol
- 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;

possible values: SATURATE_OFF, SATURATE_ZERO_ONE and SATURATE_PLUS_MINUS_ONE.
2005-11-19No longer derive 'ati_fragment_shader' from 'program' class. Only theBrian Paul
program->Id and program->RefCount fields were used and ATI fragment shaders didn't have too much in common with ARB/NV vertex/fragment programs anyway.
