* Treat image units and coordinate units differently.Ian Romanick2009-01-141-3/+28
| | | | | | | | | | | | Previously MaxTextureUnits was used to validate both texture image units and texture coordinate units in fragment programs. Instead, use MaxTextureCoordUnits for texture coordinate units and MaxTextureImageUnits for texture image units. Fixes bugzilla #19468.

* glsl: force creation of new scope for for-loop bodyBrian Paul2009-01-101-0/+18
| | | | | | | | | | | Fixes regression in progs/demos/convolution.c due to loop unrolling. This also allows the following to be compiled correctly: for (int i = 0; i < n; i++) { int i; ... } This fix is a bit of a hack, however. The better fix would be to change the slang_shader.syn grammar. Will revisit that...

* glsl: make minimum struct size = 2, not 1Brian Paul2009-01-091-1/+8
| | | | | | | 1-component structs such as "struct foo { float x; }" could get placed at any position within a register. This caused some trouble computing the field offset which assumed all struct objects were placed at R.x. It would be unusual to hit this case in normal shaders.

* glsl: fix broken +=, -=, *=, /= operatorsBrian Paul2009-01-082-737/+786
| | | | | | | These functions need to return the final computed value. Now expressions such as a = (b += c) work properly. Also, no need to use __asm intrinsics in these functions. The resulting code is the same when using ordinary arithmetic operators and is more legible.

* glsl: implement loop unrolling for simple 'for' loopsBrian Paul2009-01-061-24/+205
| | | | | | | | | | | | | | | | | Loops such as this will be unrolled: for (i = 0; i < 4; ++i) { body; } where 'body' isn't too large. This also helps to fix the issue reported in bug #19190. The problem there is indexing vector types with a variable index. For example: vec4 v; v[2] = 1.0; // equivalent to v.z = 1.0 v[i] = 2.0; // variable index into vector!! Since the for-i loop can be unrolled, we can avoid the problems associated with variable indexing into a vector (at least in this case).

* mesa: fix another "out of samplers" problemBrian Paul2009-01-023-18/+50
| | | | | | Now only the samplers that are actually used by texture() functions are saved in the uniform variable list. Before, we could run out of samplers if too many were declared while only some of them were actually used.

* mesa: increase max texture image units and GLSL samplers to 16Brian Paul2008-12-312-6/+7
| | | | | | | | | | | | | | | | The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.
* mesa: fix bug in evaluation of structure fieldsBrian Paul2008-12-301-3/+1
| | | | Fixes incorrect size information. See bug 19273.
* mesa: allow variable indexing into the predefined uniform variable arraysBrian Paul2008-12-305-91/+376
| | | | | | | | | | | | | | | | | | | This allows code such as "vec4 a = gl_LightSource[i].ambient;" to work. When a built-in uniform array is indexed with a variable index we need to "unroll" the whole array into the parameter list (aka constant buffer) because we don't know which elements may be accessed at compile-time. In the case of the gl_LightSource array of size [8], we emit 64 state references into the parameter array (8 elements times 8 vec4s per gl_LightSourceParameters struct). Previously, we only allowed constant-indexed references to uniform arrays (such as gl_LightSource[2].position) which resulted in a single state reference being added to the parameter array, not 64. We still optimize this case. Users should be aware that using "gl_LightSource[i].ambient" in their shaders is a bit expensive since state validation will involve updating all 64 light source entries in the parameter list.
