This is important for some apps under Wine to run. Wine sometimes declares a uniform array of 256 vec4's and some Wine-specific constants on top of that, so in total there is more uniforms than r300 can handle. This was the main motivation for implementing the elimination of unused constants. We should allow drivers to implement fail & recovery paths where it makes sense, so giving up too early especially when comes to uniforms is not so good idea, though I agree there should be some hard limit for all drivers. This patch fixes: - glsl-fs-uniform-array-5 - glsl-vs-large-uniform-array on drivers which can eliminate unused uniforms. 2011-03-12T23:11:01Z Eric Anholt eric@anholt.net 2011-03-12T23:00:55Z urn:sha1:098f9c5325de16bfb5bf8b0e93e0ec1871db4a76 This reverts commit 7cb87dffce2c7a37f960f3a865cf92fd193dd8c5. There were regressions (Bug #35244) and more review has been requested. 2011-03-11T20:55:14Z Eric Anholt eric@anholt.net 2010-11-01T20:16:21Z urn:sha1:7cb87dffce2c7a37f960f3a865cf92fd193dd8c5 This is a step towards providing a direct route for drivers accepting GLSL IR for codegen. Perhaps more importantly, it runs the fixed function fragment program through the GLSL IR optimization. Having seen how easy it is to make ugly fixed function texenv code that can do unnecessary work, this may improve real applicatinos. 2011-03-11T20:55:13Z Eric Anholt eric@anholt.net 2010-11-05T14:25:18Z urn:sha1:e1cb12bfff7f65c3599c9b68b9269f73942b1602 This is used in the upcoming fixed function shader_program generation, and shader_program and ARB programs are together in this code until both fragment and vertex ff get converted. 2011-03-11T17:04:17Z Brian Paul brianp@vmware.com 2011-03-11T17:03:40Z urn:sha1:d7db14ab7d66520b6030c0aa48c94507179a8d4e Since we're compiling/linking GLSL shaders we should check against the shader uniform limits, not the legacy vertex/fragment program parameter limits which are usually lower. 2011-03-11T16:25:22Z Brian Paul brianp@vmware.com 2011-03-11T16:25:22Z urn:sha1:e0e94026a0648d6b33d6b7cf2b9b01429cf945e4 The gl_program_constants struct is for limits that are applicable to any/all shader stages. Move the geometry shader-only fields into the gl_constants struct. Remove redundant MaxGeometryUniformComponents field too. 2011-03-11T16:25:22Z Brian Paul brianp@vmware.com 2011-03-11T16:25:22Z urn:sha1:8cc84b3e454cf03c71282322e988f03bc4a1baa3 Without these checks we could create shaders with more samplers, constants than the driver could handle. Fail linking rather than dying later.
