This also passes for me with chromium and mesa master on ivb. Browser details required. Update chrome to version 27.0.1453.73.Following cases still fail: conformance/glsl/functions/glsl-function-acos.html conformance/glsl/functions/glsl-function-asin.html conformance/glsl/functions/glsl-function-atan-xy.html conformance/glsl/functions/glsl-function-atan.html conformance/glsl/functions/glsl-function-cos.html conformance/glsl/functions/glsl-function-sin.html conformance/glsl/functions/glsl-function-smoothstep-float.html conformance/glsl/literals/float_literal.vert.html conformance/glsl/misc/shader-varying-packing-restrictions.html conformance/glsl/misc/shader-with-global-variable-precision-mismatch.html conformance/glsl/misc/shaders-with-varyings.html conformance/glsl/samplers/glsl-function-texture2dlod.html conformance/glsl/variables/glsl-built-ins.html conformance/uniforms/gl-uniform-arrays.html Are you still able to reproduce this? Test on IVB with latest mesa master branch. conformance/uniforms/gl-uniform-arrays.html still fails. Okay. I just tried with Mesa master (e06b077) and Firefox 26, and this test passes. As was requested over a year ago, we need more details about your browser and its configuration. (In reply to Ian Romanick from comment #5) > Okay.

I test conformance/uniforms/gl-uniform-arrays.html on latest mesa master branch and chrome 39. I will test full webglc case. Test on HSW with the latest Mesa master branch and 10.4(5fe79b0b127). Chrome version is 39. Following cases fail on both master and 10.4 branch: conformance/extensions/webgl-debug-shaders.html conformance/glsl/misc/shader-varying-packing-restrictions.html conformance/glsl/literals/float_literal.vert.html conformance/glsl/misc/shaders-with-varyings.html conformance/misc/webgl-specific.html conformance/ogles/mustpass.run.txt conformance/typedarrays/array-unit-tests.html (In reply to lu hua from comment #7) > Test on HSW with the latest Mesa master branch and 10.4(5fe79b0b127). Chrome > version is 39. I tested it with ubuntu 15.10 mesa (11.0.2) and current master (git-edf774b) on both Chromium (Chromium 48.0.2564.82 Ubuntu 15.10) and Chrome (Google Chrome 48.0.2564.109). Didn't try with Firefox, as comment #5 mentions that was working properly. > Following cases fail on both master and 10.4 branch: > conformance/extensions/webgl-debug-shaders.html > conformance/glsl/misc/shader-varying-packing-restrictions.html > conformance/glsl/literals/float_literal.vert.html > conformance/glsl/misc/shaders-with-varyings.html > conformance/misc/webgl-specific.html > conformance/ogles/mustpass.run.txt > conformance/typedarrays/array-unit-tests.html Now the tests failing are: conformance/glsl/literals/float_literal.vert.html: 1 tests failed conformance/limits/gl-min-textures.html: 2 tests failed float-literal was present on comment #7 list, gl-min-textures not. In both cases, they are failing because the shaders are wrong on version #130, as google-chrome expose the webgl shaders with that version. But WebGL 1.0 specifies OpenGL ES 1.0 [1], and those shaders are correct with #version 100. Going to the details: * float-literal is failing because the vertex shader doesn't write on gl_Position. This is allowed on OpenGL ES 1.0. See the spec, section 10.13 [2] There is a piglit test handling this scenario, that properly passes: ./bin/shader_runner_gles2 ./tests/spec/glsl-es-1.00/linker/glsl-no-glposition.shader_test -auto * gl-min-textures is failing because it is accessing a sampler array with a constant-index-expression. This is allowed on OpengGL ES 1.0. See the spec, Appendix A [2] There is a piglit test handling this scenario, that properly passes: ./bin/glslparsertest_gles2 tests/spec/glsl-es-1.00/compiler/structure-and-array-operations/sampler-array-index.frag pass 1.00 FWIW, gl-min-textures passes properly using epiphany browser. With all this in mind, I think that it would be safe to close the bug as NOTOURBUG, as the problem is caused by the glsl version specified by chrome when exporting the shaders. But I would let people give his opinion, just in case.
