Created attachment 40658 [details] new test case for piglit shader_runner below array is declared with implicit size, but after initialization (so it should be explicitly sized) it's still (wrongly) considered as unsized. uniform float a[] = float[](0,1,2,3,4); The attached case fails with below error: Failed to compile FS: 0:5(15): error: length called on unsized array. PIGLIT: {'result': 'fail' } It will pass if the array is local variable instead of uniform variable. Tested on Piketon (i965) with mesa master.
Test case (attachment id=40658) committed to piglit. commit 4a80100f8c735bc055bde1f18e4052c311f20eb3 Author: Gordon Jin <gordon.jin@intel.com> Date: Fri Dec 3 22:58:07 2010 -0800 glsl-array-uniform-length: Add test case from FDO bug 31985.
The piglit test array-compare-04.vert (bug #32035) also hits this issue. Fixed by: commit 7bdaa2c5ad7ef02c1c97367839962ec03361c528 Author: Ian Romanick <ian.d.romanick@intel.com> Date: Tue Dec 7 16:27:22 2010 -0800 glsl: Inherrit type of declared variable from initializer Types of declared variables and their initializer must match excatly except for unsized arrays. Previously the type inherritance for unsized arrays happened implicitly in the emitted assignment. However, this assignment is never emitted for uniforms. Now that type is explicitly copied unconditionally. Fixes piglit test array-compare-04.vert (bugzilla #32035) and glsl-array-uniform-length (bugzilla #31985). NOTE: This is a candidate for the 7.9 branch.

oh, forgot this is being tracked for 7.9.
commit 7b6b66d617b1f14f79fb7af2dad268a68e35b9e3 Author: Ian Romanick <ian.d.romanick@intel.com> Date: Fri Dec 17 13:50:40 2010 -0800 glsl: Inherrit type of declared variable from initializer after processing a do_assignment may apply implicit conversions to coerce the base type of initializer to the base type of the variable being declared. Fixes piglit test glsl-implicit-conversion-02 (bugzilla #32287). This probably also fixes bugzilla #32273. NOTE: This is a candidate for the 7.9 branch and the 7.10 branch.

That was the wrong commit.
