* glsl: Allow elimination of uniform block membersIan Romanick2013-01-251-6/+1
| | | | | | | | | | | | | | | | | | | glGetActiveUniform is not supposed to report block members that are not active even if they are included in the layout of the block. The block layout is determined from the GLSL_TYPE_INTERFACE that defines the block, so eliminating the ir_variables that correspond to the individual fields is safe. Fixes gles3conform test uniform_buffer_object_getuniformindices_for_for_nonexistent_or_not_active_uniform_names. This also fixes the assertion failures (added in the previous commit) in gles3conform uniform_buffer_object_index_of_not_active_block, uniform_buffer_object_inherit_and_override_layouts, and uniform_buffer_object_repeat_global_scope_layouts.

| | | | | | | | | | | | | | | | | | | | | | | In GLSL ES 3.00 (and GLSL 1.50), uniform blocks can have an associated "instance name", which essentially namespaces the variables inside. This patch adds basic parsing for this new feature, but doesn't yet hook it up to actually do anything yet. It does not support for arrays of interface blocks; a later commit will take care of that. This change temporarily regresses the piglit test interface-name-access-without-interface-name.vert. This shader failed to compile before (the expected result), but it failed to compile for the wrong reason. This is not a real regression. v2: Add some comments to ast_uniform_block::instance_name.
