* mesa: Don't leak shared state when context initialization failsIan Romanick2013-04-121-0/+1
| | | | | | | | | | | | | | | | | Back up at line 1017 (not shown in patch), we add a reference to the shared state. Several places after that may divert to the error handler, but, as far as I can tell, nothing ever unreferences the shared state. Fixes issue identified by Klocwork analysis: Resource acquired to 'shared->TexMutex' at line 1012 may be lost here. Also there is one similar error on line 1087.

* i965/vs: Generalize computation of array strides in preparation for GS.Paul Berry2013-04-112-4/+16
| | | | | | | | | | | | | | | | | | | Geometry shader inputs are arrays, but they use an unusual array layout: instead of all array elements for a given geometry shader input being stored consecutively, all geometry shader inputs are interleaved into one giant array. As a result, the array stride we use to access geometry shader inputs must be equal to the size of the input VUE, rather than the size of the array element. This patch introduces a new virtual function, vec4_visitor::compute_array_stride(), which will allow geometry shader compilation to specialize the computation of array stride to account for the unusual layout of geometry shader input arrays. It also renames the local variable that the ir_dereference_array visitor uses to store the stride, to avoid confusion.

* i965/vs: Generalize vertex emission code in preparation for GS.Paul Berry2013-04-113-19/+59
| | | | | | | | | | | | | | | | | | | | This patch introduces a new function, vec4_visitor::emit_vertex(), which contains the code for emitting vertices that will need to be common between the vertex and geometry shaders. Geometry shaders will need to use a different message header, and a different opcode, for their URB writes, so we introduce virtual functions emit_urb_write_header() and emit_urb_write_opcode() to take care of the GS-specific behaviours. Also, since vertex emission happens at the end of the VS, but in the middle of the GS, we need to be sure to only call emit_shader_time_end() during VS vertex emission. We accomplish this by moving the call to emit_shader_time_end() into the VS implementation of emit_urb_write_opcode().

Having brw_vs_compile point to brw_vs_prog_data makes it difficult to do this cleanly. Fortunately most of the functions that use brw_vs_compile (those in the vec4_visitor class) already have access to brw_vs_prog_data through a separate pointer (vec4_visitor::prog_data). So all we have to do is use that pointer consistently, and plumb prog_data through the few remaining functions that need access to it.
