* glsl: Create a field to store fractional varying locations.Paul Berry2012-12-143-2/+14
| | | | | | | | | | | | | | | Currently, the location of each varying is recorded in ir_variable as a multiple of the size of a vec4. In order to pack varyings, we need to be able to record, e.g. that a vec2 is stored in the second half of a varying slot rather than the first half. This patch introduces a field ir_variable::location_frac, which represents the offset within a vec4 where a varying's value is stored. Varyings that are not subject to packing will always have a location_frac value of zero. Reviewed-by: Eric Anholt <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl/linker: Make separate ir_variable field to mean "unmatched".Paul Berry2012-12-142-4/+23
| | | | | | | | | | | | | | | | | Previously, the linker used a value of -1 in ir_variable::location to denote a generic input or output of the shader that had not yet been matched up to a variable in another pipeline stage. This patch introduces a new ir_variable field, is_unmatched_generic_inout, for that purpose. In future patches, this will allow us to separate the process of matching varyings between shader stages from the processes of assigning locations to those varying. That will in turn pave the way for packing varyings. Reviewed-by: Eric Anholt <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl/linker: Always invalidate shader ins/outs, even in corner cases.Paul Berry2012-12-141-12/+31
| | | | | | | | | | | | | | | | | | Previously, link_invalidate_variable_locations() was only called during assign_attribute_or_color_locations() and assign_varying_locations(). This meant that in the corner case when there was only a vertex shader, and varyings were being captured by transform feedback, link_invalidate_variable_locations() wasn't being called for the varyings. This patch migrates the calls to link_invalidate_variable_locations() to link_shaders(), so that they will be called in all circumstances. In addition, it modifies the call semantics so that link_invalidate_variable_locations() need only be called once per shader stage (rather than once for inputs and once for outputs).

* glsl/lower_clip_distance: Update symbol table.Paul Berry2012-12-143-5/+10
| | | | | | | | | | | | | This patch modifies the clip distance lowering pass so that the new symbol it generates (glClipDistanceMESA) is added to the shader's symbol table. This will allow a later patch to modify the linker so that it finds transform feedback varyings using the symbol table rather than having to iterate through all the declarations in the shader.

* draw/llvmpipe: fix transform feedback position + enable other extensionsDave Airlie2012-12-146-8/+27
| | | | | | | | | | | | | | | | This builds on the previous draw/softpipe patch. So llvmpipe does streamout calls after clip/viewport stages, but we have the pre-clip position stored for later use, so when we are doing transform feedback, and its the position vertex grab the vertex from the stored pre clip position. The perfect fix is too probably add a codegen transform feedback stage in between shader and clip stages, but this is good enough for now.

* draw: add support for later transform feedback extensionsDave Airlie2012-12-143-6/+17
| | | | | | | | | | | | | | | | | This adds support to draw for the new features of transform feedback. a) fix count_from_stream_output, using max_index+1 for now but it looks like it should be valid as its derived from the vertex elements/vbo. b) fix striding and dst offsets in output buffers - was just wrong before. c) fix crash if tfb is suspended (so.num_targets == 0) This also enables the new features on softpipe. It should be possible to enable them on llvmpipe as well after this commit, but would need to schedule piglit runs. Signed-off-by: Dave Airlie <[email protected]>

* mesa: Fix computation of default vertex attrib stride for 2_10_10_10 formats.Paul Berry2012-12-133-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if the client program didn't specify a stride when setting up a vertex attribute, we used _mesa_sizeof_type() to compute the size of the type, and multiplied it by the number of components. This didn't work for the 2_10_10_10 formats, since _mesa_sizeof_type() returns -1 for those types, resulting in all kinds of havoc, since it was causing the hardware to be programmed with a negative stride value. This patch adds a new function _mesa_bytes_per_vertex_attrib(), which is similar to the existing function _mesa_bytes_per_pixel(), but which computes the size of a vertex attribute based on the type and the number of formats. For packed formats (currently only the 2_10_10_10 formats), it verifies that the number of components is correct and returns the size of the packed format. For unpacked formats, it returns the size of the type times the number of components. In addition, this patch adds an assertion so that if we ever forget to update _mesa_bytes_per_vertex_attrib() when adding a new vertex format, we'll see the problem quickly rather than having to debug a subtle conformance test failure. Fixes GLES3 conformance tests vertex_type_2_10_10_10_rev_{conversion,divisor,stride_pointer}.test. Reviewed-by: Brian Paul <[email protected]>
* mesa/uniform_query: Don't write to *params if there is an errorMatt Turner2012-12-131-1/+5
| | | | | | | | | | | | | | | | The GL 3.1 and ES 3.0 specs say of glGetActiveUniformsiv: "If an error occurs, nothing will be written to params." So, make a pass through the indices and check that they're valid before the pass that actually writes to params. Checking pname happens on the first iteration of the second loop. Fixes es3conform's getactiveuniformsiv_for_nonexistent_uniform_indices test. NOTE: This is a candidate for the 9.0 branch.

* i965: Make try_rewrite_rhs_to_dst compare VGRF size to regs written.Kenneth Graunke2012-12-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | try_rewrite_rhs_to_dst is a quick optimization to avoid generating new temporaries (and MOVs from those temporaries to the dest) for every expression tree we visit. By generating better code in simple cases, we reduce the burden on later optimization passes like register coalescing. Previously, we compared inst->regs_written() to lhs->vector_elements to make sure the instruction generating our value wrote the same number of components as our destination register. However, this fails in some cases. One example is texturing (which produces a vec4) into gl_FragData[i]. Technically, gl_FragData[i] is also a vec4. However, the destination VGRF actually has size 4n (where n is the size of the array). split_virtual_grfs() can't split VGRFs that are used by SEND messages which require contiguous destination registers (like texturing), and register allocation needs all VGRFs to have sizes between 1 and 4. Amnesia: The Dark Descent hits this case: a texturing instruction (4 components) gets rewritten to the gl_FragData output register (which was 4*3 = 12 components), causing the register allocator to hit the "we rely on split_virtual_grfs" assertion. This makes it possible to play Amnesia. Reviewed-by: Eric Anholt <[email protected]>
