* i965/gen7.5: Allow HW primitive restart for all primitive types.Paul Berry2013-04-091-7/+6
| | | | | | | | | | | | | Gen7.5 (Haswell) hardware supports primitive restart for all primitive types. It also handles all possible primitive restart indices. Rather than specialize both can_cut_index_handle_restart_index() and the switch statement in can_cut_index_handle_prims() for Haswell, just return early if the hardware is Haswell because we know it can handle everything.

* i965: Only use brw_draw.c's trim() function when necessary.Paul Berry2013-04-091-2/+14
| | | | | | | | | | | | | | | | | | | | brw_draw.c contains a trim() function which modifies the vertex count for quads and quad strips in order to discard dangling vertices. In principle this shouldn't be necessary, since hardware since Gen4 is capable of discarding dangling vertices by itself. However, it's necessary because as a hack to speed up rendering on Gen 4-5, we sometimes convert quads to trifans and quad strips to tristrips. The trim() function isn't necessary on Gen6 and up. This patch documents why and when the trim() function is necessary, and avoids calling it when it's not needed. This will avoid creating problems when we enable hardware support for primitive restart of quads and quad strips on Haswell.

* glsl/linker: Reduce scope of non-flat integer varying fix.Paul Berry2013-04-091-4/+3
| | | | | | | | | | | | | | In the mailing list discussion of "glsl/linker: fix varying packing for non-flat integer varyings." (commit 7862bde), we concluded that since the bug only applies to integral variables, it is safer to just apply the bug fix to integer varyings. I forgot to make the change before pushing the patch upstream. (Note: we aren't aware of any bugs in commit 7862bde; it just seems wise to be on the safe side). This patch makes the change. Assuming commit 7862bde gets cherry-picked back to 9.1, this commit should be cherry-picked too. NOTE: This is a candidate for the 9.1 release branch.
* glsl/linker: Adapt flat varying handling in preparation for geometry shaders.Paul Berry2013-04-091-10/+20
| | | | | | | | | | | | | | | | When a varying is consumed by transform feedback, but is not used by the fragment shader, assign_varying_locations() sets its interpolation type to "flat" in order to ensure that lower_packed_varyings never has to deal with non-flat integral varyings (the GLSL spec doesn't require integral vertex outputs to be flat if they aren't consumed by the fragment shader). A similar situation will arise when geometry shader support is added, since the GLSL spec only requires integral vertex shader outputs to be flat when they are consumed by the fragment shader. This patch modifies the linker to handle this situation too. Reviewed-by: Jordan Justen <[email protected]>
* glsl: Document lower_packed_varyings' "flat" requirement with an assert.Paul Berry2013-04-091-0/+8
| | | | | | | | | | | | | To minimize the variety of type conversions that lower_packed_varyings needs to perform, it assumes that integral varyings are always qualified as "flat". link_varyings.cpp takes care of ensuring that this is the case (even in the circumstances where GLSL doesn't require it). This patch documents the assumption with an assertion, for ease in future debugging. Reviewed-by: Jordan Justen <[email protected]>
* glsl/linker: fix varying packing for non-flat integer varyings.Paul Berry2013-04-091-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit dfb57e7 (glsl: Fix error checking on "flat" keyword to match GLSL ES 3.00, GLSL 1.50) relaxed the rules for integral varyings: they only need to be declared as "flat" if they are a fragment shader inputs. This allowed for the possibility of a vertex shader output being a non-flat integer, provided that it was not matched to a fragment shader input. A non-contrived situation where this might arise is if a vertex shader generates some integral outputs which are consumed by tranform feedback, but not by the fragment shader. Unfortunately, lower_packed_varyings assumes that *all* integral varyings are flat, regardless of whether they are consumed by the fragment shader. As a result, attempting to create a non-flat integral vertex output of a size that required packing (i.e. a size other than ivec4 or uvec4) would cause an assertion failure in lower_packed_varyings. This patch prevents the assertion failure by forcing vertex shader outputs to be "flat" whenever they are not consumed by the fragment shader. This should have no effect on rendering since the "flat" keyword only affects the behaviour of fragment shader inputs. Fixes piglit test "spec/EXT_transform_feedback/nonflat-integral". NOTE: This is a candidate for the 9.1 release branch. Reviewed-by: Jordan Justen <[email protected]>

| | | | | | | | | ir_print_visitor::visit(ir_variable *)'s mode[] array needs to match the declaration of the enum ir_variable_mode.

| | | | | | | | | | | | This option can force textures to be untiled. However, on Gen6+, depth buffers must be Y-tiled. MSAA buffers also must be Y-tiled.

| | | | | | | | | | | | | | | | | In the past, we preferred X-tiling for color buffers because our BLT code couldn't handle Y-tiling. However, the BLT paths have been largely replaced by BLORP on Gen6+, which can handle any kind of tiling.

* glsl: Remove some unnecessary uses of error_emittedIan Romanick2013-04-081-15/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error_emitted flag is used in semantic checking to prevent spurious cascading errors. For example, void foo(sampler2D s, float a) { float x = a + (1.2 + s); ... } should only generate a single error. Without the error_emitted flag for the first error, "a + ..." would also generate an error. However, a bunch of cases in _mesa_ast_array_index_to_hir that were setting error_emitted would mask legitimate errors. For example, vec4 a[7]; float b = a[3.14]; should generate two error (float index and type mismatch in assignment). The uses of error_emitted would cause only the first to be emitted. This patch removes most of the places in _mesa_ast_array_index_to_hir that would set the error_emitted flag.
