* glsl: add ir_texture_samples texture opcodeIlia Mirkin2015-09-101-0/+1

| | | | | | | | | | | | | This was forgotten. I omitted the NULL check since we don't check ir_assignment::condition either.

* glsl: Modify ir_end_primitive to have a stream.Iago Toral Quiroga2014-06-301-0/+19
| | | | | | | This will be necessary to implement EndStreamPrimitive(). EndPrimitive() will produce an ir_end_primitive with the default stream 0. Reviewed-by: Chris Forbes <chrisf@ijw.co.nz>

| | | | | | | | | In these cases, we edit the list (or at least might be), so we use the foreach_list_safe variant. Signed-off-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Matt Turner <mattst88@gmail.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>
* glsl: Add support for specifying the component in textureGatherChris Forbes2013-10-061-1/+3
| | | | | | | | | | | ARB_gpu_shader5 introduces new variants of textureGather* which have an explicit component selector, rather than relying purely on the sampler's swizzle state. This patch adds the GLSL plumbing for the extra parameter. Signed-off-by: Chris Forbes <chrisf@ijw.co.nz> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

* glsl: Remove ir_print_visitor.h includes and usageEric Anholt2013-06-211-1/+0
| | | | | | | | | | | | | We have ir->print() to do the old declaration of a visitor and having the IR accept the visitor (yuck!). And now you can call _mesa_print_ir() safely anywhere that you know what an ir_instruction is. A couple of missing printf("\n")s are added in error paths -- when an expression is handed to the visitor, it doesn't print '\n' (since it might be a step in printing a whole expression tree).

* glsl: add support for ARB_texture_multisampleChris Forbes2013-03-021-0/+3
| | | | | | | | | | | | | | | | | | V2: - emit `sample` parameter properly for multisample texelFetch() - fix spurious whitespace change - introduce a new opcode ir_txf_ms rather than overloading the existing ir_txf further. This makes doing the right thing in the driver somewhat simpler. V3: - fix weird whitespace V4: - don't forget to include the new opcode in tex_opcode_strs[] (thanks Kenneth for spotting this) Signed-off-by: Chris Forbes <chrisf@ijw.co.nz> [V2] Reviewed-by: Eric Anholt <eric@anholt.net> [V2] Reviewed-by: Paul Berry <stereotype441@gmail.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>

* glsl: Change texel offsets to a single vector rvalue.Kenneth Graunke2011-01-311-0/+1
| | | | | | | | | | | Having these as actual integer values makes it difficult to implement the texture*Offset built-in functions, since the offset is actually a function parameter (which doesn't have a constant value). The original rationale was that some hardware needs these offset baked into the instruction opcode. However, at least i965 should be able to support non-constant offsets. Others should be able to rely on inlining and constant propagation.

I keep copy and pasting this code all over, so consolidate it in one place.
