2016-04-19tgsi/lowering: improved lowering for LRPRussell King1-35/+20
Provide an improved lowering for LRP, which can be implemented in two MAD instructions with a bit of rearranging of the equation, rather than the literal implementation of two multiplies, an add and a subtract.

2016-04-19tgsi/lowering: add support for lowering FLR and CEILRussell King2-20/+149
Add support for lowering FLR and CEIL to FRC/SUB and FRC/ADD instructions for GPUs that support FRC but not FLR or CEIL. Since these uses FRC, it is invalid to ask for FLR or CEIL to be lowered along with FRC, so add an assert to catch this invalid configuration. We also need to deal with FLR instructions emitted by the lowering code. Fix these up with the FRC+SUB equivalent when FLR lowering is enabled.

2016-03-31tgsi: split tgsi_util_get_texture_coord_dim() function into twoBrian Paul3-41/+38
It was kind of overloaded, returning two different things. Now get the index of the shadow reference src register with a new tgsi_util_get_shadow_ref_src_index() function. To verify the new code, I added some temp/debug code which looped over all TGSI_TEXTURE_x values, calling the old function and new and checking that the returned indexes matched. Also tested piglit "shadow" tests with softpipe/llvmpipe. No testing of ilo and radeonsi changes. Reviewed-by: Dave Airlie <airlied@redhat.com>

2016-03-30tgsi: (trivial) only verify target for is_tex instructionsRoland Scheidegger1-8/+7
d3d10 state tracker does not encode (valid) target (only offsets are really used from the texture bits), since that information always comes from the sview dcl, and not the instruction (note the meaning of target is actually slightly different between gl and d3d10 in any case, because d3d10 target does never include shadow bit). Also move the msaa sampler identification as well - would need to set that on the sview not sampler, so while this does not fix it make it at least obvious it won't work with sample instructions.

Texture sample instructions specify a sampler unit and texture target such as "1D", "2D", "CUBE", etc. Sampler view declarations also specify the sampler unit and texture target. This patch checks that the texture instructions agree with the declarations and collects the texture target type for each sampler unit. v2: only compare instruction's texture target to the sampler view declaration target if the instruction is a TEX instruction, not a SAMPLE instruction.

2016-03-21tgsi: Add support for global / private / input MEMORYHans de Goede5-20/+38
Extend the MEMORY file support to differentiate between global, private and shared memory, as well as "input" memory. "MEMORY[x], INPUT" is intended to access OpenCL kernel parameters, a special memory type is added for this, since the actual storage of these (e.g. UBO-s) may differ per implementation. The uploading of kernel parameters is handled by launch_grid, "MEMORY[x], INPUT" allows drivers to use an access mechanism for parameter reads which matches with the upload method.

2016-03-19gallium: add TGSI property NEXT_SHADERMarek Olšák3-0/+22
Radeonsi needs to know which shader stage will execute after a shader in order to make the best decision about which shader variant to compile first. This is only set for VS and TES, because we don't need it elsewhere. VS has 3 variants: - next shader is FS - next shader is GS - next shader is TCS TES has 2 variants: - next shader is FS - next shader is GS Currently, radeonsi always assumes the next shader is FS, which is suboptimal, since st/mesa always knows which shader is next if the GLSL program is not a "separate shader". By default, ureg always sets "next shader is FS". Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com>
