* glsl/linker: Ensure the first stage of an SSO pipeline has input locs assignedIan Romanick2016-05-181-3/+6
| | | | | | | | | | | | | | | | | | | | | Previously an SSO pipeline containing only a tessellation control shader and a tessellation evaluation shader would not get locations assigned for the TCS inputs. This would lead to assertion failures in some piglit tests, such as arb_program_interface_query-resource-query. That piglit test still fails on some tessellation related subtests. Specifically, these subtests fail: 'GL_PROGRAM_INPUT(tcs) active resources' expected 2 but got 3 'GL_PROGRAM_INPUT(tcs) max length name' expected 12 but got 16 'GL_PROGRAM_INPUT(tcs,tes) active resources' expected 2 but got 3 'GL_PROGRAM_INPUT(tcs,tes) max length name' expected 12 but got 16 'GL_PROGRAM_OUTPUT(tcs) active resources' expected 15 but got 3 'GL_PROGRAM_OUTPUT(tcs) max length name' expected 23 but got 12 Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Timothy Arceri <[email protected]> Cc: [email protected]
* glsl/linker: Don't include interface name for built-in blocksIan Romanick2016-05-181-1/+2
| | | | | | | | | | | | | | Commit 11096ec introduced a regression in some piglit tests (e.g., arb_program_interface_query-resource-query). I did not notice this regression because other (unrelated) problems caused failed assertions in those same tests on my system... so they crashed before getting to the new failure. v2: Use is_gl_identifier.

| | | | | | | | | | | | | | | Caller can pass a hashtable mapping NIR object (currently instr or var, but I guess others could be added as needed) to annotation msg to print inline with the shader dump.

* glsl: Don't do constant propagation in opt_constant_folding.Kenneth Graunke2016-05-152-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | opt_constant_folding is supposed to fold trees of constants into a single constant. Surprisingly, it was also propagating constant values from variables into expression trees - even when the result couldn't be folded together. This is opt_constant_propagation's job. The ir_dereference_variable::constant_expression_value() method returns a clone of var->constant_value. So we would replace the dereference with a constant, propagating it into the tree. Skip over ir_dereference_variable to avoid this surprising behavior. However, add code to explicitly continue doing it in the constant propagation pass, as it's useful to do so. shader-db statistics on Broadwell: total instructions in shared programs: 8905349 -> 8905126 (-0.00%) instructions in affected programs: 30100 -> 29877 (-0.74%) helped: 93 HURT: 20 total cycles in shared programs: 71017030 -> 71015944 (-0.00%) cycles in affected programs: 132456 -> 131370 (-0.82%) helped: 54 HURT: 45 The only hurt programs are by a single instruction, while the helped ones are helped by 1-4 instructions.

* glsl: Avoid excess tree walking when folding ir_dereference_arrays.Kenneth Graunke2016-05-151-0/+6
| | | | | | | | | | | | | | | | | | | If an ir_dereference_array has non-constant components, there's no point in trying to evaluate its value (which involves walking down the tree and possibly allocating memory for portions of the subtree which are constant). This also removes convoluted tree walking in opt_constant_folding(), which tries to fold constants while walking up the tree. No need to walk down, then up, then down again. We did this for swizzles and expressions already, but I was lazy back in the day and didn't do this for ir_dereference_array. No change in shader-db.

* nir: Add texture opcodes and source types for multisample compressionJason Ekstrand2016-05-142-0/+12
| | | | | | | | | | | Intel hardware does a form of multisample compression that involves an auxilary surface called the MCS. When an MCS is in use, you have to first sample from the MCS with a special opcode and then pass the result of that operation into the next sample instrucion. Normally, we just do this ourselves in the back-end, but we want to expose that functionality to NIR so that we can use MCS values directly in NIR-based blorp.
