* glsl: teach copy_propagation_elements to deal with whole variablesCaio Marcelo de Oliveira Filho2018-07-271-29/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Keep information in acp_entry whether the entry is full or not, and use the ACP in more nodes when visiting the instructions: - add_copy: write whole variables to the ACP state (regardless the type). - visit(ir_dereference_variable *): perform the propagation here if we have a full candidate. Element-wise here doesn't apply because the mask isn't available at this point. - visit_leave(ir_assignment *): process beyond scalar and vector, as the full variables might have other types. Also import an improvement from opt_copy_propagation.cpp: if ir_call is an intrinsic, we know the variables affected, so keep going. v2: (all from Eric Anholt) Describe how acp_entry attributes are used. Don't do book-keeping to avoid adding repeated element to the dsts in write_elements(). v3: Use _mesa_set_remove_key.

* i965: Combine both gl_PatchVerticesIn lowering passes.Kenneth Graunke2018-07-262-7/+64
| | | | | | | | | | | | | | | | | | Until now, we had separate passes for lowering gl_PatchVerticesIn to a statically known constant (for TES inputs when linked against a TCS), and a uniform in the other cases. Annoyingly, one had to be run before nir_lower_system_values, and the other afterward. This simplified the passes, but made life painful for the callers. This patch combines both into a single pass. If you give it a non-zero static count, it uses that. If you give it Mesa state slots, it turns it back into a built-in uniform. Otherwise, it does nothing. This also moves the i965 uniform lowering out to shared code. v2: Make token arrays const. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | | | | | Python 2 has a range() function which returns a list, and an xrange() one which returns an iterator. Python 3 lost the function returning a list, and renamed the function returning an iterator as range(). As a result, using range() makes the scripts compatible with both Python versions 2 and 3.

* python: Better use iteratorsMathieu Bridon2018-07-242-3/+5
| | | | | | | | | | | | | | | | | In Python 2, iterators had a .next() method. In Python 3, instead they have a .__next__() method, which is automatically called by the next() builtin. In addition, it is better to use the iter() builtin to create an iterator, rather than calling its __iter__() method. These were also introduced in Python 2.6, so using it makes the script compatible with Python 2 and 3.

* glsl: don't let an 'if' then-branch kill copy propagation (elements) for ↵Caio Marcelo de Oliveira Filho2018-07-191-19/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | else-branch When handling 'if' in copy propagation elements, if a certain variable was killed when processing the first branch of the 'if', then the second would get any propagation from previous nodes. x = y; if (...) { z = x; // This would turn into z = y. x = 22; // x gets killed. } else { w = x; // This would NOT turn into w = y. } With the change, we let copy propagation happen independently in the two branches and only then apply the killed values for the subsequent code.

* glsl: change opt_copy_propagation_elements data structuresCaio Marcelo de Oliveira Filho2018-07-191-117/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of keeping multiple acp_entries in lists, have a single acp_entry per variable. With this, the implementation of clone is more convenient and now fully implemented. In the previous code, clone was only partial. Before this patch, each acp_entry struct represented a write to a variable including LHS, RHS and a mask of what channels were written to. There were two main hash tables, the first (lhs_ht) stored a list of acp_entries per LHS variable, with the values available to copy for that variable; the second (rhs_ht) was a "reverse index" for the first hash table, so stored acp_entries per RHS variable. After the patch, there's a single acp_entry struct per LHS variable, it contains an array with references to the RHS variables per channel. There now is a single hash table, from LHS variable to the corresponding entry. The "reverse index" is stored in the ACP entry, in the form of a set of variables that copy from the LHS. To make the clone operation cheaper, the ACP entries are created on demand. This should not change the result of copy propagation, a later patch will take advantage of the clone operation. v2: Add note clarifying how the hashtable is destroyed. v3: (all from Eric Anholt) Add remove_unused_var_from_dsts() function for reuse.
