* glsl: fix uniform linking logic in the presence of structsIlia Mirkin2015-02-193-31/+57
| | | | | | | | | | | | | Add a enter/leave record callback so that the offset may be aligned to the proper value. Otherwise only leaf fields are called, and the first field needs to be aligned to the outer struct's base alignment while the last field needs to be aligned to the inner struct's base alignment. This removes most usage of the last field/record type values passed into visit_field. Signed-off-by: Ilia Mirkin <[email protected]> Reviewed-by: Dave Airlie <[email protected]>

* nir: Conditionalize the POW reconstruction on shader compiler options.Eric Anholt2015-02-183-2/+6
| | | | | | | | | | | | | Mesa has a shader compiler struct flagging whether GLSL IR's opt_algebraic and other passes should try and generate certain types of opcodes or patterns.

* glsl: Reduce memory consumption of copy propagation passes.Kenneth Graunke2015-02-172-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | opt_copy_propagation and opt_copy_propagation_elements create new ACP and Kill sets each time they enter a new control flow block. For if blocks, they also copy the entire existing ACP set contents into the new set. When we exit the control flow block, we discard the new sets. However, we weren't freeing them - so they lived on until the pass finished. This can waste a lot of memory (57MB on one pessimal shader). This patch makes the pass allocate ACP entries using this->acp as the memory context, and Kill entries out of this->kill. It also steals kill entries when moving them from the inner kill list to the parent. It then frees the lists, including their contents. v2: Move ralloc_free(this->acp) just before this->acp = orig_acp (suggested by Eric Anholt).
