Alastair Donaldson	86d0d9be25	Refactored reducer so that the 'finding' functionality of a reduction pass are separated from the generic functionality for tracking progress of a pass. With this change, we now have a ReductionOpportunityFinder abstract class, with many subclasses for each type of reduction, and just one ReductionPass class, which has an associated finder. (#2321) ... Sounds good.	2019-01-23 17:07:58 -05:00
Alastair Donaldson	3d71024248	Added some documentation about the reducer. (#2318)	2019-01-23 12:29:14 -05:00
Paul Thomson	71aa48f91d	spirv-reduce: add OperandToUndefReductionPass (#2200) ... * Add OperandToUndefReductionPass. Fixes #2115. Also added some tests that are similar to those in OperandToConstantReductionPassTest. In addition, refactor FindOrCreateGlobalUndef into reduction_util.cpp. Fixes #2184. Removed many documentation comments that were identical or very similar to the overridden function's documentation comment.	2018-12-19 13:25:56 +00:00
Hugues Evrard	4aeadc0199	Add RemoveOpNameInstruction reduction pass (#2187) ... Add a spirv-reduce pass which removes OpName and OpMemberName instructions. This is useful to enable other reduction passes, e.g. RemoveUnreferencedInstruction may not be able to remove an instruction creating an id whose only usage is an OpName for this id.	2018-12-10 11:53:31 -05:00
Alastair Donaldson	6679d5df89	Replace loop with selection (#2164) ... Add a pass for spirv-reduce that will turn a loop into a selection.	2018-12-07 12:44:46 -05:00
Alastair Donaldson	3b13040cf9	New spirv-reduce reduction pass: operand to dominating id. (#2099) ... * Added a reduction pass to replace ids with ids of the same type that dominate them. * Introduce helper method for querying whether an operand type is an input id.	2018-11-26 17:06:21 -05:00
Alastair Donaldson	f3acb955c2	Initial commit for spirv-reduce. (#2056) ... Creates a new tool that can be used to reduce failing testcases, similar to creduce.	2018-11-21 14:03:09 -05:00
