Vasyl Teliman	63cc22d645	spirv-fuzz: TransformationPropagateInstructionDown (#3692) ... Fixes #3691.	2020-10-06 13:38:19 +01:00
Alastair Donaldson	74a711a76d	spirv-fuzz: Only recommend passes when a pass had an effect (#3863) ... Fixes #3817.	2020-10-02 04:48:39 +01:00
Stefano Milizia	fc7860e2db	spirv-fuzz: Merge the return instructions in a function (#3838) ... This PR introduces TransformationMergeFunctionReturns, which changes a function so that it only has one reachable return statement. Fixes #3655.	2020-10-02 04:45:44 +01:00
Vasyl Teliman	615fbe6cbc	spirv-fuzz: TransformationWrapRegionInSelection (#3674) ... Fixes #3675.	2020-10-01 09:54:10 +01:00
Stefano Milizia	67525bded1	spirv-fuzz: Create synonym of int constant using a loop (#3790) ... This transformation, given a constant integer (scalar or vector) C, constants I and S of compatible type and scalar 32-bit integer constant N, such that C = I - S*N, adds a loop which subtracts S from I, N times, creating a synonym for C. The related fuzzer pass randomly chooses constants to which to add synonyms using this transformation, and the location where they should be added. Fixes #3616.	2020-09-23 14:10:02 +01:00
Alastair Donaldson	60ce96e2ff	spirv-fuzz: Add pass recommendations (#3757) ... This change introduces various strategies for controlling the manner in which fuzzer passes are applied repeatedly, including infrastructure to allow fuzzer passes to be recommended based on which passes ran previously.	2020-09-18 15:51:35 +01:00
