Alastair Donaldson	00170cc5e6	spirv-fuzz: Refactor 'copy object' and 'construct composite' transformations (#2966) ... Rework these transformations to identify instructions via (base, opcode, skip-count) triples, rather than (base, offset) pairs.	2019-10-15 20:00:17 +01:00
Alastair Donaldson	5910bb8e94	spirv-fuzz: add transformation and pass to construct composites (#2941) ... Adds a fuzzer pass and transformation to create a composite (array, matrix, struct or vector) from available constituent components, and inform the fact manager that each component of the new composite is synonymous with the id that was used to construct it. This allows the "replace id with synonym" pass to then replace uses of said ids with uses of elements extracted from the composite. Fixes #2858.	2019-10-08 14:04:10 +01:00
Alastair Donaldson	ad7f2c5c4c	Add fuzzer pass to copy objects (#2853) ... A new fuzzer pass that randomly introduces OpCopyObject instructions that make copies of ids, and uses the fact manager to record the fact that an id %id is synonymous with an id generated by an OpCopyObject applied to %id. (A future pass will exploit such synonym facts.)	2019-09-11 23:45:20 +01:00
