Alastair Donaldson	502e982956	spirv-fuzz: Fix to TransformationInlineFunction (#3913) ... This fixes a problem where TransformationInlineFunction could lead to distinct instructions having identical unique ids. It adds a validity check to detect this problem in general. Fixes #3911.	2020-10-16 22:58:09 +01:00
Alastair Donaldson	9edeeafdb6	spirv-fuzz: Use unique_ptr<FactManager> in TransformationContext (#3844) ... TransformationContext now holds a std::unique_ptr to a FactManager, rather than a plain pointer. This makes it easier for clients of TransformationContext to work with heap-allocated instances of TransformationContext, which is needed in some upcoming work.	2020-09-24 17:28:49 +01:00
Vasyl Teliman	36185f8b09	spirv-fuzz: Move IRContext parameter into constructor (#3837) ... This PR converts IRContext parameter in fact managers into a class field. Part of #3698.	2020-09-24 12:27:59 +01:00
Stefano Milizia	f62357e7b8	spirv-fuzz: Transformation to flatten conditional branch (#3667) ... This transformation, given the header of a selection construct with branching instruction OpBranchConditional, flattens it. Side-effecting operations such as OpLoad, OpStore and OpFunctionCall are enclosed within smaller conditionals. It is applicable if the construct does not contain inner selection constructs or loops, or atomic or barrier instructions. The corresponding fuzzer pass looks for selection headers and tries to flatten them. Needed for the issue #3544, but it does not fix it completely.	2020-09-15 10:31:01 +01:00
