Stefano Milizia	43a5186011	spirv-fuzz: Compute interprocedural loop nesting depth of blocks (#3753) ... This PR extends CallGraph with functions to return: - a list of functions in lexicographical order, with respect to function calls - the maximum loop nesting depth that a function can be called from (computed interprocedurally, e.g. if foo() calls bar() at depth 2 and bar() calls baz() at depth 1, the maximum depth of baz() will be 3).	2020-09-01 12:23:58 +01:00
Alastair Donaldson	77fb303e58	spirv-fuzz: Fuzzer pass to add function calls (#3178) ... Adds a fuzzer pass that inserts function calls into the module at random. Calls from dead blocks can be arbitrary (so long as they do not introduce recursion), while calls from other blocks can only be to livesafe functions. The change fixes some oversights in transformations to replace constants with uniforms and to obfuscate constants which testing of this fuzzer pass identified.	2020-02-10 23:22:34 +00:00
