WebSep 6, 2024 · Csmith is a random generator of C programs. It's primary purpose is to find compiler bugs with random programs, using differential testing as the test oracle. generator primary csmith Updated on Sep 6, 2024 C++ WebCSMITHEDGE probabilistically weakens the constraints used to enforce UB-freedom, thus generated programs are no longer guaranteed to be UB-free. It then employs several off-the-shelf UB detection tools and a novel dynamic analysis to (a) detect cases where the generated program exhibits UB and (b) determine where CSMITH has been too ...

The compiler follows a modular architecture, and can be seen as a sequence of source-to-source transformations applied to an intermediate representation … " - Csmithedge

WebOur CSMITHEDGEtool relaxes the analyses that CSMITHuses to ensure UB-freedom, and thus risks generating programs that exhibit UB. These must be detected, as they cannot be used for miscompilation testing. The following program analysers are employed for this purpose;theirroleinoursolutionissummarisedinTable1,whichwediscussinSection3.1.
