A structured, level-based training and testing suite designed to accelerate the development of code generators for new C compiler backends—ideal for compiler engineers building for new hardware targets.25 carefully designed incremental training levels ~1000 test files specifically structured for compiler backend development Begins with minimal setup (Level 0) and gradually builds toward full backend capability Covers key areas: arithmetic, pointers, register allocation, control flow, varargs, etc. Logical progression ensures steady skill and functionality ramp-up Seamlessly transitions into full SuperTest conformance suites Greatly reduces time to reach usable, testable compiler output Makes complex compiler backend development more systematic—and enjoyable Includes a free demo version with initial training levels.
