Systems and methods for validating operation of a compiler are disclosed. One method includes receiving a definition of language syntax at an automated source code generator, and generating program code at the automated source code generator, the program code represented in source code including constructed self-validating code and syntactically-correct automatically generated code. The method also includes providing the source code to the compiler to be compiled into object code. Based on execution of the self-validating code as object code in a computing system, a computing system executing the object code outputs an indication of the correctness of compilation of the program code.
