Compiler validation is done during multiple stages of development: Precommit validation This validation is run before every commit to the code base.
All tests in the precommit test plan must pass before a commit is merged.
Nightly validations This is nightly integration testing, run every 24 hours.May 20, 2022.
Two main formal verification approaches for establishing correctness of compilation are proving correctness of the compiler for all inputs and proving correctness of a compilation of a particular program (translation validation)..
A compiler examines the source code and compares it to a list of grammar rules specific to the programming language written in to identify problems in the code.
The compiler will produce error messages that indicate the problems discovered, such as syntax mistakes, type mismatches, undeclared variables, etc..
The aim of compiler testing is to verify that the compiler implementation conforms to its specifications, which is to generate an object code that faithfully corresponds to the language semantic and syntax as specified in the language documentation..
Compilers analyze and convert source code written in languages such as Java, C++, C# or Swift.
They're commonly used to generate machine code or bytecode that can be executed by the target host system.
Interpreters do not generate IR code or save generated machine code..
The formal verification of a compiler is a radical solution to the miscompilation issue.
By applying formal methods (program proof) to the compiler itself, compiler verification proves, with mathematical certainty, that the generated executable code behaves exactly as prescribed by the semantics of the source program..
The purpose of validation, as a generic action, is to establish the compliance of any activity output as compared to inputs of the activity.
It is used to provide information and evidence that the transformation of inputs produced the expected and right result..
