Test-Suite Extensions — LLVM 23.1.0 documentation

# Test-Suite Extensions

## Abstract

These are ideas for additional programs, benchmarks, applications and algorithms that could be added to the LLVM Test-Suite. The test-suite could be much larger than it is now, which would help us detecting compiler errors (crashes, miscompiles) during development.

Most probably, the reason why the programs below have not been added to the test-suite yet is that nobody has found time to do it. But there might be other issues as well, such as

> - Licensing (Support can still be added as external module,

>     like for the SPEC benchmarks)

> - Language (in particular, there is no official LLVM frontend

>     for FORTRAN yet)

> - Parallelism (currently, all programs in test-suite use

>     one thread only)

## Benchmarks

### SPEC CPU 2017

https://www.spec.org/cpu2017/

The following have not been included yet because they contain Fortran code.

In case of cactuBSSN only a small portion is Fortran. The hosts’s Fortran compiler could be used for these parts.

Note that CMake’s Ninja generator has difficulties with Fortran. See the CMake documentation for details.
