LIS25-232 Quality Assurance of Flang Using the Fujitsu Compiler Test Suite

• Thursday, 15 May 14:30 - 14:55
• Room: Session room 3 | Opala III

Flang, the Fortran compiler frontend in the LLVM Project, is under active development. However, the Flang/LLVM community lacked comprehensive Fortran test-suites, unlike those available for C/C++. This prevented rapid development of Flang without regressions. To address this, we started to make the test-suite for our proprietary Fortran/C/C++ compilers publicly available as Fujitsu Compiler Test Suite. In collaboration with Linaro, we implemented an open post-commit CI (continuous integration) system using the test-suite. At the same time, we analyzed the test-suite results and reported the identified bugs to the Flang community. These contributions significantly enhance quality of Flang and accelerate its development. This presentation details characteristics of the test-suite, its integration into an open post-commit CI system, our collaborative approach to bug fixing, achieved results, and future plans of the test-suite and the CI.
