Plum Hall is the world leader in making compiler validation suites and software for the programmer and software development community.
The Plum Hall Test Suites test for conformance of C and C++ compilers and libraries to ISO and ANSI standards as defined by the respective organizations. The test case suites are released every year in August, tracking conformance to the (developing) standards which are released on a 3 year basis. The Plum Hall Suites test against standards as they evolve for each standards release from C and C++-11, through C++-14, C++-17, C++20, C++23, and C++26 (proposed). The test suites evolve, tests being added, disabled, and modified as the standards evolve. Configuration options set testing to a particular standards year.
Reporting has also been improved. HTML Reports, which may be viewed in a web browser, are produced with each test run.
The 24a release of the Plum Hall Test Suites is available now. This release contains infrastructure improvements, bug fixes and preliminary tests for the proposed C++26 / C26 standards. Please see details here: 24a Release
