[libc] Make fenv and math tests preserve fenv_t state (#89658) 2024-04-23T20:21:25+00:00 Roland McGrath mcgrathr@google.com 2024-04-23T20:21:25+00:00 837dab96d6f5bece79fd58d28ea2e6f7c0912493 This adds a new test fixture class FEnvSafeTest (usable as a base class for other fixtures) that ensures each test doesn't perturb the `fenv_t` state that the next test will start with. It also provides types and methods tests can use to explicitly wrap code under test either to check that it doesn't perturb the state or to save and restore the state around particular test code. All the fenv and math tests are updated to use this so that none can affect another. Expectations that code under test and/or tests themselves don't perturb state can be added later.

 [libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory. 2023-02-07T19:45:51+00:00 Siva Chandra Reddy sivachandra@google.com 2023-02-06T07:07:23+00:00 af1315c28f9bab76d3c2e1492a3d41e7c48215f8 This part of the effort to make all test related pieces into the `test` directory. This helps is excluding test related pieces in a straight forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move the MPFR wrapper and testutils into the 'test' directory.

[libc][nfc] move ctype_utils and FPUtils to __support 2021-08-06T17:29:41+00:00 Michael Jones michaelrj@google.com 2021-08-05T21:27:29+00:00 c120edc7b3e1907127c3107b30e2667f1fde1ee2 Some ctype functions are called from other libc functions (e.g. isspace is used in atoi). By moving ctype_utils.h to __support it becomes easier to include just the implementations of these functions. For these reasons the implementation for isspace was moved into ctype_utils as well. FPUtils was moved to simplify the build order, and to clarify which files are a part of the actual libc. Many files were modified to accomodate these changes, mostly changing the #include paths.
