[libc] Migrate sys/ tests to ErrnoCheckingTest. (#141871)

2025-05-29T05:18:22+00:00

See PR #132823 for a previous change to sys/epoll tests, and prior
changes before that.

ErrnoCheckingTest ensures that errno is properly reset at the beginning
of the test case, and is validated at the end of it. This change removes
many instances of manual errno manipulation.

[libc] Move libc_errno inside of LIBC_NAMESPACE (#80774)

2024-02-06T09:36:05+00:00

Having libc_errno outside of the namespace causes versioning issues when
trying to link the tests against LLVM-libc. Most of this patch is just
moving libc_errno inside the namespace in tests. This isn't necessary in
the function implementations since those are already inside the
namespace.

[libc] Cleanup ErrnoSetterMatcher target (#71240)

The ErrnoSetterMatcher target was renamed in a previous patch, but not
all uses were caught. This patch fixes those that remain.

[libc] Make ErrnoSetterMatcher handle logging floating point values.

2023-05-26T06:24:51+00:00

Along the way, couple of additional things have been done:

1. Move `ErrnoSetterMatcher.h` to `test/UnitTest` as all other matchers live
   there now.
2. `ErrnoSetterMatcher` ignores matching `errno` on GPUs.

[libc] Run all unit tests, irrespective of whether they belong to a test suite.

2023-04-24T22:37:58+00:00

Previously, only those unit tests which belonged to a suite were run as
part of libc-unit-tests. It meant that unit tests not part of any suite
were not being tested. This change makes all unit tests run as part of
libc-unit-tests. The convenience function to add a libc unit test suite
has been removed and add_custom_target is used in its place. One of the
bit-rotting test has along been fixed. Math exhaustive and differential
tests are skipped under full build.

[libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory.

2023-02-07T19:45:51+00:00

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.
