2025-08-27	[libc][NFC] Fix Implicit Conversion Warning in getrandom Test (#155732)	Aiden Grossman
	getrandom returns a ssize_t, but the error codes are defined as integers. We need to use the builtin cast in the Fails matcher to ensure that everything is the same type. clang will warn about this in a bootstrapping build. Originally found in \#155627.
2025-05-28	[libc] Migrate sys/ tests to ErrnoCheckingTest. (#141871)	Alexey Samsonov
	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.

2024-02-06	[libc] Move libc_errno inside of LIBC_NAMESPACE (#80774)	michaelrj-google
	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.
2023-09-26	[libc] Mass replace enclosing namespace (#67032)	Guillaume Chatelet
	This is step 4 of https://discourse.llvm.org/t/rfc-customizable-namespace-to-allow-testing-the-libc-when-the-system-libc-is-also-llvms-libc/73079
2023-05-26	[libc] Make ErrnoSetterMatcher handle logging floating point values.	Siva Chandra Reddy
	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. Reviewed By: jhuber6 Differential Revision: https://reviews.llvm.org/D151129
2023-05-24	[libc] simplify test for getrandom	Guillaume Chatelet
	`getrandom` is implemented as a syscall. We don't want to test linux implementation of the syscall. We just want to verify that it reacts as expected to sensible values.

2023-04-12	[LIBC] Fix `getrandom` success return value	Noah Goldstein
	`getrandom` should return the number of bytes successfully set on success, not `0`. Reviewed By: sivachandra, michaelrj Differential Revision: https://reviews.llvm.org/D147981

2023-02-07	[libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory.	Siva Chandra Reddy
	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.
