[libc] Move libc_errno.h to libc/src/__support and make LIBC_ERRNO_MODE_SYSTEM to be header-only. (#143187)

2025-06-11T20:25:27+00:00

This is the first step in preparation for:

[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] Implement getitimer and setitimer, add proxy headers for itimerval (#134773)

[libc] Fix suseconds_t definition and utimes_test (#134326)

2025-04-04T19:53:46+00:00

The main issue was that the kernel expected `suseconds_t` to be 64 bits
but ours was 32. This caused inconsistent failures since all valid
`suseconds_t` values are less than 1000000 (1 million), and some
configurations caused `struct timeval` to be padded to 128 bits.

Also: forgot to use TEST_FILE instead of FILE_PATH in some places.

[libc] Make utimes_test more stable (#134321)

2025-04-03T23:53:55+00:00

The test for utimes added in #134167 might fail if the file for one test
hasn't been cleaned up by the OS before the second test starts. This
patch makes the tests use different files.

[libc] Implemented utimes (Issue #133953) (#134167)

2025-04-03T23:19:12+00:00

This pull request implements the `utimes` command in libc ([Issue
#133953](https://github.com/llvm/llvm-project/issues/133953)).

- [x] Add the implementation of `utimes` in `/src/sys/time`.
- [x] Add tests for `utimes` in `/test/src/sys/time`. 
- [x] Add `utimes` to
[entrypoints.txt](https://github.com/llvm/llvm-project/blob/main/libc/config/linux/x86_64/entrypoints.txt)
for at least x86_64 and whatever you're building on
- [x] Add `utimes` to
[include/sys/time.yaml](https://github.com/llvm/llvm-project/blob/main/libc/include/sys/time.yaml)
