(#157898) 2025-09-10T18:18:08+00:00 Alexey Samsonov vonosmas@gmail.com 2025-09-10T18:18:08+00:00 ccc340316ab94ee5370bb25c299851f3ee50cc4a This is one more follow-up to PR https://github.com/llvm/llvm-project/pull/157517 that cleans up the usage of libc_errno in math unit-tests (non-smoke). It follows the same rule: * if you use libc_errno in code literally, include src/__support/libc_errno.h * if you only rely on errno constants, include hdr/errno_macros.h Several tests for exp/log still retain the direct libc_errno usage, since in some cases they skip doing any validation if the error was raised. But the direct usage of libc_errno is removed from all other cases.

https://github.com/llvm/llvm-project/pull/157517 that cleans up the
usage of
libc_errno in math unit-tests (non-smoke). It follows the same rule:

* if you use libc_errno in code literally, include
src/__support/libc_errno.h
* if you only rely on errno constants, include hdr/errno_macros.h

Several tests for exp/log still retain the direct libc_errno usage,
since in some cases they skip doing any validation if the error was
raised. But the direct usage of libc_errno is removed from all other
cases.
