[libc] Reduce direct use of errno in src/stdlib and src/__support tests. (#143767)

2025-06-11T19:23:17+00:00

* Get rid of libc_errno assignments in str_to_* __support tests, since
those API have been migrated to return error in a struct instead.
* Migrate tests for atof and to strto* functions from  and for
strdup from  to use ErrnoCheckingTest harness.

[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] Add C23 limits.h header. (#78887)

[libc][NFC] Remove `FPBits` cast operator (#79142)

2024-01-23T16:30:19+00:00

The semantics for casting can range from "bitcast" (same representation)
to "different representation", to "type promotion". Here we remove the
cast operator and force usage of `get_val` as the only function to get
the floating point value, making the intent clearer and more consistent.

[libc] Mass replace enclosing namespace (#67032)

[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][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.

[libc] apply formatting to tests

2021-12-22T18:53:25+00:00

Apply the formatting rules that were applied to the libc/src directory
to the libc/test directory, as well as the files in libc/utils that are
included by the tests. This does not include automated enforcement.

[libc] apply new lint rules

2021-12-07T18:49:47+00:00

This patch applies the lint rules described in the previous patch. There
was also a significant amount of effort put into manually fixing things,
since all of the templated functions, or structs defined in /spec, were
not updated and had to be handled manually.
