2025-06-11[libc] Reduce direct use of errno in src/stdlib and src/__support tests. ↵Alexey Samsonov
(#143767) * 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 <stdlib.h> and for strdup from <string.h> to use ErrnoCheckingTest harness.
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.

2024-01-23[libc][NFC] Remove `FPBits` cast operator (#79142)Guillaume Chatelet
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.

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

2023-02-07[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.
2021-12-22[libc] apply formatting to testsMichael Jones
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. Reviewed By: sivachandra, lntue Differential Revision: https://reviews.llvm.org/D116127
2021-12-07[libc] apply new lint rulesMichael Jones
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.

2021-10-18[libc] add atof, strtof and strtodMichael Jones
Add the string to floating point conversion functions. Long doubles aren't supported yet, but floats and doubles are. The primary algorithm used is the Eisel-Lemire ParseNumberF64 algorithm, with the Simple Decimal Conversion algorithm as backup.
