Revert "[libc] Enable -Wconversion for tests. (#127523)"

2025-03-05T21:42:40+00:00

This reverts commit 1e6e845d49a336e9da7ca6c576ec45c0b419b5f6 because it
changed the 1st parameter of adjust() to be unsigned, but libc itself
calls adjust() with a negative argument in align_backward() in
op_generic.h.

[libc][math] fmod: clear exceptions before the test instead of after

2024-05-07T13:27:55+00:00

The test has no control over the CPU state before the test runs.

This test checks whether no exception flags are set, which may not be
true at the start of the test. This used to be not a problem because the
check was broken but that was fixed in ecfb5d9951554d8bdb6a499c958f48cc35f78a88

[libc] Make fenv and math tests preserve fenv_t state (#89658)

2024-04-23T20:21:25+00:00

This adds a new test fixture class FEnvSafeTest (usable as a base
class for other fixtures) that ensures each test doesn't perturb
the `fenv_t` state that the next test will start with.  It also
provides types and methods tests can use to explicitly wrap code
under test either to check that it doesn't perturb the state or
to save and restore the state around particular test code.

All the fenv and math tests are updated to use this so that none
can affect another.  Expectations that code under test and/or
tests themselves don't perturb state can be added later.

[libc] Add proxy header math_macros.h. (#87598)

2024-04-05T22:21:16+00:00

Context: https://github.com/llvm/llvm-project/pull/87017

- Add proxy header `libc/hdr/math_macros.h` that will:
  - include `` in overlay mode,
- include `"include/llvm-libc-macros/math-macros.h"` in full build mode.
- Its corresponding CMake target `libc.hdr.math_macros` will only depend
on `libc.include.math` and `libc.include.llvm-libc-macros.math_macros`
in full build mode.
- Replace all `#include "include/llvm-libc-macros/math-macros.h"` with
`#include "hdr/math_macros.h"`.
- Add dependency to `libc.hdr.math_macros` CMake target when using
`add_fp_unittest`.
- Update the remaining dependency.
- Update bazel overlay: add `libc:hdr_math_macros` target, and replacing
all dependency on `libc:llvm_libc_macros_math_macros` with
`libc:hdr_math_macros`.

[libc] Remove direct math.h includes (#85324)

2024-03-18T21:19:33+00:00

Reland of #84991

A downstream overlay mode user ran into issues with the isnan macro not
working in our sources with a specific libc configuration. This patch
replaces the last direct includes of math.h with our internal
math_macros.h, along with the necessary build system changes.

[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.
