[libc] Fix math fuzzers (#101529)

2024-08-01T17:40:11+00:00

Fix minor typos that accumulated while the math fuzzers were disabled.

[libc] Fix the remaining isnan and isinf in tests. (#100969)

[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] Mass replace enclosing namespace (#67032)

[libc][Obvious][NFC] A bunch of cosmetic cleanup.

2021-11-19T17:02:55+00:00

* Added missing header guards.
* Fixed license header format in a few files.
* Renamed files to more suitable names.

[libc][nfc] move ctype_utils and FPUtils to __support

2021-08-06T17:29:41+00:00

Some ctype functions are called from other libc functions (e.g. isspace
is used in atoi). By moving ctype_utils.h to __support it becomes easier
to include just the implementations of these functions. For these
reasons the implementation for isspace was moved into
ctype_utils as well.

FPUtils was moved to simplify the build order, and to clarify which
files are a part of the actual libc.

Many files were modified to accomodate these changes, mostly changing
the #include paths.

[libc] Make FPBits a union.

2021-04-13T16:21:35+00:00

This helps us avoid the uncomfortable reinterpret-casts. Avoiding the
reinterpret casts prevents us from tripping the sanitizers as well.

[libc] Combine all math differential fuzzers into one target.

2020-11-20T15:46:15+00:00

Also added diffing of a few more math functions. Combining the diff check
for all of these functions helps us meet the OSS fuzz bar of a minimum of
100 program edges.
