2025-10-21	[libc][math] Add tolerance to math tests so that they still work when ↵	lntue
	accurate path is skipped. (#164522)
2025-07-23	[libc][NFC] Add stdint.h proxy header to fix dependency issue with ↵	lntue
	<stdint.h> includes. (#150303) https://github.com/llvm/llvm-project/issues/149993
2024-10-05	[libc] remove errno.h includes (#110934)	Job Henandez Lara

2024-04-05	[libc] Add proxy header math_macros.h. (#87598)	lntue
	Context: https://github.com/llvm/llvm-project/pull/87017 - Add proxy header `libc/hdr/math_macros.h` that will: - include `<math.h>` 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`.
2024-03-18	[libc] Remove direct math.h includes (#85324)	Michael Jones
	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.
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.
2023-10-19	[libc][math][NFC] Remove global scope constants declaration in math tests ↵	lntue
	(#69558) Clean up usage of `DECLARE_SPECIAL_CONSTANTS` in global scope.
2023-09-26	[libc] Mass replace enclosing namespace (#67032)	Guillaume Chatelet
	This is step 4 of https://discourse.llvm.org/t/rfc-customizable-namespace-to-allow-testing-the-libc-when-the-system-libc-is-also-llvms-libc/73079
2023-06-01	[libc] Reduce math tests runtime	Guillaume Chatelet
	Reviewed By: lntue Differential Revision: https://reviews.llvm.org/D151798
2023-04-07	[libc][math] Update range reduction step for log10f and reduce its latency.	Tue Ly
	Simplify the range reduction steps by choosing the reduction constants carefully so that the reduced arguments v = r*m_x - 1 and v^2 are exact in double precision, even without FMA instructions, and -2^-8 <= v < 2^-7. This allows the polynomial evaluations to be parallelized more efficiently. Reviewed By: zimmermann6 Differential Revision: https://reviews.llvm.org/D147676
2023-02-10	[libc][math] Update exceptional cases for logf, log10f, log2f, log1pf.	Tue Ly
	Properly set floating point exceptions and add more exceptional values for non-FMA x86-64 targets. Reviewed By: michaelrj Differential Revision: https://reviews.llvm.org/D143699
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.
2022-01-25	[libc] Implement log10f correctly rounded for all rounding modes.	Tue Ly
	Based on RLIBM implementation similar to logf and log2f. Most of the exceptional inputs are the exact powers of 10. Reviewed By: sivachandra, zimmermann6, santoshn, jpl169 Differential Revision: https://reviews.llvm.org/D118093
