From a357d6273f796b384b7e36d58a8de947ebde9668 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 18 Nov 2024 08:45:16 -0300 Subject: [PATCH] math: Use atanf from CORE-MATH The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic atanf. The code was adapted to glibc style and to use the definition of math_config.h (to handle errno, overflow, and underflow). Benchtest on x64_64 (Ryzen 9 5900X, gcc 14.2.1), aarch64 (Neoverse-N1, gcc 13.3.1), and powerpc (POWER10, gcc 13.2.1): Latency master patched improvement x86_64 56.8265 53.6842 5.53% x86_64v2 54.8177
