Hi, Pls find the attached 3rd patch of the series: - [PATCH V2 3/3] - Cygwin: export sqrtl as alias to sqrt on AArch64
In-lined patch 3/3: From 9bdd0ee49375d842ff227c463194fb2ad9b84345 Mon Sep 17 00:00:00 2001 From: Thirumalai Nagalingam <thirumalai.nagalin...@multicorewareinc.com> Date: Wed, 27 Aug 2025 01:26:49 +0530 Subject: [PATCH 3/3] Cygwin: export sqrtl as alias to sqrt on AArch64 On AArch64, `long double` is the same as `double`, so `sqrtl` does not require a separate implementation in cygwin/math. Update `cygwin.din` to handle this correctly: - On AArch64: `sqrtl` is exported as an alias to `sqrt`. - On other architectures: `sqrtl` continues to export a separate implementation. This ensures the correct ABI while avoiding duplicate math implementations for equivalent types.
