>From 9265cb96cc3129fada722d7195a1cf04e985ba33 Mon Sep 17 00:00:00 2001 From: s-watanabe314 <watanabe.shu...@fujitsu.com> Date: Fri, 14 Mar 2025 11:56:32 +0900 Subject: [PATCH 1/3] [Clang][Driver] Override complex number calculation method by -fno-fast-math This patch fixes a bug where -fno-fast-math doesn't revert the complex number calculation method to the default. The priority of overriding options related to complex number calculations differs slightly from GCC, as discussed in:
