From 168234fa67c38f898b784b3265dd77ace0b0a2f9 Mon Sep 17 00:00:00 2001 From: Alex Richardson Date: Thu, 15 Apr 2021 16:27:52 +0100 Subject: [PATCH] lib/msun: Exclude ignored-pragmas from -Werror This avoids build failures due to the clang 12 warning: '#pragma FENV_ACCESS' is not supported on this target - ignored Clang 12 currently emits this warning for all non-x86 architectures. While this can result in incorrect code generation (e.g. on AArch64 some exceptions are not raised as expected), this is a pre-existing issue and we should not fail the build due to this warning.
