Subject: [edk2-devel] [RFC PATCH 1/1] BaseTools: drop tautological warning overrides for CLANGDWARF
Date: Wed, 23 Aug 2023 16:15:22 +0100 [thread overview]
Message-ID: <20230823151522.168518-1-quic_llindhol@quicinc.com> (raw)
The CLANGDWARF progfile sets both -Wno-tautological-compare and
-Wno-tautological-constant-out-of-range-compare, but this prevents
compile-time detection of certain errors.
Drop these flags.

Does anyone remember why these were added?
I'm not running into any issues across armvirtqemu, qemusbsa, ovmfx64, ovmfriscv64.
