Subject: [PATCH v2 2/2] UefiCpuPkg/BaseUefiCpuLib: Use toolchain-specific rodata section name
Date: Mon, 9 Aug 2021 09:51:27 +0000 [thread overview]
Message-ID: <34c8c87e673ce08bef460179c5cb7b3ea9271208.1628502434.git.mhaeuser@posteo.de> (raw)
In-Reply-To: <252525969122e83d9fb9b83edc95c4f6dfd233b4.1628502434.git.mhaeuser@posteo.de>
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3318
Correctly define the read-only data sections with the
toolchain-specific section name. This hardens image permission
security and may save image space.
