Subject: [PATCH 21/26] ArmPlatformPkg/ArmJunoLib: switch to ASM_FUNC() asm macro
Date: Wed, 10 Aug 2016 17:17:57 +0200 [thread overview]
Message-ID: <1470842282-8415-22-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1470842282-8415-1-git-send-email-ard.biesheuvel@linaro.org>
Annotate functions with ASM_FUNC() so that they are emitted into
separate sections.
