Subject: [PATCH v1 25/25] ArmPkg: Fix Ecc error 5007 in DefaultExceptionHandlerLib
Date: Wed, 16 Dec 2020 17:22:00 +0000 [thread overview]
Message-ID: <20201216172200.25846-26-Pierre.Gondois@arm.com> (raw)
In-Reply-To: <20201216172200.25846-1-Pierre.Gondois@arm.com>
From: Pierre Gondois <Pierre.Gondois@arm.com>
This patch fixes the following Ecc reported error:
There should be no initialization of a variable as
part of its declaration
Fixing this error implies extracting the CpsrChar
array from CpsrString and making it a static variable.
Signed-off-by: Pierre Gondois <Pierre.Gondois@arm.com>
