Subject: [PATCH v3 3/7] ArmPkg/ArmSoftFloatLib: remove source files that are no longer used
Date: Fri, 31 May 2019 14:49:54 +0200 [thread overview]
Message-ID: <20190531124958.8421-4-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20190531124958.8421-1-ard.biesheuvel@linaro.org>
Now that we have switched to a new version of the SoftFloat code,
remove the source files that make up the old implementation, and
are no longer referenced.
