Subject: [PATCH v2 04/27] x86: Add macro to get symbol address for PIE support
Date: Tue, 13 Mar 2018 13:59:22 -0700 [thread overview]
Message-ID: <20180313205945.245105-5-thgarnie@google.com> (raw)
In-Reply-To: <20180313205945.245105-1-thgarnie@google.com>
Add a new _ASM_MOVABS macro to fetch a symbol address. It will be used
to replace "_ASM_MOV $<symbol>, %dst" code construct that are not compatible
with PIE.
