From 3cb10cfafd83b9d7b3867b7deae29b8da3b5fe39 Mon Sep 17 00:00:00 2001 From: Christophe Lyon Date: Mon, 30 Apr 2018 10:03:43 +0200 Subject: linux-user: ARM-FDPIC: Add support of FDPIC for ARM. Add FDPIC info into image_info structure since interpreter info is on stack and needs to be saved to be accessed later on.
