+Subject: ARM EABI support - changes to existing ARM code
+Message-ID: <20050322160819.GA26216@nevyn.them.org>
+Mail-Followup-To: libc-alpha at sources dot redhat dot com,

+User-Agent: Mutt/1.5.6+20040907i
+
+This patch updates the common ARM files for EABI support.  The changes are:
+  - Old ARM ABI targets always use FPA (mixed-endian) byte ordering.  EABI
+    targets always use VFP byte ordering for doubles, which is standard
+    ieee754 layout.  Removing the arm-specific ieee754.h doesn't break FPA;
+    it was a specialized version of the common header, which handles FPA
+    but also handles VFP.
+  - The stack needs to be aligned to eight bytes instead of just four,
+    including in mmap2 and when shifting _dl_argv.
+  - We need some markers around _start to indicate end-of-stack for the
+    unwinder - ARM EABI does not use either SJLJ exceptions or DWARF-2
+    exceptions.  It uses a table based format which seems to be not
+    quite completely unlike DWARF-2.
+
+Do these changes look OK?
