From 15055a1cd7e2c249093a5f6d57eca817767d8b85 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 24 Sep 2012 17:52:18 -0400 Subject: [PATCH] ia64: define new get-rounding-mode.h header The new strtod function wants rounding information from the C lib, so move the guts of the ia64 version into a header file for it to use.
