+	* config/tc-ppc.c (register_name,reg_name_search): Move register
+	name lookup from PE specific code to all targets.  Add support for
+	-mregnames/-mno-regnames to control whether register names are
+	expanded or not.
+	(md_assemble): Call register_name for all platforms.
+	(md_parse_option): Add support for -mregnames/-mno-regnames.
+
+	* configure.in (powerpcle*-*-solaris): Add support.
+	(powerpc*-*-linux): Ditto.
+	* configure: Regenerate.
+
+	* config/ppc-sol.mt: New config file for PowerPC Solaris.
