xxxx-xx-xx  Claudiu Zissulescu  <claziss@synopsys.com>

	* config/tc-arc.c (arc_select_cpu): Re-init the bfd if we change
	the CPU.
	* config/tc-arc.h: Add header if/defs.
	* testsuite/gas/arc/pseudos.d: Improve matching pattern.

xxxx-xx-xx  Claudiu Zissulescu  <claziss@synopsys.com>

	* Makefile.am: Remove earcelf_prof.c and earclinux_prof.c
	emulations.
	* Makefile.in: Regenerate.
	* configure.tgt: Likewise.
	* emulparams/arcelf_prof.sh: Remove file.
	* emulparams/arclinux_prof.sh: Likewise.
