Fri Jun 21 16:01:18 1996 Richard Henderson <rth@tamu.edu>

	* configure.in: Add alpha-*-linuxecoff* target.  Use elf for
	alpha-*-linux* target.  Force bfd_gas for alpha-*.  Require
	opcodes library for alpha.
	* configure: Rebuild with autoconf 2.10.
	* config/tc-alpha.c: Substantial rewrite to add ELF support and
	use new opcode table.
	* config/tc-alpha.h (md_undefined_symbol): Don't define.
	(LOCAL_LABEL): Define differently if OBJ_ELF.
	(FAKE_LABEL_NAME): Define if OBJ_ELF.
	* config/alpha-opcode.h: Remove.
	* config/obj-elf.h: If TC_ALPHA, define ECOFF_DEBUGGING.
	* Makefile.in (TARG_CPU_DEP_alpha): Depend upon
	include/opcode/alpha.h rather than config/alpha-opcode.h.
