	* expr.c (expr): Assert on rankarg, not rank which can be unsigned.
	* read.c (read_a_source_file): Remove buffer_limit[-1] assertion.
	Don't skip over NUL char.
	(pseudo_set): Set X_op for registers to O_register.
	* symbols.c (symbol_clone): Remove assertion that sym is defined.
	(resolve_symbol_value): Resolve O_register symbols.
	* config/tc-i386.c (parse_real_register): Don't use i386_float_regtab.
	Instead find st(0) by hash lookup.
	* config/tc-ppc.c (ppc_macro): Warning fix.
opcodes/
	* i386-opc.c (i386_float_regtab, i386_float_regtab_size): Delete.
	Move contents to..
	(i386_regtab): ..here.
	* i386-opc.h (i386_float_regtab, i386_float_regtab_size): Delete.
