* 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.
