* config/tc-ppc.c (md_pseudo_table): Add "bc" and "ec".
(ppc_stab_symbol): New static variable. (ppc_change_csect): Check that ppc_toc_csect is not NULL. (ppc_stabx): Set ppc_stab_symbol around call to symbol_make. Set sy_tc.real_name to the stab string. (ppc_bc, ppc_ec): New static functions. (ppc_canonicalize_symbol_name): If ppc_stab_symbol is set, don't do anything. (ppc_symbol_new_hook): If ppc_stab_symbol is set, don't look for a suffix.
