Subject: 	* config/tc-ppc.c (md_pseudo_table): Add "bc" and "ec".
X-Git-Tag: gdb-4_18~10336
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=31751d9d3ef22c725e7122b052ec29118f692ef8;p=platform%2Fupstream%2Fbinutils.git

	* 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.
