Browse Source 
2003-04-25  H.J. Lu <hjl@gnu.org>

	* config/ia64/ia64.c (ia64_expand_compare_and_swap): Add rmode
	for return mode.
	(ia64_expand_builtin): Set rmode to SImode for
	IA64_BUILTIN_BOOL_COMPARE_AND_SWAP_SI,
	IA64_BUILTIN_VAL_COMPARE_AND_SWAP_SI and
	IA64_BUILTIN_BOOL_COMPARE_AND_SWAP_DI. Set remode to DImode
	for IA64_BUILTIN_VAL_COMPARE_AND_SWAP_DI.
