Subject: 	* doc/invoke.texi: Document new MIPS -mllsc and -mno-llsc
 options. 	* doc/install.texi: Document new --with-llsc and
 --without-llsc 	options. 	* config.gcc: Handle --with-llsc and
 --without-llsc configure options. 	* config/mips/mips.md (sync,
 memory_barrier): Wrap sync instrunction 	in %| and %- operand codes. 
 Depend on GENERATE_SYNC instead of 	ISA_HAS_SYNC. 
 (sync_compare_and_swap<mode>, sync_add<mode>, sync_sub<mode>, 
 sync_old_add<mode>, sync_old_sub<mode>, sync_new_add<mode>, 
 sync_new_sub<mode>, sync_<optab><mode>, sync_old_<optab><mode>, 
 sync_new_<optab><mode>, sync_nand<mode>, sync_old_nand<mode>, 
 sync_new_nand<mode>, sync_lock_test_and_set<mode>): Depend on 	GENERATE_LL_SC
 instead of ISA_HAS_LL_SC. 	* config/mips/mips.opt (mllsc): New option. 
 * config/mips/mips.c (mips_llsc): Define variable. 	(mips_handle_option):
 Handle mllsc option. 	(override_options): Set mips_print_operand_punct for
 '|' and '-'. 	(print_operand): Add new %| and %- operand codes. 	*
 config/mips/mips.h (mips_llsc_setting): New enum type. 	(mips_llsc):
 Declare. 	(OPTION_DEFAULT_SPECS): Add llsc handling. 
 (GENERATE_SYNC): New macro. 	(GENERATE_LL_SC): New macro. 
 (MIPS_COMPARE_AND_SWAP, MIPS_SYNC_OP, MIPS_SYNC_OLD_OP, 
 MIPS_SYNC_NEW_OP, MIPS_SYNC_NAND, MIPS_SYNC_OLD_NAND, 	MIPS_SYNC_NEW_NAND,
 MIPS_SYNC_EXCHANGE): Wrap instructions 	in %| and %- operand codes.
