	* config/s390/s390.md ("tbegin", "tbegin_nofloat", "tbegin_retry")
	("tbegin_retry_nofloat", "tend", "tabort", "tx_assist"): Remove
	constraint letters from expanders.
	("tbegin_retry", "tbegin_retry_nofloat"): Change predicate of the
	retry count to general_operand.
	("tabort"): Give operand 0 a mode.
	("tabort_1"): Add mode and constraint letter for operand 0.
	* doc/extend.texi: Fix protoype of __builtin_non_tx_store.

2013-10-07  Andreas Krebbel  <Andreas.Krebbel@de.ibm.com>

	* gcc.target/s390/htm-1.c: Add more tests to cover different
	operand types.
