* config/s390/s390.md ("tmdi_reg", "tmsi_reg", "*movdi_64", "*movdi_31",
"iordi3"): Insns now use multiple letter constraints.
("*movdi_lhi", "*movdi_lli", "*movdi_lay"): Insns deleted. They are now
covered by "*movdi_64".
("*movsi_lhi", "*movsi_lli", "*movsi_lay"): Insns deleted. They are now
covered by "*movsi_zarch" and "*movsi_esa".
("*movsi_zarch", "*movsi_!zarch"): New insns.
("*llgt_sisi_split", "*llgt_didi_split"): Insns deleted. Now covered
by "*andsi3_zarch" and "anddi3".
("*anddi3_ni"): Insn merged with "anddi3".
("*andsi3_ni"): Insn merged with "*andsi3_zarch".
("*andsi3_zarch", "*andsi3_esa"): New insns.
("*iordi3_oi"): Insn merged with "iordi3".
("*iorsi3_oi"): Insn merged with "*iorsi3_zarch".
("*iorsi3_zarch", "*iorsi3_esa"): New insns.
* config/s390/s390.c (s390_single_qi, s390_single_hi): Functions
merged to s390_single_part.
(s390_single_part): New function.
NOTE: Semantics have changed a bit. Now the value of the part must
be different from the others to get a non-negative return value.
(s390_extract_qi, s390_extract_hi): Functions merged to
s390_extract_part.
(s390_extract_part, s390_extra_constraint_str,
s390_const_ok_for_constraint_p): New functions. The L constraint got a
new meaning and the N constraint was added as a multiple letter
constraint.
(s390_extra_constraint): Function deleted.
(print_operand): New output modifier 'i' and 'j' added.
All uses of CONST_OK_FOR_LETTER_P were replaced by
CONST_OK_FOR_CONSTRAINT_P.
* config/s390/s390-protos.h: Function prototypes adapted.
* doc/md.texi: Documentation for new constraint letters added.
