* config/mn10300/mn10300.c: Include tm-constrs.h.
(struct liw_data): New data structure describing an LIW candidate
instruction.
(extract_bundle): Use struct liw_data. Allow small integer
operands for some instructions.
(check_liw_constraints): Use struct liw_data. Remove swapped
parameter. Add comments describing the checks. Fix bug when
assigning the source of liw1 to the source of liw2.
(liw_candidate): Delete. Code moved into extract_bundle.
(mn10300_bundle_liw): Use struct liw_data. Check constraints
before swapping.
* config/mn10300/predicates.md (liw_operand): New predicate.
Allows registers and small integer constants.
* config/mn10300/constraints.md (O): New constraint. Accetps
integers in the range -8 to +7 inclusive.
* config/mn10300/mn10300.md (movesi_internal): Add an alternative
for moving a small integer into a register. Give this alternative
LIW attributes.
(addsi3, subsi3, cmpsi, lshrsi3, ashrsi3): Likewise.
(ashlsi3): Likewise, plus give LIW attributes to the alternatives
using the J,K,L and M constraints,
(liw): Remove SI mode on second operands to allow for HI and QI
mode values.
(cmp_liw, liw_cmp): Likewise. Plus fix order of operands in the
instruction.
