MSP430: Implement TARGET_INSN_COST
The length of an insn can be used to calculate its cost, when optimizing
for size. When optimizing for speed, this is a good estimate, since the
cycle cost of an MSP430 instruction increases with its length.
gcc/ChangeLog:
* config/msp430/msp430.c (TARGET_INSN_COST): Define.
(msp430_insn_cost): New function.
* config/msp430/msp430.h (BRANCH_COST): Define.
(LOGICAL_OP_NON_SHORT_CIRCUIT): Define.
gcc/testsuite/ChangeLog:
* gcc.target/msp430/rtx-cost-O3-default.c: New test.
* gcc.target/msp430/rtx-cost-O3-f5series.c: New test.
* gcc.target/msp430/rtx-cost-Os-default.c: New test.
* gcc.target/msp430/rtx-cost-Os-f5series.c: New test.
