sys/time.h.

* cpu.h (CONST_ATTRIBUTE): Define as __attribute__((__const__)) if

not already defined.
|

(cpu_system): Use CONST_ATTRIBUTE, so that when we're not inlining
|
||||
the world, the optimizer has a fair chance of CSE'ing function
|

calls.
|

(cpu_{monitor,nr,registers,model}): Ditto.
|

|

* std-config.h (MODEL_INLINE): If not defined, define as 1 if
|

DEFAULT_INLINE is non-zero, 0 otherwise, rather than just the
|
||||
value of DEFAULT_INLINE.
