func()

int func	(		self,
		'mblock_t'	blk,
		'minsn_t'	ins,
		int	optflags )

Optimize an instruction. 

@param blk: current basic block. maybe nullptr, which means that the instruction must be optimized without context
@param ins: instruction to optimize; it is always a top-level instruction. the callback may not delete the instruction but may convert it into nop (see mblock_t::make_nop). to optimize sub-instructions, visit them using minsn_visitor_t. sub-instructions may not be converted into nop but can be converted to "mov x,x". for example: add x,0,x => mov x,x this callback may change other instructions in the block, but should do this with care, e.g. to no break the propagation algorithm if called with OPTI_NO_LDXOPT.
@param optflags: combination of optimization flags bits
@returns number of changes made to the instruction. if after this call the instruction's use/def lists have changed, you must mark the block level lists as dirty (see mark_lists_dirty)
