Function Documentation

CTRUMP_EXTDEF struct ctrump_expr* ctrump_peel_bitequality_cast_expr	(	struct ctrump_expr *	expr,
		const struct ctrump_abi *	abi
	)			[read]

remove cast if cast expr not convert bit-expression. ex) (unsigned int32) -> (int32) : remove (_Bool32) -> (int32) : remove

(int16) -> (int32) : not remove .. may cause sign extension (float32) -> (int32) : not remove (float64) -> (float32) : not remove (int32) -> (_Bool32) : not remove .. may cause boolean conversion (int32[4]) -> (int*) : not remove

Returns:
