void PrintC::opHiddenFunc ( const PcodeOp * op )

        off  yes       off   no        on  yes        on   no

		const Varnode *	vn,
		const PcodeOp *	op
	)

protectedvirtual

Push a constant with a floating-point data-type to the RPN stack.

The encoding is drawn from the underlying Translate object, and the print properties are checked for formatting overrides. In any case, a format is decided upon, and the constant is pushed as a single token.

Parameters

val	is the given encoded floating-point value
sz	is the size (in bytes) of the encoded value
vn	is the Varnode holding the value
op	is the PcodeOp using the value

void PrintC::push_integer	(	uintb	val,
		int4	sz,
		bool	sign,
		const Varnode *	vn,
		const PcodeOp *	op
	)

protectedvirtual

Push a constant with an integer data-type to the RPN stack.

Various checks are made to see if the integer should be printed as an equate symbol or if there is other overriding information about what format it should be printed in. In any case, a final determination of the format is made and the integer is pushed as a single token.

Parameters

val	is the given integer value
sz	is the size (in bytes) to associate with the integer
sign	is set to true if the integer should be treated as a signed value
vn	is the Varnode holding the value
op	is the PcodeOp using the value
