X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=8221f7855121073a39148fdcd99f3a4097f27396;p=openbsd

change constant handling with @l.
if the expected argument to the opcode is unsigned,
return (val & 0xffff)
if the expected argument to the occode is signed,
sign extend the 16 bit value
	short = val;
	val = (int) short;
