==== 7.5.67 iushr ==== Logical shift right int Format iushr Forms iushr = 82 (0x52) Stack ..., value1.word1, value1.word2, value2.word1, value2.word2 -> ..., result.word1, result.word2 Description Both value1 and value2 must be of type int. The values are popped from the operand stack. An int result is calculated by shifting the result right by s bit positions, with zero extension, where s is the value of the low five bits of value2. The result is pushed onto the operand stack. Notes If value1 is positive and s is value2& 0x1f, the result is the same as that of value1 >> s; if value1 is negative, the result is equal to the value of the expression (value1 >> s) + (2 << ~s). The addition of the (2 << ~s) term cancels out the propagated sign bit. The shift distance actually used is always in the range 0 to 31, inclusive, as if value2 were subjected to a bitwise logical AND with the mask value 0x1f. If a virtual machine does not support the int data type, the iushr instruction will not be available.
