Set on Less Than Immediate

Purpose:

Set on Less Than Immediate

To record the result of a less-than comparison with a constant.

Description: 

 GPR[rt] = (GPR[rs] < sign_extend(immediate) )

Compare the contents of GPR rs and the 16-bit signed immediate as signed integers; record the Boolean result of the comparison in GPR rt. If GPR rs is less than immediate, the result is 1 (true); otherwise, it is 0 (false).

The arithmetic comparison does not cause an Integer Overflow exception.

Restrictions:

None

Operation: 

if GPR[rs] < sign_extend(immediate) then
   GPR[rt] = 0GPRLEN-1|| 1
else
   GPR[rt] = 0GPRLEN
endif

Exceptions:

None
