Format:
TGEU rs, rt
Description:
The contents of general register rt are compared to the contents of general register rs. Considering both
quantities as unsigned integers, if the contents of general register rs are greater than or equal to the contents of
general register rt, a trap exception occurs.
The code field is available for use as software parameters, but is retrieved by the exception handler only by
loading the contents of the memory word containing the instruction.
Operation:
32, 64 T:
if (0 || GPR [rs]) > (0 || GPR [rt]) then

endif
