unconditional jump การใช้

• Conditional and Unconditional jumps as well as subroutines where supported.
• FCL has no concept of procedures, but does provide conditional and unconditional jumps.
• Three-address code may have conditional and unconditional jumps and methods of accessing memory.
• Register # 0 remains unchanged throughout calculations because it is used for the unconditional jump.
• This symbol, when executed as an instruction, causes an unconditional jump to location $ 3F5.
• On the KA10 and KI10, JRST is faster than JUMPA, so the standard unconditional jump is JRST.
• There was no unconditional jump instruction, nor was there a procedure call instruction-it had not yet been invented.
• It would eliminate a jump, but unconditional jumps are pretty cheap, and NOP slides aren't free either.
• Branch target prediction attempts to guess the target of a taken conditional or unconditional jump before it is computed by decoding and executing the instruction itself.
• To avoid unnecessary loading of branch prediction electronics, ( and therefore unnecessary pipeline stalls ) the comparing branch codes should never be used for unconditional jumps.
• The stack was flushed by an unconditional jump instruction, so unconditional jumps at the ends of loops were conventionally written as conditional jumps that would always succeed.
• The stack was flushed by an unconditional jump instruction, so unconditional jumps at the ends of loops were conventionally written as conditional jumps that would always succeed.
• The conditional skip operations compare register and memory contents and skip the next instruction ( which is often an unconditional jump ) depending on the result of the comparison.
• In particular, fall-through conditional branches must be changed to two-way branches, and function calls throwing exceptions must have unconditional jumps added after them.
• Instructions for the display processor consisted of 1-byte short-stroke instructions for letters and curves, and 6-byte long vector instructions, and 2-byte unconditional jumps.
• If particular implementation stops the computer if it encounters an unknown opcode or it implements additional unconditional jump instruction with opcode " 111aaaaa ", then such behaviour can be used as follows:
• Perhaps the reason Boolos-Burgess-Jeffrey clear r3 is to facilitate an unconditional jump to " loop "; this is often done by use of a dedicated register " 0 " that contains " 0 ":
• (Alternatively, the ] command may instead be translated as an unconditional jump "'to "'the corresponding [ command, or vice versa; programs will behave the same but will run more slowly, due to unnecessary double searching .)
• Above, the value of "-1 " found at address 31 can either be treated as invalid instruction causing the computer to stop or as unconditional jump ( BES 31 ) to the same address, resulting in infinite loop that does not affect the result ( control panel can be used to display it ).
• "' A plethora of instructions "': Because any instruction acting on a single register can be augmented with its indirect " dual " ( including conditional and unconditional jumps, cf the Elgot-Robinson model ), the inclusion of indirect instructions will double the number of single parameter / register instructions ( e . g.
