Branch instructions label
WebWhen a conditional or branch instruction is executed one of two things may happen. 1. If the test condition is true then the branch will be taken (see jump instructions). 2. If the test condition is false then nothing happens (see nop instruction). o This statement is not entirely accurate. Because the program counter always points to WebJul 8, 2024 · There's no label on it, so it's not a branch target you jump to from elsewhere. But if you're on real MIPS with branch-delay slots (the instruction after a branch executes even if the branch is taken), then b in the branch-delay slot of a beq leads to unpredictable behaviour. i.e. the b would run whether or not the branch was taken, making it ...
