    hi,I have encountered a problem about branch delay slot.

     I do not want CPU to excute the instruction in branch delay slot ,and also,code-segment cannot be modified .

    I know one solution is use GCC marco -fno-delayed-branch to forbidden compiler insert other instructions to delay slot but NOP, but such solution need to re-compile code,it’s unacceptable in my project

     Thank you.

    There is not a possibility without re-compiling as the branch delay slots would have been filled during compilation.
