Insert a jump instruction by using llvm pass-CodePudding

I want to insert a jump instruction into the target program through the pass of LLVM. I know that branchinst can be used to realize the jump of basic blocks in LLVM. But what I want to achieve is a jump of instructions in the same basic block (assuming I know the destination address of the jump). How do I do that? Iineasm? Can you give me an example?

For example, in C I could implement this:

// before insert jmp
#include <stdio.h>
int main()
{
    int a = 0;
    int b = 2;
    if(a<b)
    {
        printf("hh\n");
        printf("jump hh\n");
    }
    return 0;
}

result:  hh
         jump hh

// after insert jmp
#include <stdio.h>
int main()
{
    int a = 0;
    int b = 2;
    if(a<b)
    {
        asm("jmp main 0x30;");
        printf("hh\n");
        printf("jump hh\n");
    }
    return 0;
}

result:  jump hh

cmp    -0x4(%rbp),
