Hello,

I'm having a bit of an issue trying to get specific results from IDA's kernel.
Have been fumbling around with an 8bit MCU and am trying my hand at writing a custom proc module. things are working out so far but i'm having issues with printing labels vs. addr

Expected Output in IDA

Code:



ROM:BAB2                 jsr     LOC_B5DE

ROM:BAB8                 jsr     LOC_D3BA

but i'm getting absolute addresses instead labels. i am struggling trying to understand why it isn't working correctly. the book i'm following doesn't touch on using labels so I'm hoping someone here could point me in the right direction.

I think you want set_offset(...) or op_offset_ex(...) or op_offset(...), all in offset.hpp.

Maybe I'm still doing it wrong?

I ended up (thanks to _m for pointing this out) something like

Code:



if( get_name_expr(cmd.ea+x.offb, x.n, v, x.addr,buf,sizeof(buf), GETN_APPZERO) <= 0 )

{

    OutValue(x, OOF_ADDR | OOF_NUMBER | OOFS_NOSIGN | OOFW_32);

    QueueMark(Q_noName, cmd.ea);

    break;

}

OutLine(ptr);

the results i get are along the lines of what i'm trying to accomplish here (using labels vs. absolute addresses). seems i've got a few mistakes since I'm seeing labels being used in places they should be.
