Yeah I understand. :)

Reviewing what you can is appreciated. The code is here if it helps ..

Could you please check the PowerPC trampoline code ...

 https://git.rtems.org/chrisj/rtems.git/tree/cpukit/libdl/rtl-mdreloc-powerpc.c?h=libdl-epics-support#n169

Plus the other pieces of asm above I have added.

Thanks
