Hi Robert, our case is the following we mmap the memory and save the pointer into a global variable, lets say "shm_ptr". Our XML then contains as address: address="shm_ptr+0x0FC0" The evaluation is done by gdb itself, you even convert all adresses to strings later which are basically mamroy expressions and there you can use your variables and arithmetic again :) Ty for considering this patch, if you have further questions or improvements, let me know! Best regards Martin
Add support for using expressions as register address
