Hi, We are using MPC 8541 processor. Running Linux 2.6.11. I have a question regarding unwinding stack frame in userland. To understand the stack frame format, I am using gdb to walk through nested function calls frame. I am not able to understand where the PC (program counter) of callee functions is saved on the stack/register. Here are my questions: 1- Is there any available software like "pstack" ported to powerpc that I can use? I know the stack pointer of the last frame is save in "R1" register. 2- How about PC, and number of the input parameters to the function. Many thanks in advance, BZ
