Hi, I work on mips platform but there are some problem when I debug. GCC dispenses with the frame pointer and uses only the stack pointer, which changes during execution of the procedure. I can not get frame pointer to find ra and next frame. And I still not found good solution after I search from google. How do I traverse back to get the information about previous frame and the subsequent ? Is only way to use external GDB/ICE ? -- View this message in context: http://www.nabble.com/MIPS-backtrace-question-...-tf1965521.html#a5393776 Sent from the gcc - Help forum at Nabble.com.
