Hi All,
*Problem Statement :* We have stack unwinding code that relies on frame pointers. It not working in Optimized Code in Linux x86_64. *Reason :* Optimized gcc code (at any opt. level > 0) doesn't contain frame pointers on Linux x86_64.(Unless the architecture requires it for debugging on x86_64, like x86) I tried using, gcc building functions, but they also fails to get frame pointers, when code is compiled in optimized mode. http://gcc.gnu.org/onlinedocs/gcc/Return-Address.html http://www.gnu.org/software/libc/manual/html_node/Backtraces.html Can we use libelf and write frame-pointer traversal(downwards) routine on executable from given function? Do we need to include libdwarf and libunwind to traverse frame pointers. Please provide pointers regarding the same. If you are not right person working on such issues, then please provide reference so that I can reach out to them regarding the same. Thanks Pallav Singh
