You'll need to implement it along the lines of x86. This could be done by looking for specific instructions on the stack (eg: ARM) or by recognizing dwarf unwind information (x86). The latter is a better method - but doesn't work on old glibcs with missing annotation. Also see dwarf/Gfde.c where dci->signal_frame is computed. -Arun _______________________________________________ Libunwind-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/libunwind-devel
