Simon Marchi a154d838a7 gdb: add names to unwinders, add debug messages when looking for unwinder ... I wrote this while debugging a problem where the expected unwinder for a frame wasn't used. It adds messages to show which unwinders are considered for a frame, why they are not selected (if an exception is thrown), and finally which unwinder is selected in the end. To be able to show a meaningful, human-readable name for the unwinders, add a "name" field to struct frame_unwind, and update all instances to include a name. Here's an example of the output: [frame] frame_unwind_find_by_frame: this_frame=0 [frame] frame_unwind_try_unwinder: trying unwinder "dummy" [frame] frame_unwind_try_unwinder: no [frame] frame_unwind_try_unwinder: trying unwinder "dwarf2 tailcall" [frame] frame_unwind_try_unwinder: no [frame] frame_unwind_try_unwinder: trying unwinder "inline" [frame] frame_unwind_try_unwinder: no [frame] frame_unwind_try_unwinder: trying unwinder "jit" [frame] frame_unwind_try_unwinder: no [frame] frame_unwind_try_unwinder: trying unwinder "python" [frame] frame_unwind_try_unwinder: no [frame] frame_unwind_try_unwinder: trying unwinder "amd64 epilogue" [frame] frame_unwind_try_unwinder: no [frame] frame_unwind_try_unwinder: trying unwinder "i386 epilogue" [frame] frame_unwind_try_unwinder: no [frame] frame_unwind_try_unwinder: trying unwinder "dwarf2" [frame] frame_unwind_try_unwinder: yes gdb/ChangeLog: * frame-unwind.h (struct frame_unwind) <name>: New. Update instances everywhere to include this field. * frame-unwind.c (frame_unwind_try_unwinder, frame_unwind_find_by_frame): Add debug messages.
