* Detect kretprobe trampoline and use fallback unwinder.Mark Wielaard2009-06-031-3/+4
| | | | | | | | | | | | * runtime/sym.h (_stp_kretprobe_trampoline): Document. * translate.cxx (unwindsym_dump_context): Add stp_kretprobe_trampoline_addr. (dump_unwindsyms): Detect kretprobe_trampoline_holder symbol address. (emit_symbol_data): Initialize and emit _stp_kretprobe_trampoline. * runtime/transport/symbols.c (_stp_do_relocation): Detect kernel load address and adjust _stp_kretprobe_trampoline. * runtime/stack-i386.c (__stp_stack_print): Always use fallback unwinder when hitting kretprobe_trampoline_holder. * runtime/stack-x86_64.c (__stp_stack_print): Likewise.
* Don't use stack fallback for user space unwinding when using dwarf unwinder.Mark Wielaard2009-04-211-4/+8
| | | | | | | | It never seems to be anywhere near correct. * runtime/stack-i386.c (__stp_stack_print): Stop unwinding when dwarf unwinder fails and we are unwinding user space task. * runtime/stack-x86_64.c (__stp_stack_print): Likewise.
* Pass task from tapset, through stack and unwind functions for lookup.Mark Wielaard2009-04-201-4/+5
| | | | | | | | | | | | | | | | | * runtime/stack-arm.c (__stp_stack_print): Take struct task_struct *. * runtime/stack-ia64.c (__stp_stack_print): Likewise. * runtime/stack-ppc64.c (__stp_stack_print): Likewise. * runtime/stack-s390.c (__stp_stack_print): Likewise. * runtime/stack-i386.c (__stp_stack_print): Likewise.

* Use kernel stack backtrace support when availableTim Moore2009-02-111-0/+2
| | | | | Define new functions that use the kernel support to do a backtrace of other tasks than current.
