From 47a2a2303c9b261e88a4333bf2964b4291a22a12 Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Mon, 20 Apr 2009 22:43:37 +0200 Subject: Pass task from tapset, through stack and unwind functions for lookup. * 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. And add check and pass to unwind() and _stp_func_print(). * runtime/stack-x86_64.c: Likewise. * runtime/stack.c *_stp_stack_print): Take and pass on task_struct. (_stp_stack_snprint): Likewise. * runtime/unwind.c (unwind): Take and use task_struct for _stp_mod_sec_lookup(). * tapset/context-unwind.stp (print_backtrace): Pass NULL to _stp_stack_print(). (backtrace): Pass NULL to _stp_stack_snprint(). --- tapset/context-unwind.stp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'tapset/context-unwind.stp') diff --git a/tapset/context-unwind.stp b/tapset/context-unwind.stp index b3d19e29..f1e99dc8 100644 --- a/tapset/context-unwind.stp +++ b/tapset/context-unwind.stp @@ -28,7 +28,7 @@ */ function print_backtrace () %{ if (CONTEXT->regs) { - _stp_stack_print(CONTEXT->regs, 1, CONTEXT->pi, MAXTRACE); + _stp_stack_print(CONTEXT->regs, 1, CONTEXT->pi, MAXTRACE, NULL); } else { _stp_printf("Systemtap probe: %s\n", CONTEXT->probe_point); } @@ -42,7 +42,7 @@ function print_backtrace () %{ */ function backtrace:string () %{ /* pure */ if (CONTEXT->regs) - _stp_stack_snprint (THIS->__retvalue, MAXSTRINGLEN, CONTEXT->regs, 0, CONTEXT->pi, MAXTRACE); + _stp_stack_snprint (THIS->__retvalue, MAXSTRINGLEN, CONTEXT->regs, 0, CONTEXT->pi, MAXTRACE, NULL); else strlcpy (THIS->__retvalue, "", MAXSTRINGLEN); %} -- cgit
