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(). --- runtime/unwind.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'runtime/unwind.c') diff --git a/runtime/unwind.c b/runtime/unwind.c index 7914c77d..aacd56f1 100644 --- a/runtime/unwind.c +++ b/runtime/unwind.c @@ -568,7 +568,7 @@ static char *_stp_eh_enc_name(signed type) /* Unwind to previous to frame.
