      perf probe: Fix finder to find lines of given function · 0dbb1cac
      Masami Hiramatsu 提交于
      The commit ba28c59b fixed a declaration
      entry bug in probe_point_search_cb().  There are same bugs in line
      finder and call_probe_finder().  This introduces a new dwarf utility
      function to determine given DIE is a function definition, not
      declaration.

      perf tools: Fix buildid cache handling of kallsyms with kcore · 5b6a42fc
      Adrian Hunter 提交于
      When kallsyms is used with kcore the dso long_name becomes the kcore
      file name.  That prevents the buildid cache from caching kallsyms.
      (There is no support at present for caching kcore).  Fix by changing it
      so that the kallsyms name is used in that case instead.

      perf annotate: Fix objdump line parsing offset validation · 886b37ba
      Adrian Hunter 提交于
      When parsing lines from objdump a line containing source code starting
      with a numeric label is mistaken for a line of disassembly starting with
      a memory address.
      
      Current validation fails to recognise that the "memory address" is out
      of range and calculates an invalid offset which later causes this
      segfault:
      
      Program received signal SIGSEGV, Segmentation fault.
