commit 8cc799a5dece8e2358037a147458a5f9c3d9727a
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Jun 30 16:39:11 2010 -0700

    PR10943: support @entry saving in .return probes
    
    * staptree.h (struct entry_op): New.
    * parse.cxx (parse_entry_op): Parse @entry into an entry_op.
    * elaborate.cxx, staptree.cxx, translate.cxx: Add entry_op boilerplate.
    * tapsets.cxx (dwarf_var_expanding_visitor::visit_entry_op): New, save
      operand value using gen_mapped_saved_return.
      (dwarf_var_expanding_visitor::gen_mapped_saved_return): Use a new flag
      to see if the tid is already saved, because the add_block may have
      been created by gen_kretprobe_saved_return instead.
    * NEWS, stapprobes.3stap: Document it.
    * testsuite/sem*/entry*.stp: Test it.
