commit 766d05e2cabc44805a9e12c4c309d1232f681f10
Author: Mark Wielaard <mjw@redhat.com>
Date:   Tue Aug 18 22:01:53 2009 +0200

    Add testcase for PR10533 (inlined vars) and 10537 (inlined labels - disabled)
    
    Partial testcase for PR10533 (inlined vars) and 10537 (inlined labels)
    currently we cannot use the full testcase since stap doesn't support
    probing multiple instances of inlined labels.
    
    * testsuite/systemtap.base/inlinedvars.exp: New file.
    * testsuite/systemtap.base/inlinedvars.stp: Likewise.
    * testsuite/systemtap.base/inlinedvars.c: Likewise.

commit 7bce6f87482ece5b55db98b589666a2adac9cd1f
Author: Mark Wielaard <mjw@redhat.com>

    PR10533 inlined vars are not always found (dwflpp).
    
    dwflpp::find_variable_and_frame_base switched too early to "pyshical view"
    of die tree. We need to lookup the var in the "syntactical view" of the die
    tree first. Then when we see a DW_TAG_inlined_subroutine while walking the
    syntactical die tree as returned by dwarf_getscopes for a given variable
    to retrieve the frame base, then we need to switch to walking the physical
    die tree where the subroutine is inlined.
    
    * dwflpp.cxx (find_variable_and_frame_base): Don't immediately go to
      die_scopes, but lookup var first based on pc. Then switch "die branches"
      when searching for frame base and a DW_TAG_inlined_subroutine is
      encountered.

commit a2e0408065b872f8afac3364f218d9ebf9447dd1
Author: Mark Wielaard <mjw@redhat.com>
Date:   Tue Aug 18 21:52:59 2009 +0200

    PR10533 inlined vars are not always found (lo2c-test off-by-one).
    
    * loc2c-test.c (handle_variable): Set inner to zero after
      calling dwarf_getscopes_die(), for loop will increase inner.
