    PR debug/55541
    * cp-tree.h (BLOCK_OUTER_CURLY_BRACE_P): Define.
    * decl.c (poplevel): If functionbody, try not to create an extra
    BLOCK for function body and use subblocks as that, if it is non-NULL
    and doesn't have siblings.  Set BLOCK_OUTER_CURLY_BRACE_P flag.
    (outer_curly_brace_block): Use BLOCK_OUTER_CURLY_BRACE_P flag.

    * g++.dg/debug/dwarf2/localclass3.C: Adjust for the extraneous
    DW_TAG_lexical_block removal.
    * g++.dg/debug/dwarf2/redeclaration-1.C: Likewise.
    * g++.dg/guality/pr55541.C: New test.
