Re: [PATCH] Check DECL_CONTEXT of new/delete operators.

[Jan Hubicka]

Hi,
thinking a bit of the problem, I guess we could match in addition to
DECL_CONTEXT the whole inline stack of both statements and see if there
are inlined new/delete operators and if so if they are always in
matching pairs.

The inline stack is available as
for (tree block = gimple_block (call); block && TREE_CODE (block) == BLOCK; 
block = BLOCK_SUPERCONTEXT (block))
  {
    tree fn = block_ultimate_origin (block);
    if (fn != NULL && TREE_CODE (fn) == FUNCTION_DECL)
      do the checking htere.
  }

But I do not understand what C++ promises here and in what conditions
the new/delete pair can be removed.
