Lowering return statements in gimple pass

[Olatunji Ruwase]

Hi,
 I have a question concerning the lowering of return statements during
the gimple pass.  Shouldnt the TREE_BLOCK () of the representative
return expr (which is moved to the end of the function) be updated to
reflect its new scope ?.
 Or on the other hand is TREE_BLOCK () intended to be an accurate
reflection of the lexical scope an expression belongs to ?.

Thanks
