--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Can you please narrow it down to a file and routine?  I guess I can look at it
afterwards using cross-compilers, the patch wasn't meant do any code generation
changes, only that sometimes a new stmt is created instead of reusing existing
one and the old one eventually removed later on, plus different SSA_NAME
versions may be used.  The only places where it should affect code generation
is if previously we kept invalid preserved range information (or we could have
wrong-debug) and something used that preserved range info, but in r203979 there
were still almost no get_range_info users.
