--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
So we simplify
if (iftmp.2_137 <= location_138)
..
else
{
_16 = (signed) prephitmp_15;
if (_16 < 0)
...
to
_192 = (signed) location_138;
if (0)
..
else
{
_16 = (signed) prephitmp_15;
if (_16 < 0)
...
and then thread - actually we have registered the forward thread already
and registered the block with the def of _192 as EDGE_NO_COPY_SRC_BLOCK
(because it was empty before). This is essentially a duplicate of PR102844
which has gone latent.
