This passes on amd64-linux where I'm testing my changes.

New Revision: 176900
URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=176900
Log:
Fix PR49876: Continue code generation with integer_zero_node on gloog_error
When setting gloog_error, graphite should continue code generation
without early returns, as otherwise the SSA representation would not
be complete. So set the new expression to integer_zero_node, that
would not require more SSA updates, and continue code generation as
nothing happened.
Regstrapped on amd64-linux.
2011-07-28 Sebastian Pop <sebastian.pop@amd.com>
PR tree-optimization/49876
* sese.c (rename_uses): Do not return false on gloog_error: set
the new_expr to integer_zero_node and continue code generation.
(graphite_copy_stmts_from_block): Remove early exit on gloog_error.
