re PR tree-optimization/53265 (Warn when undefined behavior implies smaller iteration count)
PR tree-optimization/53265
* gcc.dg/graphite/scop-3.c (toto): Increase array size to avoid
undefined behavior.
* gcc.dg/graphite/id-6.c (test): Likewise.
* gcc.dg/graphite/pr35356-2.c: Adjust regexp patterns to only look for
MIN_EXPR and MAX_EXPR in GIMPLE stmts.
