That now makes a difference since we perform bitfield lowering even when we do not actually if-convert the loop. if-conversion deals with resetting flow-sensitive info when necessary already. PR tree-optimization/112282 * tree-if-conv.cc (ifcvt_hoist_invariants): Only hoist from the loop header. * gcc.dg/torture/pr112282.c: New testcase.
