re PR tree-optimization/61684 (ICE at -Os and above on x86_64-linux-gnu in tree check: expected ssa_name, have addr_expr in recognize_single_bit_test, at tree-ssa-ifcombine.c:238)
PR tree-optimization/61684
* tree-ssa-ifcombine.c (recognize_single_bit_test): Make sure
rhs1 of conversion is a SSA_NAME before using SSA_NAME_DEF_STMT on it.
* gcc.c-torture/compile/pr61684.c: New test.
