--- Comment #6 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
if (TREE_CODE (rhs_def_operand1) == SSA_NAME
&& ! SSA_NAME_OCCURS_IN_ABNORMAL_PHI (rhs_def_operand1)
&& TREE_CODE (rhs_def_operand2) == INTEGER_CST
&& operand_equal_p (rhs_def_operand2,
build_low_bits_mask (TREE_TYPE
(rhs_def_operand2),
TYPE_PRECISION (lhs_type)),
0))
in simplify_conversion_from_bitmask in tree-ssa-forwprop.c will need some
tweaking
