dwarf2out.c (gen_enumeration_type_die): Remove unnecessary host_integerp test.
gcc/
* dwarf2out.c (gen_enumeration_type_die): Remove unnecessary
host_integerp test.
* tree-vect-patterns.c (vect_recog_divmod_pattern): Likewise.
Use TREE_INT_CST_LOW rather than tree_low_cst when reading the
constant.
* fold-const.c (fold_binary_loc): Replace a host_integerp/tree_low_cst
pair with a TREE_CODE test and TREE_INT_CST_LOW.
* tree-vect-generic.c (expand_vector_divmod): Likewise.
