Add a type_has_mode_precision_p helper function
...to replace instances of: TYPE_PRECISION (t) == GET_MODE_PRECISION (TYPE_MODE (t)) These conditions would need to be rewritten with variable-sized modes anyway. 2017-08-21 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree.h (type_has_mode_precision_p): New function. * convert.c (convert_to_integer_1): Use it. * expr.c (expand_expr_real_2): Likewise.
