[35/77] Add uses of as_a <scalar_int_mode>
This patch adds asserting as_a <scalar_int_mode> conversions to contexts in which the input is known to be a scalar integer mode. In expand_divmod, op1 is always a scalar_int_mode if op1_is_constant (but might not be otherwise). In expand_binop, the patch reverses a < comparison in order to avoid splitting a long line. gcc/ 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * cfgexpand.c (convert_debug_memory_address): Use as_a <scalar_int_mode>. * combine.c (expand_compound_operation): Likewise.
