[15/77] Add scalar_int_mode
Similar to the previous scalar_float_mode patch, but for modes that satisfy SCALAR_INT_MODE_P. There are very many uses of scalar integers, so this patch only makes a token change to the types of byte_mode, word_mode, ptr_mode and rs6000_pmode. The next patches in the series gradually replace more uses. The patch also removes and adds casts to some target-specific code due to the new types of SImode, DImode and Pmode. The as_a <scalar_int_mode> goes away in a later patch. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * config/powerpcspe/powerpcspe.h (rs6000_pmode): Change type from machine_mode to scalar_int_mode. * config/powerpcspe/powerpcspe.c (rs6000_pmode): Likewise.
