This patch extends the other mode_supports* function to take an optional second argument to specificy particular reload register class, and it defaults to REG_RELOAD_ANY which says some reload register supports the feature. I have built bootstrap compilers with the first 4 patches including this patch on both big and little endian power8 systems. There were no regressions. 2018-03-21 Michael Meissner <meissner@linux.vnet.ibm.com> * config/rs6000/rs6000.c (mode_supports_pre_incdec_p): Add additional argument to specify the reload register class to use, defaulting to RELOAD_REG_ANY. (mode_supports_pre_modify_p): Likewise. (mode_supports_dq_form): Likewise. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meissner@linux.vnet.ibm.com, phone: +1 (978) 899-4797
