Fairly trivial patch that introduces no functional changes. * config/mips/mips.h (MIPS_STACK_ALIGN): Implement using ROUND_UP macro. * config/mips/mips.c (mips_setup_incoming_varargs): Use ROUND_DOWN to calculate off. (mips_gimplify_va_arg_expr): Use ROUND_UP to calculate rsize. (mips_emit_probe_stack_range): Use ROUND_DOWN to calculate rounded_size.
Tested by building a crosscompiler to powerpc64-linux-gnu. OK for mainline? Uros.
