* config/stormy16/stormy16-lib2.c (MIN_UNITS_PER_WORD): Provide a default definition. (LIBGCC2_UNITS_PER_WORD): Likewise. * config/stormy16/stormy16.c: Include df.h for the prototype for df_regs_ever_live_p. (xstormy16_expand_builtin_va_start): Convert the stack offset into a component_ref and then use POINTER_PLUS_EXPR to add it to the incoming_virtual_args_rtx. (xstormy16_gimplify_va_arg_expr): Rename to xstormy16_gimplify_va_arg_expr. Use POINTER_PLUS_EXPR when performing pointer arithmetic. (TARGET_GIMPLIFY_VA_ARG_EXPR): Use renamed xstormy16_gimplify_va_arg_expr. Fix up some formatting issues. * config/stormy16/stormy16.c: (xstormy16_carry_plus_operand): Move to predicates.md. (xs_hi_general_operand): Likewise. (xs_hi_nonmemory_operand): Likewise. * config/stormy16/predicates.md: (xstormy16_carry_plus_operand): New predicate. (xs_hi_general_operand): New predicate. (xs_hi_nonmemory_operand): New predicate. * config/stormy16/stormy16-protos.h: (xstormy16_carry_plus_operand): Delete prototype. (xs_hi_general_operand): Likewise. (xs_hi_nonmemory_operand): Likewise. * config/storm16/stormy16.md (addhi3): Remove earlyclobber modifiers as they are no longer needed and they can trigger reload spill failures. * config/storm16/stormy16.md (ineqbranchsi): Replace match_dup with a match_operand in order to help reload. * config/storm16/stormy16.md (movhi_internal): Replace 'r' constraint with 'e' for the 8th alternative as this version of the mov.w instruction only accepts the lower 8 registers.
