* hwint.h (HOST_WIDE_INT_PRINT, HOST_WIDE_INT_PRINT_C): New macros. (HOST_WIDE_INT_PRINT_DEC_SPACE, HOST_WIDE_INT_PRINT_UNSIGNED_SPACE, HOST_WIDEST_INT_PRINT_DEC_SPACE, HOST_WIDEST_INT_PRINT_UNSIGNED_SPACE): Delete. (HOST_WIDE_INT_PRINT_DEC, HOST_WIDE_INT_PRINT_DEC_C, HOST_WIDE_INT_PRINT_UNSIGNED, HOST_WIDE_INT_PRINT_HEX): Define in terms of HOST_WIDE_INT_PRINT and possibly HOST_WIDE_INT_PRINT_C. * final.c (asm_fprintf): Use HOST_WIDE_INT_PRINT. * ra-debug.c (dump_static_insn_cost): Likewise.
