◆ GCC_PRI64
| #define GCC_PRI64 HOST_LONG_LONG_FORMAT |
Provide C99 <inttypes.h> style format definitions for 64bits.
◆ GCC_PRISZ
| #define GCC_PRISZ "" |
Similarly format modifier for printing size_t. As not all hosts support
z modifier in printf, use GCC_PRISZ and cast argument to fmt_size_t.
So, instead of doing fprintf ("%zu\n", sizeof (x) * y); use
fprintf (HOST_SIZE_T_PRINT_UNSIGNED "\n",
(fmt_size_t) (sizeof (x) * y));
◆ HOST_BITS_PER_CHAR
| #define HOST_BITS_PER_CHAR CHAR_BIT |
HOST_WIDE_INT definitions for the GNU compiler. Copyright (C) 1998-2024 Free Software Foundation, Inc. This file is part of GCC. Provide definitions for macros which depend on HOST_BITS_PER_INT and HOST_BITS_PER_LONG.
This describes the machine the compiler is hosted on.

◆ HOST_BITS_PER_SHORT
| #define HOST_BITS_PER_SHORT (CHAR_BIT * SIZEOF_SHORT) |
◆ HOST_BITS_PER_WIDE_INT
| #define HOST_BITS_PER_WIDE_INT 64 |
If HAVE_LONG_LONG and SIZEOF_LONG_LONG aren't defined, but GCC_VERSION >= 3000, assume this is the second or later stage of a bootstrap, we do have long long, and it's 64 bits. (This is required by C99; we do have some ports that violate that assumption but they're all cross-compile-only.) Just in case, force a constraint violation if that assumption is incorrect.
Set HOST_WIDE_INT, this should be always 64 bits. The underlying type is matched to that of int64_t and assumed to be either long or long long.
