[Clang] Add predefined macros for integer constants (#123514)
This adds predefined macros for integer constants to implement section 7.18.4 of ISO/IEC 9899:1999 in `<stdint.h>` in a safe way: ``` __INT8_C(c) __INT16_C(c) __INT32_C(c) __INT64_C(c) __INTMAX_C(c) __UINT8_C(c) __UINT16_C(c) __UINT32_C(c) __UINT64_C(c) __UINTMAX_C(c) ``` Which improves compatibility with GCC and makes it trivial to implement section 7.18.4 of ISO/IEC 9899:1999. Clang defines `__INT<N>_C_SUFFIX__`, `__UINT<N>_C_SUFFIX__`, `__INTAX_C_SUFFIX__` and `__UINTMAX_C_SUFFIX__`, but these macros are useless for this purpose. Let's say, for example, that `__INT64_C_SUFFIX__` expands to `L` or `LL`. If the user defines them as a macros, the compiler will produce errors if `INT64_C` is implemented in `<stdint.h>` using `__INT64_C_SUFFIX__`: **minimal-test.c:** ```cpp #if defined(__clang__) & !defined(__INT64_C) # pragma clang diagnostic push # pragma clang diagnostic ignored "-Wreserved-identifier" # define __PSTDC_INT_C_(literal, suffix) literal##suffix # define __PSTDC_INT_C(literal, suffix) __PSTDC_INT_C_(literal, suffix) # define INT64_C(literal) __PSTDC_INT_C(literal, __INT64_C_SUFFIX__) # pragma clang diagnostic pop #elif defined(__GNUC__) # define INT64_C __INT64_C #endif typedef __INT64_TYPE__ int64_t; #define L "Make Clang produce an error" #define LL "Make Clang produce an error" int main(int argc, char **argv) { (void)argc; (void)argv; int64_t v = INT64_C(9223372036854775807); (void)v; return 0; } ``` <img width="697" alt="imagen" src="https://github.com/user-attachments/assets/6df97af6-7cfd-4cf9-85b7-d7c854509325" /> **test.c:** ```cpp #if defined(__clang__) && !defined(__INT8_C) # pragma clang diagnostic push # pragma clang diagnostic ignored "-Wreserved-identifier" # define __PSTDC_INT_C_(literal, suffix) literal##suffix # define __PSTDC_INT_C(literal, suffix) __PSTDC_INT_C_(literal, suffix) # define INT8_C(literal) __PSTDC_INT_C(literal, __INT8_C_SUFFIX__) # define INT16_C(literal) __PSTDC_INT_C(literal, __INT16_C_SUFFIX__) # define INT32_C(literal) __PSTDC_INT_C(literal, __INT32_C_SUFFIX__) # define INT64_C(literal) __PSTDC_INT_C(literal, __INT64_C_SUFFIX__) # define INTMAX_C(literal) __PSTDC_INT_C(literal, __INTMAX_C_SUFFIX__) # define UINT8_C(literal) __PSTDC_INT_C(literal, __UINT8_C_SUFFIX__) # define UINT16_C(literal) __PSTDC_INT_C(literal, __UINT16_C_SUFFIX__) # define UINT32_C(literal) __PSTDC_INT_C(literal, __UINT32_C_SUFFIX__) # define UINT64_C(literal) __PSTDC_INT_C(literal, __UINT64_C_SUFFIX__) # define UINTMAX_C(literal) __PSTDC_INT_C(literal, __UINTMAX_C_SUFFIX__) # pragma clang diagnostic pop #else # define INT8_C __INT8_C # define INT16_C __INT16_C # define INT32_C __INT32_C # define INT64_C __INT64_C # define INTMAX_C __INTMAX_C # define UINT8_C __UINT8_C # define UINT16_C __UINT16_C # define UINT32_C __UINT32_C # define UINT64_C __UINT64_C # define UINTMAX_C __UINTMAX_C #endif typedef __INT8_TYPE__ int8_t; typedef __INT16_TYPE__ int16_t; typedef __INT32_TYPE__ int32_t; typedef __INT64_TYPE__ int64_t; typedef __INTMAX_TYPE__ intmax_t; typedef __UINT8_TYPE__ uint8_t; typedef __UINT16_TYPE__ uint16_t; typedef __UINT32_TYPE__ uint32_t; typedef __UINT64_TYPE__ uint64_t; typedef __UINTMAX_TYPE__ uintmax_t; #define L "Make Clang produce an error" #define LL "Make Clang produce an error" #define U "Make Clang produce an error" #define UL "Make Clang produce an error" #define ULL "Make Clang produce an error" int main(int argc, char **argv) { (void)argc; (void)argv; int8_t a = INT8_C (127); int16_t b = INT16_C (32767); int32_t c = INT32_C (2147483647); int64_t d = INT64_C (9223372036854775807); intmax_t e = INTMAX_C (9223372036854775807); uint8_t f = UINT8_C (255); uint16_t g = UINT16_C (65535); uint32_t h = UINT32_C (4294967295); uint64_t i = UINT64_C (18446744073709551615); uintmax_t j = UINTMAX_C(18446744073709551615); (void)a; (void)b; (void)c; (void)d; (void)e; (void)f; (void)g; (void)h; (void)i; (void)j; return 0; } ```

- The builtin macros ``__INT8_C``, ``__INT16_C``, ``__INT32_C``, ``__INT64_C``,
483+
``__INTMAX_C``, ``__UINT8_C``, ``__UINT16_C``, ``__UINT32_C``, ``__UINT64_C``
484+
and ``__UINTMAX_C`` have been introduced to ease the implementaton of section
485+
7.18.4 of ISO/IEC 9899:1999. These macros are also defined by GCC and should
486+
be used instead of others that expand and paste the suffixes provided by
487+
``__INT8_C_SUFFIX__``, ``__INT16_C_SUFFIX__``, ``__INT32_C_SUFFIX__``,
488+
``__INT64_C_SUFFIX__``, ``__INTMAX_C_SUFFIX__``, ``__UINT8_C_SUFFIX__``,
489+
``__UINT16_C_SUFFIX__``, ``__UINT32_C_SUFFIX__``, ``__UINT64_C_SUFFIX__`` and
490+
``__UINTMAX_C_SUFFIX__``. Pasting suffixes after the expansion of their
491+
respective macros is unsafe, as users can define the suffixes as macros.
492+
482493
- Clang now rejects ``_BitInt`` matrix element types if the bit width is less than ``CHAR_WIDTH`` or
483494
not a power of two, matching preexisting behaviour for vector types.
