| 37 | * Basic macro definitions and redefinitions that support basic C types.
|
|---|
| 38 | *
|
|---|
| 39 | * Both GCC and clang define macros for fixed-size integer names
|
|---|
| 40 | * (e.g. __INT32_TYPE__ for int32_t). However, while clang also provides
|
|---|
| 41 | * definitions for formatting macros (PRId32 et al.), GCC does not.
|
|---|
| 42 | * This poses a subtle problem for diagnostics -- when 'int' and 'long int'
|
|---|
| 43 | * have the same width, it's not possible to detect which one is used to
|
|---|
| 44 | * define 'int32_t', but using a formatting specifier for 'int' on 'long int'
|
|---|
| 45 | * value, or vice versa, causes a compiler warning. Analogous problem occurs
|
|---|
| 46 | * with 'long int' and 'long long int', if they are the same size.
|
|---|
| 47 | *
|
|---|
| 48 | * In the interest of compatibility, we ignore the compiler's opinion on
|
|---|
| 49 | * fixed-size types, and redefine the macros consistently.
|
|---|
| 50 | *
|
|---|
| 51 | * However, we can't do the same for 'size_t', 'ptrdiff_t', 'wchar_t', 'wint_t',
|
|---|
| 52 | * 'intmax_t' and 'uintmax_t', since their format specifiers and other
|
|---|
| 53 | * properties are built into the language and their identity is therefore
|
|---|
| 54 | * determined by the compiler.
|
|---|
| 55 | *
|
|---|
| 56 | * We use some macros if they are present, but provide our own fallbacks when
|
|---|
| 57 | * they are not. There are several macros that have to be predefined either by
|
|---|
| 58 | * the compiler itself, or supplied by the build system if necessary
|
|---|
| 59 | * (e.g. using the '-imacros' compiler argument). This is basically a subset
|
|---|
| 60 | * of the common denominator of GCC and clang predefined macros at this moment.
|
|---|
| 61 | *
|
|---|
| 62 | * These required macros include:
|
|---|
| 63 | *
|
|---|
| 64 | * __CHAR_BIT__
|
|---|
| 65 | * __SIZEOF_SHORT__
|
|---|
| 66 | * __SIZEOF_INT__
|
|---|
| 67 | * __SIZEOF_LONG__
|
|---|
| 68 | * __SIZEOF_LONG_LONG__
|
|---|
| 69 | * __SIZEOF_POINTER__
|
|---|
| 70 | * __SIZEOF_FLOAT__
|
|---|
| 71 | * __SIZEOF_DOUBLE__
|
|---|
| 72 | * __SIZEOF_LONG_DOUBLE__
|
|---|
| 73 | *
|
|---|
| 74 | * __SIZE_TYPE__
|
|---|
| 75 | * __SIZE_MAX__
|
|---|
| 76 | *
|
|---|
| 77 | * __PTRDIFF_TYPE__
|
|---|
| 78 | * __PTRDIFF_MAX__
|
|---|
| 79 | *
|
|---|
| 80 | * __WCHAR_TYPE__
|
|---|
| 81 | * __WCHAR_MAX__
|
|---|
| 82 | *
|
|---|
| 83 | * __WINT_TYPE__
|
|---|
| 84 | * __WINT_MAX__ or
|
|---|
| 85 | * __WINT_WIDTH__ and __WINT_UNSIGNED__ when wint_t is unsigned
|
|---|
| 86 | *
|
|---|
| 87 | * __INTMAX_TYPE__
|
|---|
| 88 | * __INTMAX_MAX__
|
|---|
| 89 | * either __INTMAX_C_SUFFIX__ or __INTMAX_C
|
|---|
| 90 | *
|
|---|
| 91 | * __CHAR_UNSIGNED__ when char is unsigned
|
|---|
| 92 | *
|
|---|
| 93 | * After this header is processed, the following additional macros are
|
|---|
| 94 | * guaranteed to be defined, or the build will fail:
|
|---|
| 95 | *
|
|---|
| 96 | * for {type} being one of CHAR, SHRT, INT, LONG, LLONG
|
|---|
| 97 | * __{type}_MIN__
|
|---|
| 98 | * __{type}_MAX__
|
|---|
| 99 | * __U{type}_MAX__
|
|---|
| 100 | *
|
|---|
| 101 | * __SCHAR_MIN__
|
|---|
| 102 | * __SCHAR_MAX__
|
|---|
| 103 | *
|
|---|
| 104 | * for {size} being one of 8, 16, 32, 64, PTR, MAX
|
|---|
| 105 | * __INT{size}_TYPE__
|
|---|
| 106 | * __INT{size}_MIN__
|
|---|
| 107 | * __INT{size}_MAX__
|
|---|
| 108 | * __UINT{size}_TYPE__
|
|---|
| 109 | * __UINT{size}_MAX__
|
|---|
| 110 | * for {tag} being one of d, i, u, o, x, X
|
|---|
| 111 | * __PRI{tag}{size}__
|
|---|
| 112 | * for {tag} being one of d, i, u, o, x
|
|---|
| 113 | * __SCN{tag}{size}__
|
|---|
| 114 | * __INT{size}_C
|
|---|
| 115 | * __UINT{size}_C
|
