36 This header defines macros with information about the C ABI.
37 Only information that can be determined using the preprocessor at
38 compilation time is available. No try-compile results may be added
39 here. Instead we memorize results on platforms of interest.
41 An includer may optionally define the following macros to suppress errors:
43 @KWIML@_ABI_NO_VERIFY = skip verification declarations
44 @KWIML@_ABI_NO_ERROR_CHAR_SIGN = signedness of 'char' may be unknown
45 @KWIML@_ABI_NO_ERROR_LONG_LONG = existence of 'long long' may be unknown
46 @KWIML@_ABI_NO_ERROR_ENDIAN = byte order of CPU may be unknown
48 An includer may test the following macros after inclusion:
50 @KWIML@_ABI_SIZEOF_DATA_PTR = sizeof(void*)
51 @KWIML@_ABI_SIZEOF_CODE_PTR = sizeof(void(*)(void))
52 @KWIML@_ABI_SIZEOF_FLOAT = sizeof(float)
53 @KWIML@_ABI_SIZEOF_DOUBLE = sizeof(double)
54 @KWIML@_ABI_SIZEOF_CHAR = sizeof(char)
55 @KWIML@_ABI_SIZEOF_SHORT = sizeof(short)
56 @KWIML@_ABI_SIZEOF_INT = sizeof(int)
57 @KWIML@_ABI_SIZEOF_LONG = sizeof(long)
59 @KWIML@_ABI_SIZEOF_LONG_LONG = sizeof(long long) or 0 if not a type
60 Undefined if existence is unknown and error suppression macro
61 @KWIML@_ABI_NO_ERROR_LONG_LONG was defined.
63 @KWIML@_ABI_SIZEOF___INT64 = 8 if '__int64' exists or 0 if not
64 Undefined if existence is unknown.
66 @KWIML@_ABI___INT64_IS_LONG = 1 if '__int64' is 'long' (same type)
68 @KWIML@_ABI___INT64_IS_LONG_LONG = 1 if '__int64' is 'long long' (same type)
70 @KWIML@_ABI___INT64_IS_UNIQUE = 1 if '__int64' is a distinct type
73 @KWIML@_ABI_CHAR_IS_UNSIGNED = 1 if 'char' is unsigned, else undefined
74 @KWIML@_ABI_CHAR_IS_SIGNED = 1 if 'char' is signed, else undefined
75 One of these is defined unless signedness of 'char' is unknown and
76 error suppression macro @KWIML@_ABI_NO_ERROR_CHAR_SIGN was defined.
78 @KWIML@_ABI_ENDIAN_ID_BIG = id for big-endian (always defined)
79 @KWIML@_ABI_ENDIAN_ID_LITTLE = id for little-endian (always defined)
80 @KWIML@_ABI_ENDIAN_ID = id of byte order of target CPU
81 Defined to @KWIML@_ABI_ENDIAN_ID_BIG or @KWIML@_ABI_ENDIAN_ID_LITTLE
82 unless byte order is unknown and error suppression macro
83 @KWIML@_ABI_NO_ERROR_ENDIAN was defined.
85 We verify most results using dummy "extern" declarations that are
86 invalid if the macros are wrong. Verification is disabled if
87 suppression macro @KWIML@_ABI_NO_VERIFY was defined.
