34
This header defines macros with information about the C ABI.
35
Only information that can be determined using the preprocessor at
36
compilation time is available.  No try-compile results may be added
37
here.  Instead we memorize results on platforms of interest.
38

39
An includer may optionally define the following macros to suppress errors:
40

41
  KWIML_ABI_NO_VERIFY          = skip verification declarations
42
  KWIML_ABI_NO_ERROR_CHAR_SIGN = signedness of 'char' may be unknown
43
  KWIML_ABI_NO_ERROR_LONG_LONG = existence of 'long long' may be unknown
44
  KWIML_ABI_NO_ERROR_ENDIAN    = byte order of CPU may be unknown
45

46
An includer may test the following macros after inclusion:
47

48
  KWIML_ABI_VERSION           = interface version number # of this header
49

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)
58

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.
62

63
  KWIML_ABI_SIZEOF___INT64    = 8 if '__int64' exists or 0 if not
64
    Undefined if existence is unknown.
65

66
  KWIML_ABI___INT64_IS_LONG   = 1 if '__int64' is 'long' (same type)
67
    Undefined otherwise.
68
  KWIML_ABI___INT64_IS_LONG_LONG = 1 if '__int64' is 'long long' (same type)
69
    Undefined otherwise.
70
  KWIML_ABI___INT64_IS_UNIQUE = 1 if '__int64' is a distinct type
71
    Undefined otherwise.
72

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.
77

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.
84

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.
