18 The macro `BITS64' can be defined to indicate that 64-bit integer types are
19 supported by the compiler.
20 -------------------------------------------------------------------------------
22 #define BITS64
25 -------------------------------------------------------------------------------
26 Each of the following `typedef's defines the most convenient type that holds
27 integers of at least as many bits as specified. For example, `uint8' should
28 be the most convenient type that can hold unsigned integers of as many as
29 8 bits. The `flag' type must be able to hold either a 0 or 1. For most
30 implementations of C, `flag', `uint8', and `int8' should all be `typedef'ed
31 to the same as `int'.
32 -------------------------------------------------------------------------------
34 typedef int flag;
35 typedef int uint8;
36 typedef int int8;
37 typedef int uint16;
38 typedef int int16;
39 typedef unsigned int uint32;
40 typedef signed int int32;
41 #ifdef BITS64
42 typedef unsigned long long int uint64;
43 typedef signed long long int int64;
44 #endif
47 -------------------------------------------------------------------------------
48 Each of the following `typedef's defines a type that holds integers
49 of _exactly_ the number of bits specified. For instance, for most
50 implementation of C, `bits16' and `sbits16' should be `typedef'ed to
51 `unsigned short int' and `signed short int' (or `short int'), respectively.
52 -------------------------------------------------------------------------------
54 typedef unsigned char bits8;
55 typedef signed char sbits8;
56 typedef unsigned short int bits16;
57 typedef signed short int sbits16;
58 typedef unsigned int bits32;
59 typedef signed int sbits32;
60 #ifdef BITS64
61 typedef unsigned long long int bits64;
62 typedef signed long long int sbits64;
63 #endif
65 #ifdef BITS64
67 -------------------------------------------------------------------------------
68 The `LIT64' macro takes as its argument a textual integer literal and
69 if necessary ``marks'' the literal as having a 64-bit integer type.
70 For example, the GNU C Compiler (`gcc') requires that 64-bit literals be
71 appended with the letters `LL' standing for `long long', which is `gcc's
72 name for the 64-bit integer type. Some compilers may allow `LIT64' to be
73 defined as the identity macro: `#define LIT64( a ) a'.
74 -------------------------------------------------------------------------------
76 #define LIT64( a ) a##LL
77 #endif
80 -------------------------------------------------------------------------------
81 The macro `INLINE' can be used before functions that should be inlined. If
82 a compiler does not support explicit inlining, this macro should be defined
83 to be `static'.

86 #define INLINE static inline
88 #define FLOAT64_DEMANGLE(a) (a)
89 #define FLOAT64_MANGLE(a) (a)
