14 It is very important to use version control macros correctly - the
|
|
|
15 idea is that host and target are independent. If these are done
|
|
|
16 correctly, cross compilers can be built.
|
|
|
17 The host compiler and host operating system are also different,
|
|
|
18 and are predefined by the host compiler. The ones used in
|
|
|
19 dmd are:
|
|
|
20
|
|
|
21 Macros defined by the compiler, not the code:
|
|
|
22
|
|
|
23 Compiler:
|
|
|
24 __DMC__ Digital Mars compiler
|
|
|
25 _MSC_VER Microsoft compiler
|
|
|
26 __GNUC__ Gnu compiler
|
|
|
27 __clang__ Clang compiler
|
|
|
28
|
|
|
29 Host operating system:
|
|
|
30 _WIN32 Microsoft NT, Windows 95, Windows 98, Win32s,
|
|
|
31 Windows 2000, Win XP, Vista
|
|
|
32 _WIN64 Windows for AMD64
|
|
|
33 __linux__ Linux
|
|
|
34 __APPLE__ Mac OSX
|
|
|
35 __FreeBSD__ FreeBSD
|
|
|
36 __OpenBSD__ OpenBSD
|
|
|
37 __sun Solaris, OpenSolaris, SunOS, OpenIndiana, etc
|
|
|
38
|
|
|
39 For the target systems, there are the target operating system and
|
|
|
40 the target object file format:
|
|
|
41
|
|
|
42 Target operating system:
|
|
|
43 TARGET_WINDOS Covers 32 bit windows and 64 bit windows
|
|
|
44 TARGET_LINUX Covers 32 and 64 bit linux
|
|
|
45 TARGET_OSX Covers 32 and 64 bit Mac OSX
|
|
|
46 TARGET_FREEBSD Covers 32 and 64 bit FreeBSD
|
|
|
47 TARGET_OPENBSD Covers 32 and 64 bit OpenBSD
|
|
|
48 TARGET_SOLARIS Covers 32 and 64 bit Solaris
|
|
|
49
|
|
|
50 It is expected that the compiler for each platform will be able
|
|
|
51 to generate 32 and 64 bit code from the same compiler binary.
|
|
|
52
|
|
|
53 There are currently no macros for byte endianness order.
