If these are done correctly, cross compilers can be built. The host compiler and host operating system are also different, and are predefined by the host compiler. The ones used in dmd are: Macros defined by the compiler, not the code: Compiler: __DMC__ Digital Mars compiler _MSC_VER Microsoft compiler __GNUC__ Gnu compiler __clang__ Clang compiler Host operating system: _WIN32 Microsoft NT, Windows 95, Windows 98, Win32s, Windows 2000, Win XP, Vista _WIN64 Windows for AMD64 linux Linux __APPLE__ Mac OSX __FreeBSD__ FreeBSD __OpenBSD__ OpenBSD __sun Solaris, OpenSolaris, SunOS, OpenIndiana, etc For the target systems, there are the target operating system and the target object file format: Target operating system: TARGET_WINDOS Covers 32 bit windows and 64 bit windows TARGET_LINUX Covers 32 and 64 bit linux TARGET_OSX Covers 32 and 64 bit Mac OSX TARGET_FREEBSD Covers 32 and 64 bit FreeBSD TARGET_OPENBSD Covers 32 and 64 bit OpenBSD TARGET_SOLARIS Covers 32 and 64 bit Solaris It is expected that the compiler for each platform will be able to generate 32 and 64 bit code from the same compiler binary. Target object module format: OMFOBJ Intel Object Module Format, used on Windows ELFOBJ Elf Object Module Format, used on linux, FreeBSD, OpenBSD and Solaris MACHOBJ Mach-O Object Module Format, used on Mac OSX There are currently no macros for byte endianness order. */ #include #include #include #include #include #if IN_LLVM #include "llvm/ADT/Triple.h" #endif #ifdef __DMC__ #ifdef DEBUG #undef assert #define assert(e) (static_cast((e) || (printf("assert %s(%d) %s\n", __FILE__, __LINE__, #e), halt()))) #endif #endif #ifdef DEBUG #define UNITTEST 1 #endif void unittests();
