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 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 __sun&&__SVR4 Solaris, OpenSolaris (yes, both macros are necessary) 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_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 and Solaris MACHOBJ Mach-O Object Module Format, used on Mac OSX There are currently no macros for byte endianness order. */ #include <stdio.h> #include <stdint.h> #include <stdarg.h> #include <stddef.h> #define __STDC_FORMAT_MACROS 1 #include <inttypes.h> #include <stdarg.h> #ifdef __DMC__ #ifdef DEBUG #undef assert #define assert(e) (static_cast<void>((e) || (printf("assert %s(%d) %s\n", __FILE__, __LINE__, #e), halt()))) #endif #endif #ifndef IS_PRINTF # ifdef __GNUC__ # define IS_PRINTF(FMTARG) __attribute((__format__ (__printf__, (FMTARG), (FMTARG)+1) )) # else # define IS_PRINTF(FMTARG) # endif #endif #ifdef IN_GCC /* Changes for the GDC compiler by David Friedman */ #endif #define DMDV2 0 // Version 2.0 features #define BREAKABI 1 // 0 if not ready to break the ABI just yet #define STRUCTTHISREF DMDV2 // if 'this' for struct is a reference, not a pointer #define SNAN_DEFAULT_INIT DMDV2 // if floats are default initialized to signalling NaN /* Other targets are TARGET_LINUX, TARGET_OSX, TARGET_FREEBSD and * TARGET_SOLARIS, which are * set on the command line via the compiler makefile. */ #if _WIN32 #define TARGET_WINDOS 1 // Windows dmd generates Windows targets #define OMFOBJ 1 #endif #if TARGET_LINUX || TARGET_FREEBSD || TARGET_SOLARIS #ifndef ELFOBJ #define ELFOBJ 1 #endif #endif #if TARGET_OSX #ifndef MACHOBJ #define MACHOBJ 1 #endif #endif struct Array;
