| /**************************************************************************************************** |
| |
| TARGET_CPU_* |
| These conditionals specify which microprocessor instruction set is being |
| generated. At most one of these is true, the rest are false. |
| |
| TARGET_CPU_PPC - Compiler is generating PowerPC instructions for 32-bit mode |
| TARGET_CPU_PPC64 - Compiler is generating PowerPC instructions for 64-bit mode |
| TARGET_CPU_68K - Compiler is generating 680x0 instructions |
| TARGET_CPU_X86 - Compiler is generating x86 instructions |
| TARGET_CPU_ARM - Compiler is generating ARM instructions |
| TARGET_CPU_MIPS - Compiler is generating MIPS instructions |
| TARGET_CPU_SPARC - Compiler is generating Sparc instructions |
| TARGET_CPU_ALPHA - Compiler is generating Dec Alpha instructions |
| |
| |
| TARGET_OS_* |
| These conditionals specify in which Operating System the generated code will |
| run. Indention is used to show which conditionals are evolutionary subclasses. |
| |
| The MAC/WIN32/UNIX conditionals are mutually exclusive. |
| The IOS/TV/WATCH conditionals are mutually exclusive. |
| |
| |
| TARGET_OS_WIN32 - Generated code will run under 32-bit Windows |
| TARGET_OS_UNIX - Generated code will run under some Unix (not OSX) |
| TARGET_OS_CYGWIN - Generated code will run under 64-bit Cygwin |
| TARGET_OS_MAC - Generated code will run under Mac OS X variant |
| TARGET_OS_IPHONE - Generated code for firmware, devices, or simulator |
| TARGET_OS_IOS - Generated code will run under iOS |
| TARGET_OS_TV - Generated code will run under Apple TV OS |
| TARGET_OS_WATCH - Generated code will run under Apple Watch OS |
| TARGET_OS_SIMULATOR - Generated code will run under a simulator |
| TARGET_OS_EMBEDDED - Generated code for firmware |
| |
| TARGET_IPHONE_SIMULATOR - DEPRECATED: Same as TARGET_OS_SIMULATOR |
| TARGET_OS_NANO - DEPRECATED: Same as TARGET_OS_WATCH |
| |
| TARGET_RT_* |
| These conditionals specify in which runtime the generated code will |
| run. This is needed when the OS and CPU support more than one runtime |
| (e.g. Mac OS X supports CFM and mach-o). |
| |
| TARGET_RT_LITTLE_ENDIAN - Generated code uses little endian format for integers |
| TARGET_RT_BIG_ENDIAN - Generated code uses big endian format for integers |
| TARGET_RT_64_BIT - Generated code uses 64-bit pointers |
| TARGET_RT_MAC_CFM - TARGET_OS_MAC is true and CFM68K or PowerPC CFM (TVectors) are used |
| TARGET_RT_MAC_MACHO - TARGET_OS_MAC is true and Mach-O/dlyd runtime is used |
