| 39 | TARGET_CPU_* ␊ |
| 40 | These conditionals specify which microprocessor instruction set is being␊ |
| 41 | generated. At most one of these is true, the rest are false.␊ |
| 42 | ␊ |
| 43 | TARGET_CPU_PPC - Compiler is generating PowerPC instructions for 32-bit mode␊ |
| 44 | TARGET_CPU_PPC64 - Compiler is generating PowerPC instructions for 64-bit mode␊ |
| 45 | TARGET_CPU_68K - Compiler is generating 680x0 instructions␊ |
| 46 | TARGET_CPU_X86 - Compiler is generating x86 instructions␊ |
| 47 | TARGET_CPU_ARM - Compiler is generating ARM instructions␊ |
| 48 | TARGET_CPU_MIPS - Compiler is generating MIPS instructions␊ |
| 49 | TARGET_CPU_SPARC - Compiler is generating Sparc instructions␊ |
| 50 | TARGET_CPU_ALPHA - Compiler is generating Dec Alpha instructions␊ |
| 51 | ␊ |
| 52 | ␊ |
| 53 | TARGET_OS_* ␊ |
| 54 | These conditionals specify in which Operating System the generated code will␊ |
| 55 | run. The MAC/WIN32/UNIX conditionals are mutually exclusive. The EMBEDDED/IPHONE ␊ |
| 56 | ␉conditionals are variants of TARGET_OS_MAC. ␊ |
| 57 | ␊ |
| 58 | TARGET_OS_MAC - Generate code will run under Mac OS␊ |
| 59 | TARGET_OS_WIN32 - Generate code will run under 32-bit Windows␊ |
| 60 | TARGET_OS_UNIX - Generate code will run under some non Mac OS X unix ␊ |
| 61 | TARGET_OS_EMBEDDED - Generate code will run under an embedded OS variant␊ |
| 62 | of TARGET_OS_MAC␊ |
| 63 | TARGET_OS_IPHONE - Generate code will run under iPhone OS which ␊ |
| 64 | is a variant of TARGET_OS_MAC.␊ |
| 65 | ␊ |
| 66 | TARGET_RT_* ␊ |
| 67 | These conditionals specify in which runtime the generated code will␊ |
| 68 | run. This is needed when the OS and CPU support more than one runtime␊ |
| 69 | (e.g. Mac OS X supports CFM and mach-o).␊ |
| 70 | ␊ |
| 71 | TARGET_RT_LITTLE_ENDIAN - Generated code uses little endian format for integers␊ |
| 72 | TARGET_RT_BIG_ENDIAN - Generated code uses big endian format for integers ␊ |
| 73 | TARGET_RT_64_BIT - Generated code uses 64-bit pointers ␊ |
| 74 | TARGET_RT_MAC_CFM - TARGET_OS_MAC is true and CFM68K or PowerPC CFM (TVectors) are used␊ |
| 75 | TARGET_RT_MAC_MACHO - TARGET_OS_MAC is true and Mach-O/dlyd runtime is used␊ |
| 76 | ␊ |
