#ifndef __TARGETCONDITIONALS__

/****************************************************************************************************
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_MAC - Generated code will run under Mac OS X variant
TARGET_OS_OSX - Generated code will run under OS X devices
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_BRIDGE - Generated code will run under Bridge devices
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

NOTE: If your compiler errors out here then support for your compiler
has not yet been added to TargetConditionals.h.
TargetConditionals.h is designed to be plug-and-play. It auto detects
which compiler is being run and configures the TARGET_ conditionals
appropriately.
The short term work around is to set the TARGET_CPU_ and TARGET_OS_
on the command line to the compiler (e.g. -DTARGET_CPU_MIPS=1 -DTARGET_OS_UNIX=1)
The long term solution is to add a new case to this file which
auto detects your compiler and sets up the TARGET_ conditionals.
Then submit the changes to Apple Computer.
