Predefined Macros for Power Architecture Compiler

As listed in the previous chapter, the compiler preprocessor has predefined macros. The macros in the previous chapter are available to all architecture. This chapter describes the predefined macros available specifically for the Power Architecture compiler.

• __ALTIVEC__
  Preprocessor macro defined if language extensions for using Power Architecture AltiVec™ instructions are available.
• __POWERPC__
  Preprocessor macro defined to describe the target powerpc processor.
• __PPCBROADWAY__
  Preprocessor macro defined if the compiler is generating object code for the Power Architecture "Broadway" processor.
• __PPCGECKO__
  Preprocessor macro defined if the compiler is generating object code for the Power Architecture "Gecko" processor.
• Processor Core Specific Macros
  macros specific to processor cores.
