--- Comment #7 from Tulio Magno Quites Machado Filho <tuliom at ascii dot art.br> --- (In reply to HaoChen Gui from comment #6) > Does _ARCH_PWR8 impact anything during the compiling? I can answer this question from an user point of view. It's used in many projects to indicate if the target processor supports certain features, e.g. #ifdef _ARCH_PWR8 asm (...); /* Power8-specific code. */ #else /* Generic implementation. */ ... #endif
