When migrating your application from big endian to little endian on the IBM POWER8 platform, there are a number of differences that need to be considered.  This can range from vectors, storage association between items of different sizes, long doubles, complex numbers, and serialization.  The IBM XL C/C++ for little endian Linux on Power Systems contains new options and built-in functions to help with your migration.  Here's a link to an article that will help you understand what to look out for and provide suggestions on code changes when porting your application.
