Hi Christian, Yes, there is floating point precision related stuff, in the code on the very first line.
unsigned int cm = 0x27f; _FPU_SETCW(cm); This is done for all linux systems for achieving 64 bit floating point precision. So, do I need to ifdef it out for s390 or is there an alternative for it on s390x system? BTW, how did you match the spfc to user process fault, can you let me know about it, please? Thanks very much.
