I was wrong, Walter has given the right answer. The padding is compiler-specific. >which modern x86 hardware do not support the 80bit fpu type?< Current SSE registers, future AVX registers, all/most GPUs of the present. And take a look at the answer written by Don regarding 64 bit CPUs. LLVM doesn't like X86 FPU. Probaby 80 bit FPU type is not going away soon, but I don't think it's the future :-) >what implementation? of the software 128bit?< Yep. Bye, bearophile
