128 bits integers are supported on x86. At least I have no problem
operate with them (using some intrinsics) and don't see any need in
another third-party library.
Very interesting. What compiler, what version?
I must say I've used rather old gcc 4.8 to try and it does support
int128 for x64 b ut does not support them for x86.
BTW, did you check native GCC's decfloat as well?
Yes, 2 years ago, and did not notice oerformance difference that time.
