Well, I was careful to write cross-platform C++ code from the start, meticulously isolating the few platform-specific parts. Yes, it's a lot to learn at start, but Powershell is rather user-friendly, so it helps. Yes, I work slower now

Oh. He used 14 registers to manually unroll the inner loop. IME, on modern architectures, manual unrolling doesn't win you anything (benchmarked on, among other things, the above-mentioned dotproduct). I wouldn't be surprised if h

A meta-comment on this: had this been a bug in VC people here would shit on Microsoft and their non-compliance to standards, not caring and so on and so on. But since it's in GCC, people are discussing a language feature.

What is the motivation behind this? Multi-CAS is used as a basic building block for lock-free data structures to emulate more complicated transactional operations. But when you already have TSX, why would you use multi-CAS to emulate them?
