I took the time to finally get xptMiner to compile with GCC for Windows.
It was a nightmare for me, but what does that mean for you? Christmas may have come early.

I've compiled my optimized code for each of the following architectures: generic, core2, corei7, corei7-avx, k8, k8-sse3, and barcelona (k10).

The Windows x64 binaries are available from here:

Use whichever corresponds to your processor architecture.

If you're unsure, here's a quick guide based on your CPU manufacturer and age:
Intel: [Older] core2 -> corei7 -> corei7-avx [Newer]
AMD: [Older] k8 -> k8-sse3 -> barcelona (k10) [Newer]
Worst case scenario, use generic.

I will not be releasing any 32-bit builds. "High performance 32-bit" is an oxymoron.

Let me know what sort of improvements you see!
Some builds may be slightly slower than the stock jh00 miner. It all depends on your CPU.

I've added another 5-10% optimization to the code and hopefully fixed the issue with AMD builds.
It seems that mingw-gcc thinks that AMD processors don't support SSE, so it left them disabled. I've fixed that.

The code optimizations have been pushed to the github repo.
The new binaries have been uploaded. (same URLs)

More good news! I've added support for more processor architectures!
I've added support for core-avx-i (ivybridge), core-avx2 (haswell / 4th gen i7), bdver1 (Bulldozer), and bdver2 (Piledriver).

Also, the optimized miner now has it's own thread:

Hey hey! I've got an update on this little project.

I've made a few cache and memory tweaks and squeezed out another 5%.
I've also added AVX builds for Intel and AMD processors that support them. (I haven't fully tested these, so feedback is appreciated)

The changes have been pushed to github.
The files are now available for download.
