After I did the build cleanup I wasn’t aware of your change to test specifically for SSE2. Thanks for the headsup. Previously it had been a check for SSE(MMX) to look for SSE2 capability. My apologies.

+#if USE_SSE2
+        "shl $26, %%eax\n\t"
+#else
         "shl $25, %%eax\n\t"
+#endif

Note that I've changed this recently so it does check for sse2 (if use_sse2 is
defined) and also it doesn't fallback gracefully if this check fails.

So we should probably build a sse2 build and a non-sse build (maybe a non-sse
build only occasionally?).
