- Linux
- - A x86 or amd64 processor with support for sse2, sse3, and sse4.1 SIMD
- instructions. This is necessary because we emit several SSE intrinsics for
- convenience. See /proc/cpuinfo to know what your CPU supports.
+ - A x86 or amd64 processor. 64bit mode is preferred.
+
+ Support for sse2 is strongly encouraged. Support for ssse3, and sse4.1 will
+ yield the most efficient code. The less features the CPU has the more
+ likely is that you ran into underperforming, buggy, or incomplete code.

+ See /proc/cpuinfo to know what your CPU supports.
- LLVM 2.5 or greater. LLVM 2.6 is preferred.
