title: Why does V8 in Node.js 0.12.0 release require SSE2 CPU instructions?
body: <p>Trying to upgrade Node.js from 0.10.x to 0.12.0. The first thing noticed is that I am getting an error that SSE2 instructions are not supported by my CPU (indeed they are not).</p>
  
  <p>Tried to compile Node.js from sources but it failed for the same reason. In <code>deps/v8/src/ia32/assembler-ia32.cc</code> there is a line stating</p>
  
  <pre><code>CHECK(cpu.has_sse2());  // SSE2 support is mandatory.
  </code></pre>
  
  <p>I wonder if there is a way to get rid of this SSE2 dependency which was not required in Node.js 0.10.x. Just commenting out this line does not help, it throws an <code>Illegal instruction</code> error during make process.</p>
