[pypy-issue] [issue1751] --jit-backend=x86-without-sse2 is broken

[Armin Rigo]

Armin Rigo <armin.rigo at gmail.com> added the comment:

It's unclear that we want to suffer having to think about non-SSE2 32-bit
machines now, when we have more or less moved toward optimizing code for 64-bit
first anyway.  Would it be good enough if pypy complained clearly when we start
it on a non-SSE2 machine?

Also note the command line on x86 Linux, which can be put in installation scripts:

if grep -q -w sse2 /proc/cpuinfo ; then echo "we have sse2"; fi
