SSE soft emulation for Linux?

[Jan Engelhardt]

Hi,


well as it happens, a user reported to me that some binary userspace 
blobs shipped with popular game servers crashes with Illegal 
Instruction. Upon review, the program tries to execute SSE code, which, 
of course, is bound to fail on older CPUs (see below for /proc/cpuinfo).

So I was wondering if there is an SSE emulation kit (for x86_32) similar 
to the FPU emu code for arch/x86/, to deal with such cases.
