.BR \-fpu " fpu-mode"
This option is only available on x86 systems. This option takes the
values x87, sse2, or auto, with auto being the default. With the
default value, CMUCL will check to see if the machine running CMUCL
supports SSE2 or not. If so, the SSE2 core file is automatically
selected and used. If not, the x87 core file is used. With this
option, the user can override the detection and select a core. (Note
that you cannot run the SSE2 core on a chip that doesn't not have
SSE2. But the x87 core can run on any machine.)
