33        - SSE2 support added for x86.
34          o CMUCL automatically detects whether sse2 is supported or not
35            and loads up the appropriate core file.
36          o New -fpu switch allows the user to specify explicitly which
37            core should be used.
38          o Fasls compiled with sse2 support have the extension sse2f.
39            Otherwise, the normal x86f extension is used.  This allows the
40            user to do tests/experiments with both x87 and sse2 without
41            having to mess around with different directories and removing
42            fasls before building for a different FPU.
