I am trying to fine tune some code with inline assembly (__asm) in MSVC++ 1.52, but it will not let me use the FSIN, FCOS or FSINCOS floating point opcodes which are legal for the Pentium (and I believe the 486).  I have tried the /G3 flag, but it does not help.  Any suggestions?

I doubt that MSVC 1.52 even knows what a Pentium is, it is just
too old.
Though this is probably not what you want to hear, upgrading to
4.2 would be a good idea for you .....
