[Valgrind-users] SSE instruction?

[Jos v. d. O. <jos...@wu...>]

I'm trying to debug an OpenGL program on a Pentium IV with an NVidia 
Riva TNT2 graphics card. However valgrind from today's CVS on SuSE 8.2 
gives me this error:

disInstr: unhandled 2-byte opcode: 0x28 0x2 0xF
This _might_ be the result of executing a SSE, SSE2 or 3DNow!
instruction.  Valgrind does not currently support such instructions.  Sorry.
Aborted

Now I'm rather clueless about SSE, but I know 3DNow is Athlon specific. 
Is SSE Pentium related? Or is MMX not completely implemented yet?
