[dtrace-discuss] x64 SSE registers (xmm)

[Chris Kiick]

Hi,
    How do I examine what is in the %xmm registers on an x86 system? If a function
uses a double or float as an argument, it is not stored in the args array, instead it is passed
in the xmm registers.  The uregs[] array doesn't have them either. Can't find anything in the
docs.  What gives?
