Intel is extending the instruction set supported on new processors with the SSE4.1 and SSE4.2 instructions. These are defined in the Intel SSE4 Programming Reference available at <http://softwarecommunity.intel.com/isn/Downloads/Intel%20SSE4%20Programming%20Reference.pdf> (Reference Number: D91561-001; April 2007).
Solaris needs support for the following:
1. Detection of the availability of these instructions on a processor (CPUID). For example, "isainfo -x" should indicate the presence of the new instructions where available.
2. Disassembling of the new instructions using dis, mdb and libdisasm
