-! Probe and instrument VIS1 instruction. Output is number of cycles it
-! takes to execute rdtick and pair of VIS1 instructions. US-Tx VIS unit
-! is slow (documented to be 6 cycles on T2) and the core is in-order
-! single-issue, it should be possible to distinguish Tx reliably...
-! Observed return values are:
-!
-! UltraSPARC IIe 7
-! UltraSPARC III 7
-! UltraSPARC T1 24
-!
-! Numbers for T2 and SPARC64 V-VII are more than welcomed.
-!
-! It would be possible to detect specifically US-T1 by instrumenting
-! fmul8ulx16, which is emulated on T1 and as such accounts for quite
-! a lot of %tick-s, couple of thousand on Linux...
