...counter. The tool always assumes
that
the input assembly sequence is the body of a microbenchmark (a simple loop
executed for a number of iterations). The "next" instruction in sequence is
always the next instruction to dispatch.
Call instructions default to an arbitrary high latency of 100cy. A warning
is
generated if the tool encounters a call instruction in the sequence. Return
instructions are not evaluated, and therefore control flow is not affected.
However, the tool still queries the processor scheduling model to obtain
latency
information for instructions that affect the contro...
