compiler operations research


Hi,

Are there any known methodologies/tools/flows that enable operations
research on the compiler generated assembly?

The reasoning behind the question is that compiler heuristics
complexity are restricted by compilation time, while test environment
can run for a long time taking into account both intermediate outputs
of the different compilation stages and profiling of execution on real
targets.

The question does not relate to traditional profiler feedback
techniques which are usually restricted for the positioning of code
blocks/functions to minimize change of flow penalty but rather to the
ISA utilization (whether the correct instruction is utilized in the
correct places).

Thanks, Roy.
