2018-04-06	arch-arm: Add support for Tarmac trace generation	Giacomo Travaglini
	This patch introduces the TarmacTracer: an instruction tracer which allows to dump a gem5 execution trace in Tarmac format [1]. The new tracer is supporting either Tarmac and TarmacV8 format specifications. Not every traceable information has been implemented: Implemented Trace Type: Instruction Trace Register Trace Processor Memory Access Trace Unimplemented Trace Type: Program Flow Trace Event Trace Memory Bus Trace [1]: https://developer.arm.com/docs/dui0845/f/tarmac-trace-file-format Change-Id: I8799d8e5852e868673f728971db3fe8c63961f5e Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-on: https://gem5-review.googlesource.com/9382 Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>
2018-04-06	arch-arm: Add support for Tarmac trace-based simulation	Giacomo Travaglini
	A new InstTracer (TarmacParser) has been implemented. This tracer is parsing a pre-existing Tarmac trace file [1] while gem5 is running; it is comparing execution data together with trace data and it is dumping differences. This allows to use Tarmac format as a glue between heterogeneous simuators speaking the same Tarmac language. Kudos to Giacomo Gabrielli for writing the original tracer.
