ARM traces with speculation information #27

Closed albertschulz closed 4 years ago

albertschulz commented 4 years ago

ETMv4 supports giving speculative information for program flow, but most implementation does not seem to support that, nor any traces containing these are existent in this repository. Do you know about implementations / architectures supporting that so we could enrich the testsuites?

Hi,

I.m adding in the Coresight mailing list in case anyone else has further information.

I am unaware of any current implementation available that has speculative trace.

The speculative trace support has been tested within ARM as part of internal architecture validation that is not available publicly.

Regards

Mike

Thanks for your information. Would be glad to be informed, if you get to know of any implementations.
