Determine Trace Encoding ISA

[Heiner Litz]

Hi 

I am using     dr_set_isa_mode(dcontext_, DR_ISA_REGDEPS, &dummy);

to successfully decode the Google memtraces encoded with the DR_ISA, but my program also ingests traces encoded with X86_ISA. Is there a way to determine for a given trace what ISA it has been encoded with, so I can set the decoder context accordingly?

The filetype record has the ISA:
