IndirectBranch Message in BTM mode #72

Closed Graf-Zahl closed 3 weeks ago

Graf-Zahl commented 1 month ago

In "7.3 . IndirectBranch Message" the first comment says that these kind of messages are applicable in BTM mode only. As far as I understood it, this is only true for "7.2 . DirectBranch Message".

Sorry, I was wrong in my last comment.

But maybe one could clarify that either IndirectBranch or IndirectBranchHist message should be send for certain itypes:

But for now I close the issue.
