[patch v9 00/23] branch tracing support for Atom

[Markus Metzger <markus dot t dot metzger at intel dot com>]

This is the full btrace series, now under the record command instead of an own
top-level command.

I dropped patches for the old btrace cli and corresponding tests.

Compared to the record-btrace mini-series, I now compute the function trace in a
single pass when reading the new branch trace.  This allows the "record
function-call-history" command to operate on a vector of functions and
simplifies the record-btrace code.  Some of the code has been moved from
record-btrace.c to btrace.c (the first patch of the series).

The patches have been committed into archer-mmetzger-btrace.  I just rebased the
series to the current head after updating archer.
