This is a small update of v7 addressing review comments from Jan and Pedro.
Jan agreed to implement "record goto" by directly navigating to the desired
instruction in the execution history. In particular, we do not use to_wait
and to_resume. This is similar to the implementation for s/w recording.
Markus Metzger (24):
btrace, linux: fix memory leak when reading branch trace
btrace: uppercase btrace_read_type
gdbarch: add instruction predicate methods
frame: add frame_is_tailcall function
frame: artificial frame id's
btrace: change branch trace data structure
record-btrace: fix insn range in function call history
record-btrace: start counting at one
btrace: increase buffer size
record-btrace: optionally indent function call history
record-btrace: make ranges include begin and end
btrace: add replay position to btrace thread info
target: add ops parameter to to_prepare_to_store method
record-btrace: supply register target methods
frame, backtrace: allow targets to supply a frame unwinder
record-btrace, frame: supply target-specific unwinder
record-btrace: provide xfer_partial target method
record-btrace: add to_wait and to_resume target methods.
record-btrace: provide target_find_new_threads method
record-btrace: add record goto target methods
record-btrace: extend unwinder
btrace, gdbserver: read branch trace incrementally
record-btrace: show trace from enable location
record-btrace: add (reverse-)stepping support
