https://sourceware.org/gdb/wiki/Common describes the following
directory structure:
gdb/nat/
Native target backend files. Code that interfaces with the
host debug API. E.g., ptrace code, Windows debug API code,
procfs code should go here.
gdb/target/
Host-independent, target vector specific code (target_ops).
gdb/common/
All other shared code.
This commit moves all native target backend files currently in
gdb/common to gdb/nat.

This adds a "self" argument to to_supports_btrace. Due to how one
implementation of this method is shared with gdbserver this required a
small change to gdbserver as well.
2014-02-19 Tom Tromey <tromey@redhat.com>
* common/linux-btrace.c (linux_supports_btrace): Add "ops"
argument.
* common/linux-btrace.h (linux_supports_btrace): Update.
* remote.c (remote_supports_btrace): Add "self" argument.
* target-delegates.c: Rebuild.
* target.c (target_supports_btrace): Remove.
* target.h (struct target_ops) <to_supports_btrace>: Add
target_ops argument.
(target_supports_btrace): New define.

* target.h (struct target_ops) <supports_btrace>: Add target_ops
argument.
(target_supports_btrace): Update.

Read branch trace data incrementally and extend the current trace rather than
discarding it and reading the entire trace buffer each time.
If the branch trace buffer overflowed, we can't extend the current trace so we
discard it and start anew by reading the entire branch trace buffer.
2014-01-16 Markus Metzger <markus.t.metzger@intel.com>
