This is a bigger update addressing Pedro's feedback.
I discarded my frame_id changes and instead use Pedro's unavailable stack
changes. See "frame: add frame_id_build_unavailable_stack_special".
The v8 "record-btrace: provide xfer_partial target method" patch did not
have any effect since the caller would simply continue with the target
beneath. I changed this to now throw an error if memory is not available.
To avoid issues with GDB trying to insert and remove breakpoints, this is
disabled for the duration of to_insert_breakoint and to_remove_breakpoint.
This needs a preparation patch "target, breakpoint: allow insert/remove
breakpoint to be forwarded" to allow ther espective target methods to be
forwarded.
I added a test covering the error on memory accesses to "record-btrace:
add (reverse-)stepping support".
The "frame, backtrace: allow targets to supply a frame unwinder" patch
has been split resulting in new patches "frame, cfa: check unwind stop
reason first" and "frame: do not assume unwinding will succeed".
A new patch "target: allow decr_pc_after_break to be defined by the target"
has been added to prepare for avoiding pc adjustments after break during
replay in "record-btrace: add (reverse-)stepping support".
This should also apply to the s/w record target but the condition under
which the pc needs to be adjusted is more complicated, here.
In "gdbarch: add instruction predicate methods" I added "::0" to the new
items I added to gdbarch.sh to fix an issue with verify_gdbarch.
There are lots of changes to all tests throughout the series plus a new
patch "btrace, test: fix multi-line btrace tests" to fix up existing tests.
Markus Metzger (29):
btrace, test: fix multi-line btrace tests
btrace, linux: fix memory leak when reading branch trace

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: provide xfer_partial target method
record-btrace: add to_wait and to_resume target methods.
