[PATCH v6 00/12] btrace: Turn linked list of function call segments into vector

[Tim Wiederhake <tim dot wiederhake at intel dot com>]

Hi all,

this series removes the extra list of btrace function call segments in struct
btrace_thread_info.  To achieve this, the doubly linked list of function call
segments in struct btrace_thread_info is replaced by a std::vector.

V1 of this series can be found here:
https://sourceware.org/ml/gdb-patches/2017-02/msg00482.html

V2 of this series can be found here:
https://sourceware.org/ml/gdb-patches/2017-05/msg00168.html

V3 of this series can be found here:
https://sourceware.org/ml/gdb-patches/2017-05/msg00202.html

V4 of this series can be found here:
https://sourceware.org/ml/gdb-patches/2017-05/msg00252.html

V5 of this series can be found here:
https://sourceware.org/ml/gdb-patches/2017-05/msg00284.html

Changes since V5:
* Changed comment in ftrace_new_function.
* Initialized fields in btrace_function directly.
* Put comment on btrace_thread_info::functions in a different patch.
* Replaced manual segment number <-> index calculation in record-btrace.c
* Reworked length check in ftrace_compute_global_level_offset.

V4 was ACK'd by Simon except for patch #12, which is addressed in V5 and V6.

The patches up to and including patch #6, "btrace: Remove constant arguments",
are unchanged since V4.

Regards,
Tim
