There is no good reason to use macros instead of static inline functions. The
current code is hard maintain. For example, it changes variables outside of the
macro scope. Also, it is conflicting with the C coding style.

The change [1] guarantees that the value pointed by 'prescaler'
gets always set, even when the adapter does not support the
specific mode requested (e.g. sync), or during trace disabling.
This works fine with the code in armv7m_trace_tpiu_config(), but
requires all the parameters to be valid also to disable the trace
(with 'enable==false'), otherwise returns error on incorrect
parameters or even causes segmentation fault if pointers
'trace_freq' or 'prescaler' are NULL.
Another problem in stlink_config_trace(), not linked with [1], is
caused by a tentative to change the settings on an already enabled
trace; the trace is disabled before the new parameters are fully
validated and in case of invalid parameters the trace is not
re-enabled.
It would be more logical to first check all the parameters, then
disable the trace, change the settings and re-enable the trace.
Practically revert [1] by checking 'enable==false' at function
entry, then disable trace and exit without any further check on
the other parameters.
For the case 'enable==true', validate all the function parameters
then disable the trace, update the trace settings and re-enable
the trace.
Modify the caller armv7m_trace_tpiu_config() to initialize the
variable 'prescaler' to a safe value to avoid the issue targeted
by [1].

OpenOCD is based on a single main loop that schedules all the
activities.
At the execution of a TCL command, the timestamp is checked to
eventually trigger the polling of the targets. This means that by
executing a TCL command the polling can be triggered and detect a
change of target's state.
When openocd 'resumes' a target, the target can halt again by
hitting a breakpoint.
The 'resumed' event handler is started just after the target has
been resumed, but it triggers a polling before the execution of
its very first instruction.
If the polling finds the target halted, it will run the 'halted'
event handler, that will then be executed 'before' the pending
'resumed' handler.
In case of gdb, a 'continue' command will restart the target but,
polling (and halt detection) executed before the end of the resume
process will hide the halt. As a consequence, the gdb will not be
informed of the halt and will remains waiting as if the target is
still running without showing the prompt.
This can be verified by running on the target a firmware with a
loop, run openocd with a dummy 'resumed' event, and let gdb to set
a breakpoint in the loop. A 'continue' command will cause the
target to halt again by hitting the breakpoint at the next loop
iteration, but gdb will loose it and will not return the prompt.
openocd -f board/st_nucleo_f4.cfg -c \
'stm32f4x.cpu configure -event resumed {echo hello}'
arm-none-eabi-gdb -ex 'target remote :3333' -ex 'b *$pc' -ex c
Disable the polling while executing target's resume().
Document it and provide hints to developers to cope with future
implementation.

The macro AC_HEADER_TIME helps to detect such odd case.
Nowadays all the systems properly protect 'time.h', so its safe to

The case of systems without 'sys/time.h' is already covered by

arm_le_to_h_u32() in the jtag callback.
This causes a mismatch on big-endian host and the registers get
read with the incorrect endianness.
Use an intermediate buffer to read the registers as uint32_t and
to track the destination reg.value pointer, then copy the value in
reg.value after the call to jtag_execute_queue().
Tested with qemu-armeb and an OpenOCD built through buildroot
configured for cortex-a7 big-endian.
Note that if jtag_execute_queue() fails, the openocd register
cache is not updated, so the already modified flags 'valid' and
'dirty' are incorrect. This part should be moved after the call to
jtag_execute_queue() too.

Commit fc2abe63fd ("armv7m: use generic arm::core_mode") adds
two special modes for ARMv6M and ARMv7M in struct arm_mode_data[].
While these modes do not have any additional register to be dumped
by command 'arm reg', the command still prints an header for these
modes but not followed by any register.
Detect the special modes for ARMv6M and ARMv7M and skip them to
avoid printing the useless header.

Commit fed7131049 ("armv4_5: support weirdo ARMv6 secure monitor
mode") introduces the secure mode 28 of ARMv6 as a synonymous of
mode 22 (MON), but does not add it in the switch/case in command
'arm reg'.
When command 'arm reg' scans the array arm_mode_data[] on targets
without secure modes, it does not detect the new secure mode as
not supported by the architecture, thus triggers a segmentation
fault when it try to read the register's value from unallocated
memory.
Issue detected with target arm926ejs.
Add the new mode in the switch/case and treat it as the mode MON.

Real Time Transfer (RTT) is an interface specified by SEGGER based on
basic memory reads and writes to transfer data bidirectionally between
target and host.
Every target that supports so called "background memory access", which
means that the target memory can be accessed by the debugger while the
target is running, can be used.
RTT is especially of interest for targets which do not support Serial
Wire Output (SWO) (e.g. ARM Cortex-M0) or where using semihosting is
not possible (e.g. real-time applications) [1].
The data transfer is organized in channels where each channel consists
of an up- and/or down-channel. See [2] for more details.
Channels are exposed via TCP connections. One or more RTT server can be
assigned to each channel to make them accessible to an unlimited number
of TCP connections.
The current implementation does not respect buffer flags which are used
to determine what happens when writing to a full buffer.
Note that the implementation is designed in a way that the RTT
operations can be directly performed by an adapter (e.g. J-Link).

Reading of DPIDR is the very first operation after JTAG to SWD sequence.
Without this change if DPIDR read fails then swd connect fails.
Keep trying JTAG to SWD sequence and DPIDR read until success
or timeout 0.5 sec. It makes setting of adapter srst delay on SWD transport
mostly unnecessary.
Also test for ERROR_WAIT (which should not occur according to
IHI 0031E B4.3.2 but a quirk is known) and if bus is kept stalled
then issue abort to make the next connect possible.

If dap_dp_read_atomic() in 30 trials loop fails, dap->do_reconnect is set.
Following dap_dp_read_atomic() calls dap_queue_dp_read() which in case
of SWD transport calls swd_queue_dp_read(). It starts
with swd_check_reconnect() and it calls swd_connect() because
dap->do_reconnect is set. swd_connect() does some initialization,
reads DPIDR and calls dap_dp_init() again!
Moreover if dap_dp_init() is called from cortex_m_reset_(de)assert()
one level of recursion is necessary to reconnect the target.
Introduce dap_dp_init_or_reconnect() for use in cortex_m reset
and similar.
Remove loop of 30 atomic reads of DP_STAT to prevent unwanted recursion.

Every debug log of OpenOCD contains approximately 130 lines like:
Debug: 264 147 command.c:354 register_command_handler(): registering 'flash'...
Because only root name of the command is logged, most of lines is not
too informative. E.g. registering 'flash' is repeated 14 times.
Karl Passon submitted the patch [1] changing the logged cmd name from
root to lowest level. It makes the log better. Unfortunately we also have
'reset_config' and 'cortex_m reset_config' and similar which looks
equal in the log after [1].
Moreover [1] has not been reviewed for 5 years.
So my guess is that nobody uses that crap in debug log.
Save more than 10 kbytes in any debug log and make log analyse easier
by blocking log command in #if 0 block.
If some developer eventually needs to debug cmd registering he can easily
enable logging again.
