Wait for fixed time before accessing AP. Not nice, but the only

Commit 236c54c94a ("server/gdb_server.c: support unavailable
registers") correctly returns a string of 'x' when the register is
not available in the current target.
While implementing this, it incorrectly drops the pre-existing
feature of optionally ignoring errors while reading a register.
This feature has a real use case documented in the OpenOCD manual
in chapter 'Using GDB as a non-intrusive memory inspector', where
GDB attaches to a target without halting it. For targets that need
to be halted to read its registers, we need to hack the values of
the registers returned to GDB; either returning 'xxxx' or an error
causes GDB to drop the connection.
Re-add the check on 'gdb_report_register_access_error' to keep the
pre-existing behavior when a register error has to be ignored:
- return a string of '0';
- drop a debug message.

clang doesn't support the gnu_printf attribute that OpenOCD uses if

Most clang builds set __GNUC__/__GNUC_MINOR__ to 4.2 for historical
reasons, so they don't trigger this condition; however, some builds set
it to something much higher to work around code using __GNUC__ to
determine if a feature that does exist in clang (but not gcc 4.2) is

The problem can be reproduced without a special clang build by adding

The initial OpenOCD code for Cortex-A (ARMv7a) [1] was merged in
2009 but, due to lack of public documentation for ARMv7a, it was
almost a simple copy/paste from the existing code for Cortex-M
(ARMv7m).
On Cortex-M the same AP provides access to both CPU debug and CPU
memory. This feature is not present on ARMv7a.
To still keep some communality with ARMv7m code, the change [2]
splits the CPU debug access from the CPU memory access by using
two independent AP; this is copied from the system architecture of
TI OMAP3530 which provides to DAP a direct AHB-AP memory bus on
AP#0, separated from AP#1 for the APB-AP CPU debug.
But the direct memory access through the system bus breaks the
coherency between memory and CPU caches, so change [3] added some
cache invalidation to avoid issues.
The code to allow ARMv7a CPU to really read/write in CPU memory
was added by change [4] in 2011. Such still not optimized
implementation was very slow, so it did not replace the access
through the system bus. A selection through DAP's 'apsel" command
was used to select between the two modes.
Only in 2015, with change [5], the speed of CPU read/write was
improved using the DCC_FAST_MODE. But the direct access to the
memory through the system bus remained.
Finally, with change [6] in 2018 the system bus access was dropped
for good, as the new virtual target "mem_ap" could implement such
access in a more clean way.
Only memory access through CPU remained for ARMv7a.
Nevertheless, a useless cache invalidation remained in the code,
decreasing the speed of the write access.
Drop the useless cache invalidate on CPU memory write and the
associated comment, not anymore valid.
Drop the now unused function armv7a_cache_auto_flush_on_write().
This provides a speedup of between 4 and 8, depending on adapter
and JTAG/SWD speed.

The gdb subsystem is initialized after the first target examine,
so the field struct target::gdb_service is NULL during examine.
A command "smp off" in the examine event handler causes a SIGSEGV
during OpenOCD startup.
Check for pointer not NULL before dereferencing it.

The code for cortex_a allocates the register cache during the very
first examine of the target.
To prevent a segmentation fault in assert_reset(), the call to
register_cache_invalidate() is guarded by target_was_examined().
But for targets with -defer-examine, the target is set as not
examined in handle_target_reset() just before entering in
assert_reset().
This causes registers to not be invalidated while reset a target
examined but with -defer-examine.
Change the condition and invalidate the register cache if it has
been already allocated.

Commit 16b4b8cf54 ("Cortex-M3: expose most DWT registers") added
the DWT registers to the list of CPU registers.
The commit message from 2009 reports the reason behind this odd
mixing of CPU and DWT registers.
This feature got broken in 2017 with the introduction of the field
struct reg::exist and its further use in the code. As result, the
command 'reg' on a target Cortex-M reports only the core registers
and then the header line
===== Cortex-M DWT registers
not anymore followed by the DWT registers.
Fix it by tagging each DWT registers as existing.

It was noticed that the remote_bitbang protocol has a design issue:
SWD and sleep commands cannot be implemented at the same time, because
they overlap:
- SWD uses d,e,f,g for setting pin state
- sleep uses d,D for microsecond and millisecond sleep, respectively
This has previously been reported by Marek Vrbka, but it wasn't fixed.
This commit does the following to resolve the issue:
- Change the sleep commands to 'Z' for 1 ms, 'z' for 1 µs
- Document 'D' and 'd' as deprecated aliases
- Switch the remote_bitbang driver in OpenOCD to 'Z' and 'z'
Unfortunately that's a breaking change, because existing adapter-side
implementations of the protocol will have to implement the new commands
to keep working with future versions of OpenOCD. Fortunately, the
remote sleep commands haven't been part of an OpenOCD release yet,
which should limit the breakage somewhat.

Commit 290eac04b9 ("drivers/linuxgpiod: Migrate to adapter gpio
commands") introduced an incorrect check to determine if the
library libgpiod declares the line request flags:
GPIOD_LINE_REQUEST_FLAG_BIAS_DISABLE
GPIOD_LINE_REQUEST_FLAG_BIAS_PULL_UP
GPIOD_LINE_REQUEST_FLAG_BIAS_PULL_DOWN
The names above are declared by the library inside an enum, thus
cannot be used by the C preprocessor in a #ifdef.
Determine in configure if the version of libgpiod provides the
line request flags for "bias" and define a C macro.
Use the new macro in the driver code.
