d7558e2ed6 target/armv7m: fix static analyzer warning
Despite of assert(is_packed) clang static analyser complains on use
of the uninitialized offset variable.

Cross compiling with latest x86_64-w64-mingw32-gcc hits warnings
	src/target/armv7m.c: In function ‘armv7m_read_core_reg’:
	src/target/armv7m.c:337:54: error: ‘reg32_id’ may be used
	    uninitialized in this function [-Werror=maybe-uninitialized]

It happens because mingw32 defines assert() without the attribute
"noreturn", whatever NDEBUG is defined or not.

Replace assert(is_packed) by if (is_packed) conditional and call
assert(false) in the else branch.

bbbfddc3ef jimtcl: restrict memory leak workaround on Linux only
The workaround for jimtcl 0.80 in commit 36ae487ed0 ("jimtcl:
add temporary workaround for memory leak in jimtcl 0.80") issues a
compile time error on macOS:
	../src/helper/command.c:157:22: error: aliases are not
	supported on darwin
	__attribute__((weak, alias("workaround_createcommand")));
The OS is x86_64-apple-darwin19.6.0 and the compiler used is
x86_64-apple-darwin13.4.0-clang.

Restrict the workaround on Linux host only. The fix for 'expr'
syntax change is already merged and the workaround will be dropped
soon.

77b28ced14 rtos: Add support for Zephyr RTOS
With this patch, the Zephyr[1] RTOS is supported by OpenOCD.

As usual with support for other RTOSes, Zephyr must be compiled with
the DEBUG_THREAD_INFO option. This will generate some symbols
with information needed in order to build the list of threads.

The current implementation is limited to Zephyr running on ARM
Cortex-M processors. This is the only ARM variant supported by Zephyr
at the moment and is used on most of the officially supported boards.

transport to/from the FPGA. The different UIs use TCP/IP
as transport. The JtagHost makes the bridge between these

Create a TCL procedure to be called by telnet auto-complete code

same command and will filter-out the unwanted command names.

Initialize the list of commands to be filtered-out with the name
of the TCL procedure above, as it is considered as internal.

b60d06ae32 tcl/board: add pico-debug support
pico-debug is not a board; it is a virtual CMSIS-DAP adapter that
runs on the same RP2040 also being debugged.  This is possible due
to pico-debug running on the normally-dormant second Cortex-M0+
core (Core1), providing debugging of the first core (Core0).
As such, it could be used on a variety of RP2040-based boards.

Since a flash driver is useful (if not essential), a flash driver
is included.  This driver code originated on RPi's bespoke OpenOCD
fork; lipstick was added to this particular pig to make it more
presentable on OpenOCD proper.

no new Clang analyzer warnings

64a3e7ba4f flash/nor/stm32f1x: Add support for GD32F1x0/3x0
Nowadays, when it's difficult to buy STM32F030,
the use of GD32F130 seems to be an interesting functional alternative.
This is cortex-M3 and it works with the stm32f1x driver, but unfortunately not fully.
The main difference is another offset of user option bits
(like WDG_SW, nRST_STOP, nRST_STDBY) in option byte register
(FLASH_OBR/FMC_OBSTAT 0x4002201C).
Any use of functions like lock or unlock results in change default values of the those bits stored in flash.
Thus broken microcontroller is malfunctioning, e.g. flash block programming is interrupted
by unexpected active hardware watchog (after 0.4s).
This patch is a simplified version of #4592 done by Dominik Peklo (http://openocd.zylin.com/#/c/4592/).
GigaDevice GD32F1x0 & GD32F3x0 series devices share DEV_ID
with STM32F101/2/3 medium-density line,
however they use a REV_ID different from any STM32 device,
so can be succesfully detected.

87c90393fe Cleanup of config/includes.
Remove a use of AH_BOTTOM from configure.ac. This macro is used by
autoheader to add '#include' of some include file to the end of
config.h.in and then to config.h. OpenOCD can be built with a custom
config.h, so it's preferable to move these '#include' statement directly
in the C files that need them dropping this unneeded dependency.

It also causes problems when I want to use the gnulib library (which
comes with its own Makefile, and does not have the same include path as
the top-level Makefile).

So this change touches a lot of files, but is actually really simple. It
does not affect functionality at all.

b44948985f drivers/ftdi: drscan: Skip DR-PAUSE when endstate == IDLE
Currently, all drscan commands will cycle through DR-PAUSE before reaching
TAP-IDLE. This patch provides a different path on FTDI driver.

This change is required for the ST On Chip Emulator (OnCE), to avoid
re-enabling the OnCE tap after every DRSCAN. This is because the OnCE
TAP (see ST Application Note AN4035) gets disabled if DR-PAUSE is entered
before DR-UPDATE.

With this commit, the current path:

DR-SHIFT -> DR-EXIT1 -> DR-PAUSE -> DR-EXIT2 -> DR-UPDATE -> IDLE

is changed to:

DR-SHIFT -> DR-EXIT1 -> DR-UPDATE -> IDLE

only if IDLE is the endstate (which is the driver default).

Before this patch, once the SHIFT sequence is complete, the driver would
normally move to the nearest stable state, which is DR-PAUSE, by clocking
out a '10' binary sequence. Then it would follow the path provided by
tap_get_tms_path() to reach endstate. It is done this way because
tap_get_tms_path() only supports stable states.

After this patch, the strategy is mostly the same, with the exception that,
if TAP_IDLE is the endstate, a '110' binary sequence is output after completing
the SHIFT sequence. This takes the TAP directly to IDLE, with no further action
required.

A scheme of the DR chain is shown below. A * character is used to mark the
stable states.
