This only fixes the comparisons
if (symbol == NULL)
if (symbol != NULL)
The case of NULL on the left side of the comparison is not tested.
Some automatic fix is incorrect and has been massaged by hands:
- if (*psig == NULL)

* configure: drop macro 'AC_HEADER_TIME'
The macro AC_HEADER_TIME has been obsoleted by autoconf 2.70.
Not all systems provide 'sys/time.h', plus some old system didn't
allowed to include both 'time.h' and 'sys/time.h' because 'time.h'
was included by 'sys/time.h' and was not properly protected to
allow multiple inclusion.
The macro AC_HEADER_TIME helps to detect such odd case.
Nowadays all the systems properly protect 'time.h', so its safe to
unconditionally include 'time.h', even if it is also included by
'sys/time.h'.
The case of systems without 'sys/time.h' is already covered by
configure.ac through the directive
AC_CHECK_HEADERS([sys/time.h])
Remove the obsoleted autoconf macro and simplify the code by
including 'time.h' unconditionally and check HAVE_SYS_TIME_H to
include 'sys/time.h'.

changes which I didn't want to include here.
Built like this, OpenOCD passes:
* All single-RV32 tests against spike.
* All single-RV64 tests against spike.
* Enough HiFive1 tests. (I suspect the failures are due to the test
suite rotting.)
* Many dual-RV32 (-rtos hwthread) against spike.
* Many dual-RV64 (-rtos hwthread) against spike.
I suspect this is an overall improvement compared to what's in mainline
right now, and it gets me a lot closer to getting all the riscv-openocd
work upstreamed.

* riscv: work around buggy hart states during reset in some DMs
As described in the comment this change adds, the GD32VF103 DM reports
that the hart is in more than one state while it is resetting. Because
of this, the current code acknowledges resets before they actually
complete. This sometimes prevents havereset from getting cleared as
intended, leading to a spurious "Hart 0 unexpectedly reset!" message the
next time riscv_is_halted() gets called.
To work around this, check for the absence of the unavailable state
rather than the presence of the running or halted states. This behavior
is also arguably more true to the spec than what exists now: Section 3.2
states that "The system may take an arbitrarily long time to come out of
reset, as reported by allunavail, anyunavail."

The reset-assert event is used, if present, to override the default

nonstandard reset sequences can specify the appropriate logic in Tcl.

The GD32VF103 is a low-cost 32-bit RISC-V microcontroller with
peripherals that are more-or-less compatible with the STM32F103 ARM
microcontroller. It is available on several low-cost dev boards, such as
the Sipeed Longan Nano, which is what I am testing on.
Add initial support for this chip, including a workaround for a buggy
ndmreset line (i.e. one that doesn't actually trigger a reset) in its
integrated debug module. Use the existing GD32VF103 flash driver that
was ported from the vendor's code in commit 48e40f3513 ("Add support
for GD32VF103 flash").

* tcl/target/gd32vf103: add main flash alias
The GD32VF103 creates an alias to either main flash or the bootloader at
0x0, depending on how it was booted. As such, we want to indicate to
debuggers that the memory at 0x0 is flash and so cannot support software
breakpoints. To do this, add an alias to the main flash in the config.
This isn't strictly accurate in the case where we're running the
bootloader, but it still suits our purpose of fixing breakpoint
behavior.

Command "riscv set_prefer_sba" is left and works in backward
compatible way, but is marked as deprecated.
First time abstract memory access is executed, it is tried with
set aampostincrement bit. If the abstract command fails or the
address is not incremented correctly, aampostincrement will not
be used for any subsequent accesses.

In a switch/case statement, a break placed after a goto or return
is never executed.
The script checkpatch available in Linux kernel v5.1 issues a
warning for such unused break statements.
In the process of reviewing the new checkpatch for its inclusion
in OpenOCD, let's get rid of these warnings.
The script checkpatch is unable to fixup automatically this case.
Thanks to having "break" command using a single code line, this
patch has been generated using the script below:
find src/ -type f -exec ./tools/scripts/checkpatch.pl -q \
--types UNNECESSARY_BREAK -f {} \; \
| sed -n '/^#/{s/^.*FILE: //;s/:$//;s/:/ /;p}' \
| awk 'function P() {print "sed -i '\''"b"'\'' "a};
{
if ($1!=a) {
if (a) {P()};
a=$1;
b=$2"{d}";
} else {
b=b";"$2"{d}"
}
};
END {P()}'

The script checkpatch available in new Linux kernel offers an
experimental feature for automatically fix the code in place.
While still experimental, the feature works quite well for simple
fixes, like spacing.
This patch has been created automatically with the script under
review for inclusion in OpenOCD, using the command
find src/ -type f -exec ./tools/scripts/checkpatch.pl \
-q --types POINTER_LOCATION --fix-inplace -f {} \;
then manually reviewed.
OpenOCD coding style does not mention the space around pointer's
asterisk, so no check is enforced. This patch only makes the style
uniform across the files.
The patch only changes amount and position of whitespace, thus
the following commands show empty diff
git diff -w
git log -w -p
git log -w --stat

* Handle DMI busy in sba write.
If we encounter DMI busy on the NOP after a read, we'll never get the
value out because DMI busy is sticky. The read must be retried, but we
don't know whether it was ever issued. Since the read has side effects
(incrementing of the address) this retry must be handled at a higher
layer. So now dmi_op_timeout can be told to retry or not, and if retry
is disabled it'll return an error when busy.
Also actually properly do the retry in dmi_op_timeout(). Previously the
code would not reissue the command and end up returning a garbage value.

The original OpenOCD code issued FENCE & FENCE.i twice for the current
hart (which is harmless, but takes time).
Avoiding this extra FENCE is a slight performance improvement. Per my rough
measurements, this improves performance of certain debugger actions
(single-stepping) by approx. 20% in single-hart systems.
Abstract write size (aarsize) to shall always match the real

* Adds support for RISCV Access Memory Abstract Commands
The Access Memory Abstract Command is one of the three optional
methods for reading and writing memory on a complient RISCV

in OpenOCD.
Implementation Notes:
- aamvirtual is hard-coded to false until the design for accessing
virtual addresses is finalized.
- aamsizes corresponding to 8b, 16b, 32b, and 64b are supported.
128b support is postponed until it is required, as it will mean
changes to the read/write_abstract_arg() interface to pass 128b
values.
- aampostincrement is not used and hard-coded to false.
* Changes from review.
* Additional lint fixes and a typo from last commit.
* Fixing a clang error.

* Use "algorithm" to compute CRC on RISC-V targets.
Use the C compiler to generate the algorithm code. It's better at
assembly than I am. We need separate RV32 and RV64 binaries to handle
shift instructions. I used the code from gdb (libiberty really) because
it returns the correct result. I'm not sure if the table is worth it
since we do have to save/download/restore more bytes now.
riscv_run_algorithm() now properly saves and reads back all registers
used for parameters. It also doesn't check final_pc if exit_point is 0.
Using gdb means I don't know the exact address where the code will end.

Currently the RISC-V compliance test suite doesn't output the test is

many tests. This makes it very hard to find out which test fails.

being executed before it actually runs, and by adding the source code
line where the test is located, making it easier to look up the test in

This improves startup time, which is important when connecting to
simulators. One problem is that triggers that are set when the debugger
connects are not cleared until enumeration happens. Execution may halt
due to a trigger set by a previous debug session, which could confuse
the user. If this happens, triggers will be instantly enumerated, so it
will only happen once per session.

This saves us from re-reading s0 before doing just about anything
program buffer related.
Improves DebugBreakpoint from 3.01s to 2.89s. Feels like the improvement
should be larger than that. Maybe my metric isn't very good.

This works around some side effects of the -rtos hack, namely that we
were unable to set hardware breakpoints on harts whose misa differed
from the first one. There may be other bugs like this one lurking
elsewhere. The only proper solution is for gdb to have a better user
interface when talking to a server that exposes multiple targets, but
that's a very big project.
This fixes#194.

If the target is held in reset we'd keep adding more delays, and since
those grow exponentially they'd get so huge it would take forever to
exit out of the loop.

This allows a user to tell OpenOCD to prefer system bus access for
memory access, which can be useful for testing, or when there really is
a difference in behavior.

This code was submitted at
https://github.com/riscv/riscv-openocd/pull/214. This change
incorporates that code, makes it build, and fixes the style to fit the
OpenOCD style guide.
I have not tested the new code because I don't have a target. It does
not cause any regressions.
Change-Id: Ic3639d822c887bd4a5517f044855fdd9d4e5a46d
Mostly addresses #207.
Also changed dmi_read() to return an error, and fixed all the call sites
to propagate that error if possible.

Instead of asserting, return error when an abstract register access
fails on running target.
Fixes#201

It confuses users of IDEs like Eclipse, which request to read registers
that don't exist on the target.
Fixes#176

When authdata_write sets the authenticated bit, examine() every OpenOCD
target that is connected to the DM that we were authenticated to.

They can be used to authenticate to a Debug Module.
There's a bit of a chicken and egg problem here, because the RISCV
commands aren't available until the target is initialized, but
initialization involves examine(), which can't interact with the target
until authentication has happened. So to use this you run `init`, which
will print out an error, and then run the `riscv authdata_read` and
`riscv authdata_write` commands. When authdata_write() notices that the
authenticated bit went high, it will call examine() again.
Example usage (very simple challenge-response protocol):
```
init
set challenge [ocd_riscv authdata_read]
riscv authdata_write [expr $challenge + 1]
reset halt
```

... by disabling all triggers, single stepping, enabling them, and then
resuming as usual. Without this change, you'd just be stuck on an
address trigger and would have to manually disable it.

Fixed abstract register access for registers that aren't XLEN wide.
Avoided excessive errors cases where we attempted to execute a fence but
failed.
Don't mark all the CSRs as caller-save. gdb was saving/restoring
dscratch, which broke function calls as a side effect. dscratch is
accessible for people who really know what they're doing, but gdb should
never quietly access it. The same is probably true for other CSRs.

It's not tested because spike never reports any busy errors since every
access happens instantaneously.

As part of this I improved the memory read/write fatal error handling a
bit. Now at least we try to leave autoexec turned off, and will even
restore the temp registers if the situation isn't too hosed for that.
Partly addresses Issue #142

Because there is no instruction that moves just half of a 64-bit FPR
to/from a GPR, we need to use scratch memory for this operation. This
code can theoretically use:
1. DMI_DATA, if it is memory mapped in the target.
2. DMI_PROGBUF, if it is writable in the target.
3. A user-configured address.
I have only tested this code very lightly. One reason is that gdb thinks
that on RV32 harts every register is 32 bits wide. Another is that this
is mostly proof-of-concept to satisfy the small program buffer code
review, which I don't want to drag out forever.
Existing tests don't realize that floating support was broken with
RV32D, and don't realize that it still doesn't work because of the gdb
problem mentioned above.
This change improves Issue #110 but there's more work to be done.
