This is xnor(N, V) & !Z, and since as you now know xnor = eqv, you can perform
this in just two steps.

!A & !B -> !(A | B), so one fewer xor.

Likewise.

Surely you'd put all of this size+sign-extend mapping into a table and issue
just one tcg_gen_qemu_st_tl.

And re-use the same table here, it would appear.

Huh? A missing TODO, perhaps?

Race condition. What is a global variable doing being set by a translation thread?

Wow, this looks wrong.
It doesn't work with icount or single-stepping. You need to be able to begin a
TB at any instruction, including a delay slot.
You should have a look at some of the other targets that handle this, e.g.
openrisc or sparc. Since you've got NPC already, for looping, sparc is
probably the better match.
There should be no reason why you'd need to emit insn_start outside of
arc_tr_insn_start.

Lots of changes to status imply a significant change to processor state, and so
you need to exit to the main loop.

Wow, really? Can't you grab this directly from the operand decoding? Where
surely we have already ensured that the relevant regnos are not odd.

The g_assert_not reached should have been sufficient.

Riiiight. Auto-generated code, clearly.
What program generated this, and from what source? As it stands this is
unmaintainable. I'm going to stop reviewing now.

We are also able to start TB at any instruction, that is not what is
being validated here. It is just verifying if a delayslot instruction
does not have the delayslot flag set, and that the delayslot instruction
does not have a limm.
The way we encode delayslot instructions is a little peculiar. When some
instruction defines a delayslot, it calls this function and the
instruction is decoded inline.
As far as I remember the change of instruction context, with
tcg_gen_insns_start, allowed us to properly make gdb jump from branch
instruction to delay slot instruction and then back.
The asser was used to guarantee that those conditions where never broken
internally. The condition becomes irrelevant.

Indeed, we can grab it from operand decoding. Please allow us to do this
change once we rework binutils code.
Hi Richard,
Thank you so much for your reviews.
I will start working on improving the code straight away to try to
minimize waiting times.
However lets just address the elephant in the room.
Indeed we have the TCG definitions being generated.
However we are very serious about wanting to upstream our port and we
will certainly maintain this code.
I totally understand your concerns with generated code.
To explain our decision, we have an internal database that we are able
to describe the architecture and map encoding with hw semantics, and
for the sake of saving us debug time generating each and every
instruction, we use it to generate both the TCG and instruction
decoding tables that you have already reviewed.
This tool is not only used in QEmu but through all our tools code,
allowing us to cross validate the content of the database.
Considering our situation and current state of the port, what would
you think is a reasonable compromise?
Once again thanks for the reviews.
Best regards,
Cupertino

In some respects you're in the same situation as the hexagon target that's currently in flight on the list -- both of you are wanting to generate tcg from a company-specific canonical source. In the case of hexagon, the target/hexagon/imported/ subdirectory contains a bunch of stuff exported from Qualcomm's specification. It's not fantastically readable, but it's not bad. These files are then massaged in various ways to produce either (1) out-of-line helpers or (2) inline tcg stuff. Without knowing what form the Synopsys database takes, how easy would it be to export something mostly human-readable, which could then be processed by a tool that is included in the qemu source? Future qemu maintainence is thus on the tool, and not on the auto-generated code. There's also clear separation on what needs tcg review and what's simply a spec update. r~
Hi Richard, Thanks for your quick reply, and again, thanks for the reviews. We have already started to make very significant changes to the port based on your comments. ;-) Our generation tool has different levels of verbosity, expressing instruction semantics from a pattern level up to what it is shown in <semfunc.c> as comments, which is later converted to TCG format. For QEMU purposes I would say that input format should be what is shown as comments in <semfunc.c> file. I believe that I can in relative short time isolate the TCG generator and prepare a tool to process those comments and update the respective TCG definitions. Also, as is, the generator is done in Ruby, and to be honest, would not be very easy to redo in some other language. Would this be considered a problem if we would include it as Ruby code ? IMO execution of these scripts should not be a step of build process but rather a development one, such that Ruby does not become a requirement to build QEmu.

It's not ideal -- I would have preferred python or C -- but I won't object. At minimum, I would expect build system changes that detects ruby support in the system, and a manual build rule that rebuilds the generated files. This build + check-in process would want documenting in target/arc/README or something. If there are any ruby packages required apart from the base language, this should be documented as well (I know nothing about ruby myself, just guessing based on what happens with python and perl). Even better would be build system changes that, if ruby is installed runs the generator, and only fall-back to the checked-in files if ruby is missing. In this way, anyone who wants to modify the code generator would merely have to install the ruby packages on their system, but they would not be required for a non-ARC developer to build. r~
Seems perfectly doable, no objections. It will probably take me longer to integrate it in the build system then to get the scripts ready. I will start by placing the ruby tool and documentation there, and later on, integrate it in the build system. Hope that you get re-motivated to review our patches. No pressure though ;-) Very valuable comments, lots of improvements happening here.
