Add TriCore Architecture #1973

imbillow · 2023-03-10T22:14:54Z

Changes based on https://github.com/TriDis/capstone/tree/tricore, adaptations for new capstone versions and support for current versions of the TriCore instruction set.

The current tc1.6.2 version of instruction set disassembly is almost complete. Other versions actually overlap with tc1.6.2 for the most part, with only a small amount of extra content, which is still under construction.

Then it should be mentioned that basically all the .inc is generated using the modified llvm-tblgen from https://github.com/Rot127/llvm-capstone/tree/auto-sync-tblgen, except for TriCoreGenDisassemblerTables.inc, which modified a small part of DecodeInstruction and DecodeToMCInst

Very nice work! From which llvm is this, please?

Very nice work! From which llvm is this, please?

Maybe https://github.com/TriDis/llvm-tricore

aquynh · 2023-03-10T23:05:37Z

Is that unmaintained repo?

Yes, and I meant to use this as a starting point only. We could probably maintain TriCore's TableGen and TriCoreDisassembler code ourselves.

aquynh · 2023-03-10T23:25:32Z

Can we assume that this arch is no longer developed? (Unlike Arm, x86, etc)

imbillow · 2023-03-10T23:52:18Z

I think it's just not as widely used.

imbillow · 2023-03-11T08:20:21Z

ping @XVilka

XVilka · 2023-03-11T08:36:59Z

@imbillow @imbillow this arch is indeed not widely used but quite common in the automotive and few other industries. This architecture is still being improved with ISA changes slightly from version to version, latest one being 1.6.2:

https://wiki.qemu.org/Documentation/Platforms/TriCore

The aforementioned LLVM fork isn't complete and abandoned, and Infineon didn't indicate that they plan to implement Tricore support in the mainline LLVM or even some open fork. Thus, I suggest we focus only on the capstone and maintain it separately from the LLVM things.

XVilka · 2023-03-11T08:39:47Z

@imbillow note, there are slight differences for some instructions between different ISA versions, we should add the way to specify the particular ISA in the API.

XVilka · 2023-03-13T02:07:51Z

@Rot127 could you please also take a look, in case it will interfere with the auto-sync work?

Rot127 · 2023-03-13T14:38:22Z

@XVilka Looks good to me.
Only the architectures which are generated with auto-sync will be adjusted to each other. Since you mentioned that Tricore will not be in the LLVM mainline (and is therefore not a candidate for auto-sync) there's no need to adjust it to the auto-sync design.

Could you please check my messages in Rizins Mattermost? Depending what you say regarding the auto-sync compatibility, I'd like to review this as well.

imbillow · 2023-03-27T19:49:04Z

There should be special handling for different versions of ISA that hasn't been done yet. Currently, only TC1.6.2 is being referenced. Also, the testing may not be comprehensive enough, and I feel that there are still quite a few bugs present.

XVilka · 2023-04-06T04:26:09Z

@imbillow could you please also maintain a very brief TODO/status in the PR description?

done

imbillow · 2023-04-09T19:40:19Z

Now our disassembled mnemonic and op_str are pretty good, but inst_detail is not quite as good

XVilka · 2023-04-10T02:14:32Z

@kabeor could you please take a look at this to give the early feedback, since majority of the code was written, also to allow the CI jobs to run?

imbillow · 2023-04-10T17:35:32Z

Because I'm not very familiar with Python 2, so I converted the test_corpus.py file to Python 3 syntax, resulting in the new test_corpus3.py. Their functionalities should be essentially the same.

However, the cifuzz GitHub action relies on google/oss-fuzz to complete the fuzz test, so it won't use test_corpus3.py. But I think it should still be useful, so I submitted it anyway.

XVilka · 2023-04-11T13:50:21Z

@kabeor what do you think about such script conversion?

XVilka

LGTM. @aquynh @kabeor all your feedback was addressed. Your call now.

@kabeor Hi, the problem you mentioned has been fixed, please review again.

Rot127 · 2023-05-02T11:00:24Z

@kabeor @aquynh Is it ready to be merged?

kabeor · 2023-05-02T11:15:11Z

@imbillow @Rot127 It's really great, can you solve the conflict so I can merge?

XVilka · 2023-05-03T01:34:04Z

@kabeor looks like conflict was resolved 😁

kabeor · 2023-05-03T03:30:57Z

Thanks again for this great work! Merged.

XVilka · 2023-05-04T09:04:29Z

@aquynh @kabeor what do you think about tagging 5.0-rc3 with that (and release 5.0 once it's stable enough)? I wonder if it make sense to release 5.0 before auto-sync is merged, and focus 5.1 on auto-sync work?
cc @imbillow @Rot127

Maybe addressing these two first though: #2010 and #2009

aquynh · 2023-05-04T10:43:41Z

this is what i am planning to do.

anything else do you think should be merged before rc3 tag?

yes, please make pull req for the above issues before rc3 tag.

my main concern now is that the Pypi package is still properly generated for all platforms.

@aquynh Would agree with releasing v5.0 before auto-sync and v5.1 for updated ARM, PPC and whatever else is done at this point.

yes the auto-sync is a big change, so I want to release 5.0 before merging that.

You are right
