Building with "-D BYTECODE_RUNTIME=llvm" builds fail with llvm >=14

Describe the bug

Trying to build clamav 0.104.3 on Fedora rawhide. Get:

[ragusaa]

Thank you for the report. I am working on reproducing the problem now, will let you know when I have something.

[ragusaa]

AllocateRWX and ReleaseRWX have been replaced by allocateMappedMemory and releaseMappedMemory. It appears that there are other changes that have been made as well. I do not know at this time when upgrading our code to work with llvm 14 will be scheduled. I will keep you updated.

[opoplawski]

Indeed, it looks like clamav doesn't support llvm > 3.6.2.

[ragusaa]

I have tested llvm 8 - 12 with clam. Are you having issues building with those versions?

EDITED: you are correct, llvm works on 0.105.

[opoplawski]

Thanks, we'll try again when we shift to 0.105 - which will probably be a while due to the shift to rust.

[Kangie]

@ragusaa Any update on the scheduling for this one? Gentoo has recently moved to the point that the only available versions of LLVM from the default repositories are >=14

[ragusaa]

Unfortunately, I don't have an update on when this will be scheduled.

[Kangie]

I just wanted to ping on this one again; it's been a few months and we're now looking at LLVM 14-16 marked stable for most arches in Gentoo, with 17 on the way. I'm quite interested in enabling our users to optionally set BYTECODE_RUNTIME=llvm to take advantage of the feature at some point.

It looks like clamav is gearing up for 1.2.0 (yay) but a quick test on main seems to indicate that it's still broken; I guess this will be at least 1.3.0 away!

Please consider this an 'I'm very interested' rather than another request for a scheduling update 😄

Edit: Can we update the issue title, too? Something more descriptive like "-DBYTECODE_RUNTIME=llvm builds fail with llvm >=14"; I always forget which issue this is when I check back for updates, and everything else works fine with every version of LLVM I've tested!

[micahsnyder]

We're presently working on updating the LLVM support in the bytecode compiler and plan to address LLVM runtime support after that. But you're right, it won't make 1.2.0.
