unhandled function attribute enum value: FunctionAttributeKind 26 #16
Description
Hi,
I'm trying to run Sys from the Docker image on a large code base I built using wllvm, but I'm getting this error when I run any of the checkers:
unhandled function attribute enum value: FunctionAttributeKind 26
CallStack (from HasCallStack):
error, called at src/LLVM/Internal/Attribute.hs:210:17 in llvm-hs-9.0.1-GdcY7lIsVQ6GWzw7sPUMKI:LLVM.Internal.Attribute
Not sure if this is a result of something I'm doing wrong or if llvm-hs is the problem. Any help would be greatly appreciated.
Thanks!

Nope, this is not on you. This is an llvm-hs problem. I hinted on how to go about this here #15 (comment). Happy to update llvm-hs dependency if you end up fixing the issue. If it's too much of a pain: if you can give me a .bc/.ll file I can take on both of these issues soon-ish

Having some trouble building llvm-hs from source but I'll keep trying some things. In the mean time here's a .bc file that's causing the error. Thanks again!

I got this fixed! It's the same problem as in this issue where llvm-hs doesn't support the NoFree attribute. The commit that fixed this hasn't been incorporated into latest version of llvm-hs in Hackage, so you have to build it from source

Sure thing! To build llvm-hs from source in the Docker image, I first cloned the llvm-hs repo into the image. Then, in the stack.yml file in Sys, I did two things:
You can look at my fork of Sys to see how I did it. After that, you should be able to call

@Gavazzi1 @deian Hello! I am facing this issue while parsing a .ll file generated using gllvm, and I want to build llvm-hs from source, are there any steps for this using Cabal ? My project isn't a big project so it doesn't have a project file, I've done all the installation manually. I have cloned the llvm-hs repo, checked out to the llvm-9 branch (which has this fix - llvm-hs/llvm-hs#284) but not sure what to do after this, if someone could help me with the steps, it would be great
