Hi Maleadt,

I have the same problem when testing CUDA

```julia
 Testing Running tests...
ERROR: LoadError: LoadError: UndefVarError: parameters not defined
Stacktrace:
  [1] call!(builder::LLVM.Builder, rt::GPUCompiler.Runtime.RuntimeMethodInstance, args::Vector{LLVM.ConstantExpr})
    @ GPUCompiler ~/.julia/packages/GPUCompiler/XwWPj/src/rtlib.jl:57

```

I have still updated both packages

```julia

(@v1.6) pkg> update LLVM
    Updating registry at `~/.julia/registries/General`
  No Changes to `~/.julia/environments/v1.6/Project.toml`
  No Changes to `~/.julia/environments/v1.6/Manifest.toml`

(@v1.6) pkg> update ExprTools
    Updating registry at `~/.julia/registries/General`
  No Changes to `~/.julia/environments/v1.6/Project.toml`
  No Changes to `~/.julia/environments/v1.6/Manifest.toml`

```

but this did not change anything when testing CUDA. Are there further steps neccessary?
