<div>
<pre>`llvm::appendToGlobalArray` (and as a result, `appendToGlobalCtors` and
`appendToGlobalDtors`)
always produce an unqualified function pointer
(c.f.
<a href="https://github.com/llvm-project/llvm/blob/master/lib/Transforms/Utils/ModuleUtils.cpp#L31">https://github.com/llvm-project/llvm/blob/master/lib/Transforms/Utils/ModuleUtils.cpp#L31</a>
),
which later leads to the verifier rejecting the generated call with "wrong type
for intrinsic global variable"
for platforms that require a separate address space for functions (e.g. AVR)
(c.f. <a href="https://github.com/llvm-project/llvm/blob/master/lib/IR/Verifier.cpp#L651">https://github.com/llvm-project/llvm/blob/master/lib/IR/Verifier.cpp#L651</a>
- checking against a function pointer in the default program address space).
I'm not sure what the process for proposing fixes in llvm is, so I decided to
submit a bug
instead of attempting to make a merge request with a fix.</pre>
