It would be great to add the missing abondon() function here, because otherwise I cannot use the allocation for fixups (in case of errors, I need to free the memory). The context is easier to understand on the individual commit https://github.com/llvm/llvm-project/pull/169482/commits/f1203f207722a9d95c5dd73b6724308a5ef81f5d
