Extractvalue in global constant not supported?

[moll]

Hey,

Thanks for maintaining the LLVM IR pretty printer!

Is it me or is the ExtractValue constant not supported?

llvm-hs-pretty/src/LLVM/Pretty.hs

Line 1051 in 990bb69

instance Pretty C.Constant where

seems to err with "Non-function argument. (Malformed AST)" upon meeting one. As far as I can tell, it seems to be valid syntax. E.g:

%Age = type {i32}

@answer = private unnamed_addr constant i32 extractvalue (%Age {i32 42}, 0)

Thanks!
