Bug of Regular Express matching Report For Preprocessing LLVM IR

[Marvinmw]

construct_struct_types_dictionary_for_file in inst2vec_preprocess.py cannot not handle the value in to_process, { i64, { i32, { x86_fp80 } }*, [7 x { i32, { x86_fp80 } }] }.
I try to fix it but the matching seems to complex? Could you help me?

Well, it might have to do with the type x86_fp80. I do not think this was supported in LLVM 6.0, which we wrote the parser for. Perhaps a specific corner case is necessary?
