To deal with that, we need to modify [MKElaborateFunc] to check one instruction at a time, which looks easy enough until you remember some of these instructions (namely, [Block], [Loop] and [If]) actually takes instructions as their arguments. This is why we add to [MKElaborateFunc] a queue of lazy iterators ([LazyVec]), itself traverse with a lazy iterator ([LazyVec]). As a consequence, the [MKElaborateFunc] ticks are divided even further, and the size of each bound should be bounded. --- src/lib_scoru_wasm/binary_parser_encodings.ml | 26 ++++- .../test/test_parser_encoding.ml | 26 ++++- src/lib_webassembly/binary/decode.ml | 100 +++++++++++++++--- src/lib_webassembly/binary/decode.mli | 6 +- .../test/integration/test_sc_rollup_wasm.ml | 2 +- 5 files changed, 135 insertions(+), 25 deletions(-) diff --git a/src/lib_scoru_wasm/binary_parser_encodings.ml b/src/lib_scoru_wasm/binary_parser_encodings.ml index 4fb10e5ced35..000a614712c0 100644 --- a/src/lib_scoru_wasm/binary_parser_encodings.ml +++ b/src/lib_scoru_wasm/binary_parser_encodings.ml @@ -1117,17 +1117,33 @@ module Module = struct let func_kont = scope ["func_kont"] (Lazy_vec.encoding Code.func_encoding) in + let instr_kont = + scope + ["instr_kont"] + (option + (Lazy_vec.encoding + (Lazy_vec.encoding Wasm_encoding.instruction_encoding))) + in let no_datas_in_func = value ["no-datas-in-funcs"] Data_encoding.bool in case "MKElaborateFunc" - (tup4 ~flatten:true func_types func_bodies func_kont no_datas_in_func) + (tup5 + ~flatten:true + func_types + func_bodies + func_kont + instr_kont + no_datas_in_func) (function | Decode.MKElaborateFunc - (func_types, func_bodies, func_kont, no_datas_in_func) -> - Some (func_types, func_bodies, func_kont, no_datas_in_func) + (func_types, func_bodies, func_kont, instr_kont, no_datas_in_func) + -> + Some + (func_types, func_bodies, func_kont, instr_kont, no_datas_in_func) | _ -> None) - (fun (func_types, func_bodies, func_kont, no_datas_in_func) -> - MKElaborateFunc (func_types, func_bodies, func_kont, no_datas_in_func)) + (fun (func_types, func_bodies, func_kont, instr_kont, no_datas_in_func) -> + MKElaborateFunc + (func_types, func_bodies, func_kont, instr_kont, no_datas_in_func)) let module_funcs_encoding = scope ["module";
