The code assumed that the number of `Local` and number of locals is the same thing. In reality though it is not. `Local` actually represents a group of locals with the same type. The group can declare more than one variable and the number of them is returned by `Local::count`. In this PR we acknowledge this fact. Along the way we add a checked arithmetic for locals_count and max_stack_height summation.
pwasm-utils
A collection of WASM utilities used in pwasm-ethereum and substrate contract development.
This repository contains the package pwasm-utils which consists of a library crate
and a collection of cli binaries that make use of this library.
Installation of cli tools
cargo install pwasm-utils --features cli
This will install the following binaries:
- wasm-build
- wasm-check
- wasm-ext
- wasm-gas
- wasm-pack
- wasm-prune
- wasm-stack-height
Symbols pruning (wasm-prune)
wasm-prune <input_wasm_binary.wasm> <output_wasm_binary.wasm>
This will optimize WASM symbols tree to leave only those elements that are used by contract call function entry.
Gas counter (wasm-gas)
For development puposes, raw WASM contract can be injected with gas counters (the same way as it done by pwasm-ethereum/substrate runtime when running contracts)
wasm-gas <input_wasm_binary.wasm> <output_wasm_binary.wasm>
