The stack height metering for functions containing CallIndirect was wrong. The code did not take into consideration that is pops one value from the stack. The effect was that the stack height of functions using this instruction was higher than its real height.
wasm-utils
Collection of WASM utilities used in pwasm-ethereum and substrate contract development
Build tools for cargo
Easiest way to use is to install via cargo install:
cargo install pwasm-utils-cli --bin wasm-build
Symbols pruning (wasm-prune)
cargo install pwasm-utils-cli --bin 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)
cargo install pwasm-utils-cli --bin wasm-gas
wasm-gas <input_wasm_binary.wasm> <output_wasm_binary.wasm>
API
All executables use corresponding api methods of the root crate and can be combined in other build tools.
