Small utility to analyse stack size for rust libraries.
poetry install
Also requires that cargo and llvm-readobj are on your PATH.
On Mac, llvm-readobj can be installed using Homebrew:
brew install llvm
For convenience, rust_stack_analysis will automatically add Homebrew's default
LLVM bin directory to PATH while attempting to execute llvm-readobj.
Until rustc's -Z emit-stack-size feature stabilizes (rust-lang/rust#54192),
you must have the nightly toolchain installed.
rustup toolchain install nightly
Enter the poetry shell:
poetry shell
From the root of your project:
analyse-rust-stack build
Pass any additional flags through to cargo (e.g.):
analyse-rust-stack build -- --no-default-features --target thumbv7em-none-eabi
Now request analysis (e.g.):
analyse-rust-stack analyse target/thumbv7em-none-eabi/release/libgateway_nrf52840_rust.a
