This is the repository of our paper presented at the ACSAC 2025.
Paper: (to appear)
This artifact contains the prototype implementation of SMORE, as described in Sections 6 and 7 of our paper. It includes modified LLVM 15.0.7 (for compiler instrumentation), a ported RIOT-OS 2024.01 with the SMORE runtime library, and a ported newlib used as the standard C library. The repository also provides benchmark programs (BEEBS, CoreMark, Juliet Test Suite cases) and scripts to reproduce the evaluation results.
Dependencies: Ubuntu 22.04 LTS, LLVM 15.0.7, newlib (ported for SMORE), Arm GNU Toolchain (arm-none-eabi-gcc 10.3.1, 2021.07 release), Python ≥3.9, make.
Infrastructure: Requires the STM32 Nucleo-L552ZE-Q development board (Cortex-M33, Armv8-M). Public cloud infrastructure (e.g., CloudLab, Chameleon, FABRIC) is not applicable due to the hardware requirement.
Expected runtime: < 1 hour for benchmarks.
Execution: Run install.sh to install dependencies, then execute the scripts under claims/ (e.g., claims/run.sh).

Development boards NUCLEO-L552ZE-Q by STMicroelectronics (Available 8 MPU Regions, 256 KB SRAM) Ubuntu 22.04 LTS Embedded ARM cross-compiler toolchain
$ sudo apt install gcc-arm-none-eabi
$ pip3 install pyserial
$ git clone https://github.com/cslab-pnu/SMORE.git
$ cd SMORE
Let's install SMROE toolchains. Building LLVM can take some time.
$ ./install.sh
Then, load the environment in your current shell:
$ source env.sh
To check the test results of SMORE, the development board must be connected to the terminal as shown below.
In a new terminal, enter the following:
$ ./pyterm.sh
Expected output:
2025-09-08 10:59:22,561 # Connect to serial port /dev/ttyACM0
Welcome to pyterm!
Type '/exit' to exit.
Compile the example programs in the artifact directory.
Coremark (claim)
In a new terminal, enter the following:
$ cd claim/
$ ./run.sh
Expected output:

The execution cycle is displayed. The parts marked as errors in the output appear because the built-in timer of CoreMark was not ported, and they do not indicate that the execution itself is incorrect.
