A standalone test-suite for AVR compilers.
Uses simavr under the hood.
git clone https://github.com/dylanmckay/avr-test-suite.git
cd avr-test-suite
# Run all tests
./run-tests.sh
There are two binaries included in this crate.
The test runner.
Usage
cd avr-test-suite
# Run all tests with avr-gcc
cargo run --bin avr-lit -- --avr-gcc
# Run specific test with avr-gcc
cargo run --bin avr-lit -- --avr-gcc tests/memory/copy-immediate-to-sram/copy_u32.cpp
# Run all tests with llvm
cargo run --bin avr-lit -- --llvm-sysroot /path/to/llvm/buildtree
# Run specific test with avr-gcc
cargo run --bin avr-lit -- --llvm-sysroot /path/to/llvm/buildtree tests/memory/copy-immediate-to-sram/copy_string.cpp
An avr simulator that will flash binaries given to it onto an emulated AVR and execute the program until it goes into indefinite sleep mode with interrupts disabled.
It will also connect the simulated UART to standard output, which can then be used by tests or other stuff.
Usage
cd avr-test-suite
# Run a program by loading it via disk
cargo run --bin avr-sim MyExecutable.elf
# Compile a file and pipe it directly into the simulator to run.
echo 'int main() { return 0; }' > main.c
avr-gcc main.c -mmcu=atmega328 -o /dev/stdout | cargo run --bin avr-sim MyExecutable
Uses the lit crate.
- Basic copying of immediate integer values to SRAM
- Memory copying from one chunk of RAM to another chunk
- Calling convention tests
- Interrupt handler tests
