Indigo

Indigo is a compiler for a C-like toy language (named "SysY") into ARMv7a assembly, written in C++ 17.

Building

Environment:

• CMake and Make
• GCC >= 9.2.0 or Clang > 8.0

Steps:

mkdir build && cd build
cmake .. && make -j8
./compiler -h    # for help information

Architecture

Testing

Environment:

• Building environment
• GCC
• Clang (if you need to compare compiler speeds)
• Python >= 3.7
  • Packages: colorlog, tqdm

Steps:

mkdir -p output

# Test against official functional tests
python3 scripts/test.py build/compiler \
    test_codes/sysyruntimelibrary/libsysy.a test_codes/functional_test -r
    
# Test against custom tests
python3 scripts/test.py build/compiler \
    test_codes/sysyruntimelibrary/libsysy.a test_codes/upload -r -t 90
    
# Test against performance tests
python3 scripts/test.py build/compiler \
    test_codes/sysyruntimelibrary/libsysy.a test_codes/performance_test -r -t 120 -z
    
# Compare performance with GCC and Clang, assuming all tests are passed
python3 scripts/speed_compare.py build/compiler \
    test_codes/sysyruntimelibrary/libsysy.a \
    test_codes/sysyruntimelibrary/stdlib.c \
    test_codes/performance_test -r -t 120
