Full mark assignment of Advanced Compiler Principle course taught by Lian Li, ICT, CAS.

Detailed introduction in corresponding directory.

• Assignment 1 (AST_Interpreter)
  • Implement a simple interpreter based on Clang frontend.
    • Support a subset of C syntax.
    • Basic input & output of int, i.e. GET() and PRINT().
    • Basic dynamic memory allocation, i.e. MALLOC() and FREE().
• Assignment 2
  • Implement a flow-insensitive function pointer transitive closure calculation program using SSA representation in LLVM backend.
• Assignment 3
  • Implement flow-sensitive, field-insensitive and context-insensitive inter-procedure pointer analysis using SSA representation in LLVM backend.

In every assignment/testcase folder, contains testcases, standard answers and judging scripts.

• ast-interpreter: Soft link to assignment executable.
• judge.py: Judge script using ast-interpreter to grade your assignment.
• test%02d.c: Testcases.
• lib*.c: Dependencies for judging.

WARNING: If you want to test your own implementation via this judge script, make sure to

• Print a \n in PRINT() invocation
• Send your output to STDOUT.

• llvmassignment: Soft link to assignment executable.
• compile.py: Compile test%02d.c to test%02d.bc which can be read by assignment executable.
• judge.py: Judge script using llvmassignment to grade your assignment.
• test%02d.c and test%02d.bc: Testcases.
• std%02d.txt: Standard answers.

WARNING: If you want to test your own implementation via this judge script, make sure that

• The output result is sorted according to line number as first key ascendingly, function name as second key lexicographically ascendingly.
• Sending your output to STDOUT.

• ASSIGNMENT_DEBUG: Reading C filename instead of C code from command line interface argument.
• ASSIGNMENT_DEBUG_DUMP: Dump detailed debug messages.

• ASSIGNMENT_DEBUG_DUMP: Dump detailed debug messages.

• ASSIGNMENT_DEBUG_DUMP: Dump detailed debug messages.
• INTRA_PROCEDURE_ANALYSIS: Switch option to do intra- or inter-procedure analysis in program.

docker pull registry.cn-hangzhou.aliyuncs.com/test_tc/llvm_hw:0.2

docker pull lczxxx123/llvm_10_hw:0.2

1. Create the container and exit.

docker run -it llvm_10_hw:0.2 --name llvm_ACPA /bin/bash
exit

2. Copy codes and testcases into the container.

docker cp $ASSIGNMENT_FOLDER llvm_ACPA:/root/
docker cp $TESTCASES llvm_ACPA:/root/

3. Compile your assignment.

docker exec llvm_ACPA mkdir ${tempBuildFolder}
docker exec -w ${tempBuildFolder} llvm_ACPA
cmake -DLLVM_DIR=/usr/local/llvm10ra/ $ASSIGNMENT_FOLDER
docker exec -w ${tempBuildFolder} llvm_ACPA make

4. Run executable in container of path ${tempBuildFolder}.

docker exec -it llvm_ACPA /bin/bash

sudo docker cp llvm_ACPA:/usr/local/llvm10ra/ /usr/local/llvm10ra/
