Environment

• Ubuntu 20.04.2 LTS x86_64 (5.4.0-72-generic)
• g++ 9.3.0-17 / clang 8.0.1-9 (either one)
• llvm 8.0.1
• flex 2.6.4
• bison 3.5.1

Usage

Prerequisites

For building:

sudo apt install -y llvm-8 llvm-8-dev llvm-8-tools build-essential
sudo apt install -y clang-8  # Unnecessary if you use gnu-g++ as CXX

For style formatting:

sudo apt install -y clang-format-8 fpc

Makefile

Build only:

make

Test specified case:

./PasGo <path/to/pascal/file>

Build and test all cases:

make test

Build and test and print all test output:

make print_output

What will the program PasGo do?

1. generate AST at "./a.tree"
2. generate bitcode at "./a.bc"
3. run the code

What will the make test do?

1. put the stdout of program at "tgt/$CASE/$CASE(debug output).txt"
2. put tree and bc at ""tgt/$CASE/"
3. run bitcode using llvm interpreter and put the output at "tgt/$CASE/$CASE(lli output).txt"
4. generate IR file using llvm disassembler at "tgt/$CASE/$CASE.ll"
5. generate assembly file using llvm compiler at "tgt/$CASE/$CASE.s"(using x86_64 here, but can be specified in Makefile)
