llvm-practice: A C++ repository from Vokerlee

Description of subprojects

All projects are related to different LLVM aspects:

graphics_app — application (GameOfLife) written via GTK4 & SDL libraries
- Idea: implement LLVM pass for dynamic instruction statistics collection, create own ISA most preferable for collected trace via pass.
- Detailed description see in the folder.
graphics_asm2ir — create & implement own ISA, assembler & LLVM IR generator.
- Idea: possibility to interpret assembler-file via LLVM IR generation.
- GameOfLife was written in such assembler and interpreted (see examples).
graphics_lang2ir — implement language front-end of imperative language via flex & bison generating LLVM IR for the following LLVM IR compilation into binary file (+ linkage with own standard library).
- Idea: possibility to compile file of own programming language into binary file with linkage with own standard library (primitive i/o, etc).
- Detailed description see in the folder.

graphics_llvm_backend — implement own LLVM back-end of RISC-V-like ISA (64 bits) with graphics extension & clang intrinsics.

Build commands:

LLVM build:

cmake -S llvm -B build -G Ninja -DLLVM_ENABLE_PROJECTS="clang" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=On -DLLVM_TARGETS_TO_BUILD=GRISCV -DLLVM_INCLUDE_TESTS=OFF
cmake --build build

Compile example:

./build/bin/clang -c -O0 src.c -o src.o --target=griscv
./build/bin/clang -S -O0 src.c -o src.s --target=griscv
./build/bin/clang -S -emit-llvm -O0 src.c -o src.ll --target=griscv

graphics_riscv_simulator — RISC-V simulator with support of added graphics extensions.
- Idea: possibility to execute built binary file via LLVM back-end with support of graphics instructions.
- Usage example (GameOfLife example):
  - ```
  mkdir build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release && make
  ./rvsim ~/llvm-project-grisc-v/griscv_examples/gameoflife.o
```
