toy handwritten assembler, emulator, compiler, toolchain for a lightweight RISC architecture
documentation and specifications (arch, asm) are available in doc.
grab submodules:
git submodule update --init --recursiveinstall dependencies:
- C compiler
- D compiler
./script/build_tools.shtools you now have:
./src/irretool/irretool(irre multitool)./tools/chcc/chibicc(c->irre compiler)
// my_prog.c
int add(int a, int b) {
return a + b;
}
int main() {
int a = 3;
int b = 4;
int sum = add(a, b);
return sum;
}now build and run:
# compile to binary
./script/irrecc -v -o my_prog.bin my_prog.c
# run in emulator
./src/irretool/irretool -v emu my_prog.bin- run a compiled program and log commits and snapshots
./src/irretool/irretool -v emu --commit-log --save-commits t1_trace.bin my_prog.bin- run analyzer
./src/irretool/irretool analyze --ift --pl --pl-threads 4 --ift-graph --ift-graph-analysis --ift-save-graph t1_graph.dot t1_trace.bin
