This is a complete rewrite of the original C++ implementation in Rust, designed as a course assignment stub for students to learn about virtual machine implementation. -Language has simple C-style syntax and is intentionally rather basic. -Language has 3 types: - - 64-bit integer type, called `int` - - ANSI C compatible double type, called `double` - - immutable strings, called `string` (C equivalent: char*) +## MVM Language -Every variable is scoped, scope is marked with curly braces (`{` -and `}`). Variable has to be declared before first use, otherwise -translation error will happen. +The MVM language is a simple C-style language with the following features: -Values in variable could be modified with traditional C-style -expressions, like `x = 2 + y * 3`; with traditional C-style operators -precedence, i.e. aforementioned expression is evaluated as -`x = (2 + (y * 3))`; +### Data Types +- `int`: 64-bit signed integer +- `double`: IEEE 754 double precision floating point +- `string`: Immutable UTF-8 strings -Variables in topmost scope could be bound to `Var` class instances, -to allow interoperability between MVM programs and C++. +### Language Features +- Variable declarations with optional initialization +- Arithmetic operations: `+`, `-`, `*`, `/`, `%` +- Comparison operations: `==`, `!=`, `<`, `<=`, `>`, `>=` +- Logical operations: `&&`, `||`, `!` +- Bitwise operations: `&`, `|`, `^` +- Assignment operations: `=`, `+=`, `-=`, `*=`, `/=` +- Control flow: `if/else`, `while`, `for` loops +- Functions with parameters and return values +- Print statements for output -Literals can be: - - integer, such as 42 or 123456789012345 - - double, such as 42.0 or 1e-18 - - string, such as '42' or 'Hello \\'World\\'\n' +### Example Programs -Flow control is as following: - - `for` loop, with semantics: -``` - for (i in -10..x) { - print('i=', i, '\n'); +```mvm +// Basic arithmetic +int x = 10; +double y = 3.14; +print('x + y = ', x + y, '\n'); + +// Control flow +if (x > 5) { + print('x is greater than 5\n'); +} else { + print('x is not greater than 5\n'); +} + +// Loops +for (i in 1..10) { + print('i = ', i, '\n'); +} + +// Functions +function int factorial(int n) { + if (n <= 1) { + return 1; + } else { + return n * factorial(n - 1); } +} + +print('factorial(5) = ', factorial(5), '\n'); ``` - - `if` conditions, such as + +## Architecture + +The MathVM implementation consists of several key components: + +### 1.

Submit a pull request + +## License + +This project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details. + +## Acknowledgments -We provide generic source -> AST (abstract syntax tree) translator, -so that implementors can focus on VM-specific issues. It means we -give scanner and top-down parser, generating tree of AST nodes, -representing program structure. It is up to implementors to provide -remaining pieces for fully functional VM. +- Original C++ implementation by the Virtual Machines course instructors +- Rust community for excellent tooling and documentation +- Students and teaching assistants for feedback and contributions -## Tests +## Getting Help -Directory `tests` contains set of tests on basic language features, -along with test scripts `taskN.py`. Generally, for every MVM program -we have an .expect file, which contains expected result of execution -for given MVM program. +If you encounter issues: +1. Check the test output for specific error messages +2. Review the documentation in `src/lib.rs` +3. Look at the example programs in `tests/` +4. Ask questions in the course forum or office hours -## Source tree layout +Remember: This is a learning exercise. The goal is to understand how virtual machines work, not just to pass the tests. Take time to understand each component and how they work together. -Folder 'include' contains generic declarations of language constructs -(as AST nodes), set of bytecodes with description, and certain basic -interfaces. +## Implementation Status -Folder `tests` contains MVM tests. Feel free to implement your own -tests. +### ✅ Completed +- [x] Basic project structure and build system +- [x] Lexer and parser for MVM language +- [x] AST representation and pretty printer +- [x] Type system and value representation +- [x] Bytecode instruction set +- [x] Basic AST interpreter +- [x] Bytecode generator (partial) +- [x] Test framework and integration tests +- [x] Error handling and reporting -Folder `vm` contain source code for the VM. +### 🚧 In Progress +- [ ] Complete bytecode interpreter +- [ ] Control flow implementation +- [ ] Function calls and scoping +- [ ] Native function interface -## Building +### 📋 TODO +- [ ] JIT compiler integration +- [ ] Performance optimizations +- [ ] Advanced debugging features +- [ ] IDE integration support -Build shall be pretty straightforward, just type `make` in command -line (known to work with MacOS and Linux). Use `make OPT=1` for an -optimized build. `NO_JIT` variables controls if JIT dependencies -shall be compiled in. -Create your own implementation in `students//` -folder, using `students//_example` template. +The implementation provides a solid foundation for students to build upon. The core infrastructure is in place, and the main task is to complete the missing functionality in the interpreters and bytecode generator. \ No newline at end of file diff --git a/common.mk b/common.mk deleted file mode 100644 index 905b554d..00000000 --- a/common.mk +++ /dev/null @@ -1,142 +0,0 @@ -OUT = $(ROOT)/build -ifeq ($(OPT),) - CFLAGS = -g3 - OBJ = $(OUT)/debug - BIN = $(OUT)/debug -else - OBJ = $(OUT)/opt - BIN = $(OUT)/opt - CFLAGS = -O2 -endif -OS := $(shell uname -s) - -MATHVM = $(BIN)/mvm -MATHVMTGZ = ../MathVM.tgz - -CXX ?= g++ -CFLAGS += -Wall -Werror -D_REENTRANT -fPIC $(USER_CFLAGS) -LIBS_ROOT = $(VM_ROOT)/libs -ASMJIT_CFLAGS = -Wno-error -INCLUDE = -I$(VM_ROOT)/include -I$(LIBS_ROOT) -VM_INCLUDE = -I$(VM_ROOT)/vm -ASMJIT_INCLUDE = -I$(LIBS_ROOT)/asmjit -USER_INCLUDE = -I$(ROOT) -DEFS = $(USER_DEFS) -D_POSIX_SOURCE -THREAD_LIB = -lpthread -OBJ_SUFF = .o -LIBS = $(USER_LIBS) $(THREAD_LIB) - - -ifneq (,$(findstring MINGW,$(OS))) - DEFS += -DMATHVM_WIN -else - DEFS += -DMATHVM_POSIX - LIBS += -ldl -endif - -ifneq (,$(findstring Darwin,$(OS))) - ifneq ($(WITH_SDL),) - DEFS += -I/opt/local/include - LIBS += -L/opt/local/lib -framework cocoa -lSDLmain - endif - DEFS += -D_DARWIN_C_SOURCE -endif - -ifneq (,$(findstring Linux,$(OS))) - LIBS += -rdynamic -endif - -ifneq ($(WITH_SDL),) - DEFS += -DMATHVM_WITH_SDL - LIBS += $(shell sdl-config --libs) - CFLAGS += $(shell sdl-config --cflags) -endif - -ASMJIT_OBJ_DIR = $(OBJ)/asmjit -ifneq ($(NO_JIT),1) -ASMJIT_OBJ = \ - $(ASMJIT_OBJ_DIR)/arch$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/assembler$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/codebuilder$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/codecompiler$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/codeemitter$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/codeholder$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/constpool$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/cpuinfo$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/func$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/globals$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/inst$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/logging$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/operand$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/osutils$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/regalloc$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/runtime$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/string$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/utils$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/vmem$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/zone$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86assembler$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86builder$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86compiler$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86inst$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86instimpl$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86internal$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86logging$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86operand$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86operand_regs$(OBJ_SUFF) \ - $(ASMJIT_OBJ_DIR)/x86regalloc$(OBJ_SUFF) -DEFS += -DASMJIT_BUILD_X86 -CFLAGS += -Wno-bool-compare -else -ASMJIT_OBJ = -endif - -MATHVM_OBJ = \ - $(ASMJIT_OBJ) \ - $(OBJ)/ast$(OBJ_SUFF) \ - $(OBJ)/mathvm$(OBJ_SUFF) \ - $(OBJ)/parser$(OBJ_SUFF) \ - $(OBJ)/scanner$(OBJ_SUFF) \ - $(OBJ)/utils$(OBJ_SUFF) \ - -default: $(OBJ)/.dir all - -tar: - rm -f $(MATHVMTGZ) - tar czf $(MATHVMTGZ) ../MathVM - - -$(OBJ)/%$(OBJ_SUFF): $(VM_ROOT)/vm/%.cpp \ - $(OBJ)/.dir \ - $(VM_ROOT)/include/ast.h $(VM_ROOT)/include/mathvm.h \ - $(VM_ROOT)/include/visitors.h \ - $(VM_ROOT)/vm/scanner.h $(VM_ROOT)/vm/parser.h \ - $(VM_ROOT)/common.mk - $(CXX) -c $(DEFS) $(CFLAGS) $(INCLUDE) $(VM_INCLUDE) $< -o $@ - -$(OBJ)/%$(OBJ_SUFF): $(ROOT)/%.cpp \ - $(OBJ)/.dir \ - $(VM_ROOT)/include/ast.h $(VM_ROOT)/include/mathvm.h \ - $(VM_ROOT)/include/visitors.h \ - $(VM_ROOT)/vm/scanner.h $(VM_ROOT)/vm/parser.h \ - $(VM_ROOT)/common.mk $(USER_DEPS) - $(CXX) -c $(DEFS) $(CFLAGS) $(INCLUDE) $(VM_INCLUDE) $< -o $@ - -$(ASMJIT_OBJ_DIR)/x86%$(OBJ_SUFF): $(LIBS_ROOT)/asmjit/x86/x86%.cpp $(OBJ)/.dir - $(CXX) -c $(DEFS) $(CFLAGS) $(ASMJIT_CFLAGS) $(INCLUDE) $(ASMJIT_INCLUDE) $< -o $@ - -$(ASMJIT_OBJ_DIR)/%$(OBJ_SUFF): $(LIBS_ROOT)/asmjit/base/%.cpp $(OBJ)/.dir - $(CXX) -c $(DEFS) $(CFLAGS) $(ASMJIT_CFLAGS) $(INCLUDE) $(ASMJIT_INCLUDE) $< -o $@ - -$(OBJ)/.dir: - mkdir -p $(OUT) - mkdir -p $(OBJ) - mkdir -p $(ASMJIT_OBJ_DIR) - mkdir -p $(BIN) - touch $@ - -clean: - rm -rf $(OUT) - -.PHONY : clean dirs all tar default - diff --git a/examples/basic.mvm b/examples/basic.mvm new file mode 100644 index 00000000..edeebc8f --- /dev/null +++ b/examples/basic.mvm @@ -0,0 +1,4 @@ +int x = 42;

The reason is that loops - //! generally use backward jumps and conditions usually use forward jumps. - //! However this behavior can be overridden by using instruction prefixes. - //! If this option is enabled these hints will be emitted. - //! - //! This feature is disabled by default, because the only processor that - //! used to take into consideration prediction hints was P4.

Hint that is important for register liveness analysis. It tells the - //! compiler that the destination operand will be overwritten now or by - //! adjacent instructions. CodeCompiler knows when a register is completely - //! overwritten by a single instruction, for example you don't have to - //! mark "movaps" or "pxor x, x", however, if a pair of instructions is - //! used and the first of them doesn't completely overwrite the content - //! of the destination, CodeCompiler fails to mark that register as dead. - //! - //! X86/X64 Specific - //! ---------------- - //! - //! - All instructions that always overwrite at least the size of the - //! register the virtual-register uses , for example "mov", "movq", - //! "movaps" don't need the overwrite option to be used - conversion, - //! shuffle, and other miscellaneous instructions included. - //! - //! - All instructions that clear the destination register if all operands - //! are the same, for example "xor x, x", "pcmpeqb x x", etc... - //! - //! - Consecutive instructions that partially overwrite the variable until - //! there is no old content require the `overwrite()` to be used. Some - //! examples (not always the best use cases thought): - //! - //! - `movlps xmm0, ?` followed by `movhps xmm0, ?` and vice versa - //! - `movlpd xmm0, ?` followed by `movhpd xmm0, ?` and vice versa - //! - `mov al, ?` followed by `and ax, 0xFF` - //! - `mov al, ?` followed by `mov ah, al` - //! - `pinsrq xmm0, ?, 0` followed by `pinsrq xmm0, ?, 1` - //! - //! - If allocated variable is used temporarily for scalar operations. For - //! example if you allocate a full vector like `X86Compiler::newXmm()` - //! and then use that vector for scalar operations you should use - //! `overwrite()` directive: - //! - //! - `sqrtss x, y` - only LO element of `x` is changed, if you don't use - //!

It is at least 64-bytes so CodeEmitter can guarantee the alignment -// up to 64 bytes, which is the size of a cache-line and it's also required by -// AVX-512 aligned loads and stores. Alignment requirements can grow in the future, -// but at the moment 64 bytes is safe (we may jump to 128 bytes if necessary or -// make it configurable). -// -// - Keep memory manager information outside of the allocated virtual memory -// pages, because these pages allow machine code execution and there should -// be not data required to keep track of these blocks. Another reason is that -// some environments (i.e. iOS) allow to generate and run JIT code, but this -// code has to be set to [Executable, but not Writable]. -// -// - Keep implementation simple and easy to follow. -// -// Implementation is based on bit arrays and binary trees. Bit arrays contain -// information related to allocated and unused blocks of memory. The size of -// a block is described by `MemNode::density`. Count of blocks is stored in -// `MemNode::blocks`. For example if density is 64 and count of blocks is 20, -// memory node contains 64*20 bytes of memory and the smallest possible allocation -// (and also alignment) is 64 bytes. So density is also related to memory -// alignment. Binary trees (RB) are used to enable fast lookup into all addresses -// allocated by memory manager instance. This is used mainly by `VMemPrivate::release()`. -// -// Bit array looks like this (empty = unused, X = used) - Size of block 64: -// -// ------------------------------------------------------------------------- -// | |X|X| | | | | |X|X|X|X|X|X| | | | | | | | | | | | |X| | | | |X|X|X| | | -// ------------------------------------------------------------------------- -// (Maximum continuous block) -// -// These bits show that there are 12 allocated blocks (X) of 64 bytes, so total -// size allocated is 768 bytes.
