Type-V is a virtual machine and runtime environment for type-c programs. While the VM can be used for generic purposes, its instructions are heavily optimized for type-c source code, such as offset-based data types (structs, arrays, classes, interfaces, shadow structs, etc), built-in concurrency, etc.

Status

As for the right now, the VM is still experimental and lacking major features.

Progress:

• Assembler
• Instruction set specification
• Processes (not to be confused with OS processes)
• VM API passes valgrind checks (doesn't count bytecode allocated memory since it's supposed to be handled by GC)
• Non-blocking I/O
• Garbage collection
• Unit tests

Bytecode example:

As of the right now, the instructions themselves are solid, however the instruction names in the assembler are subject to change.
