| 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, etc), |
Type-V is a virtual machine and runtime environment for type-c programs. The Type-C compiler can be found at https://github.com/unlimitedsoftwareworks/type-c.
Type-V is written in C11 and has minimal dependencies.
The VM tries to store minimal RTTI and is currently very unoptimized. Type-V development goes hand in hand with the Type-C compiler.
Here are the current planne and implemented features:
- All instructions for all data types
- Closures
- Coroutines
- Source Mapping
- GC (So far only scavenger is implemented, can allocate up to 1Mb)
- JIT (Just in time compilation in 2050)
- Disassembler
- Lots of optimizations
Type-V performance is very comparable to node in interpreter mode (JIT off, since Type-V doesn't have JIT yet). Type-V even beats node on some benchmarks (unpublished).
Type-V is a runtime environment for type-c. All instructions are optimized for type-c source code, they are all typed and the VM tries to store minimal RTTI (yet somehow i feel like i'm not succeeding).

- Type-V is not production ready yet.
- Type-V is not optimized yet.
- Type-V is not secure yet.
- Type-V is not documented yet.
- Type-V is not fully tested yet.
- Type-V is not JIT'ed yet.
These benchmarks are compiled with the Type-C compiler and ran with Type-V. Currently Type-C doesn't perform any optimizations at all. So there is a lot of room for improvement.
The performance evaluation was conducted on a system powered by AMD EPYC Processor (Family 25, Model 1, Stepping 1).
