LLVM Compiler Overview version 2

General

Good day, everyone.

I’m starting this thread to get up to date on the latest developments in the Xojo compiler.

I would like to validate the comparison.

Suggestions and opinions are welcome.

Comments C#, Java, JavaScript (V8), are at the same level.

Beside “Do not use Python”, what is the conclusion ?

My personal opinion.

The C language has the best compiler on the market. XOJO performs reasonably well compared to other A-level languages. Its compiler is good.

Python isn’t bad; it depends on what you’re using it for. If you’re looking for a native compiler, you can rule out Python.

Everyone know Ruby is the best :laughing:

Note:

I forgot to add Kotlin to the table. And Ruby…

Actually I would be interested in those stats

Ruby is not generally recognized for cutting-edge compiler technology. Historically, it has relied on an interpreter-based execution model, with later performance improvements introduced through JIT compilation techniques.

My Ruby comment was sprinkled with some humor :grin:

Add two more lines. Which I consider important.

My comparison shows that Xojo is much closer to C++ and Swift than is commonly believed, because it shares the same LLVM infrastructure for optimization and native code generation.
