Open source Cheerp, from Leaning Technologies, is based on LLVM, which features a set of modular, reusable compiler technologies. Version 1.2, introduced this week, "comes with some big performance improvements, both in execution time and in startup time," according to a blog post by Leaning Technologies CEO Stefano De Rossi.
Also new in version 1.2 are Runtime Type Information support, dynamic_cast, and covariant return types. "Cheerp now also experimentally supports the module pattern to isolate generated code from other scripts," De Rossi said.
