[vm] Use the right stack maps between executing catch entry moves and jumping to the exception handler.

Adds a stack map to the catch block entry pc.

The alternative would be to prevent yielding to a safepoint between these two point. For throws coming from Dart or the embedding API, this is possible by unwinding the transitions before the first point and doing only a non-yielding VM->Generated between the two points. For FFI, this does not work because the final state is Native instead of Generated, and VM->Native is a blocking transition.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
