Removes an unnecessary change to the names of type testing stubs that allowed name collisions to happen. Old commit message: The flag can be used when creating AOT snapshots. The resulting file can be used with package:vm/dwarf/convert.dart to convert DWARF-based stack traces to stack traces with function, file, and line number information. Currently the saved file will be an ELF file with DWARF debugging information, but this is subject to change in the future. To avoid being affected by any changes in format, read the DWARF information from the file using Dwarf.fromFile() in package:vm/dwarf/dwarf.dart. Also adds --dwarf-stack-traces to the VM global flag list, so its value at compilation will be read out of snapshots by the precompiled runtime. Fixes https://github.com/dart-lang/sdk/issues/39512, which was due to a missing compiler::target:: prefix for Instructions::HeaderSize() in BlobImageWriter::WriteText(). Exposes the information suggested in https://github.com/dart-lang/sdk/issues/39490 so that package:vm/dwarf can appropriately convert absolute PC addresses to the correct virtual address for a given DWARF line number program.

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 has 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).
