[beta][vm] Evaluate abstract origin DIE offsets sooner in DWARF assembly output. This is a cherry pick of the change which fixes b/410018517 (Flutter AOT snapshotting step timing out with Xcode 16.x) Issue description : Xcode 16.x has a newer version of clang tools and the assembler in this version was taking a long time to assemble the output from the AOT compiler. What is the fix : This change greatly improves assembler performance in XCode 16, presumably by convincing the assembler it doesn't need to keep track of relocations for abstract origin labels. Why Cherry Pick : The cherry pick is needed as a number of iOS developers have to switch to XCode 16 as Apple is dropping support for Xcode 15.4 and any apps built with 15.4 can't be published to the App Store after April 24th. Risk : low TEST=ci Bug: https://github.com/dart-lang/sdk/issues/43299 Bug: b/410018517 Change-Id: If866f0bca7588867e4a30512b5a331dbd46a3e0d Cherry-pick: https://dart-review.googlesource.com/c/sdk/+/422540 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/425982 Reviewed-by: Slava Egorov <vegorov@google.com> Commit-Queue: Siva Annamalai <asiva@google.com>
Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
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).
Dart is free and open source.
See LICENSE and PATENT_GRANT.
