[a-siva]

Intended Change

Remove support for ia32 from the dart-sdk completely starting with Dart SDK version 3.8.0. The ia32 distributions for all releases starting with 3.8.0 will be removed on dart.dev and other release channels.

Rationale

This variant is not in use anymore

Expected Impact

Users will not be able to install and run Dart SDK on ia32 architecture based systems.

Projects known to break

None

Projects that will not be affected

Flutter
All Google internal projects

Migration Steps

Any project affected by this change needs to switch to the x64 artifacts or stay on Dart SDK version 3.7.0.

Will this remove support for Dart compiled to IA32?

I had a minor concern over 32 bit DLLs which are common on Windows that will not be able to be connected through IPC by deploying a Dart solution.

Say, a Flutter app needs to interact with an old scanner library and can't load libtwain and the vendor library of the scanner on a different process written in dart, because Dart dropped IA-32 support, so it would need to be written in a different language that didn't drop x86 support.

Damn, there's so much legacy on Windows.

The different process written in Dart could still run using Dart 3.7
