[release/8.0.1xx-xcode15.1] Enable dedup optimization in FullAOT mode only #20701

Closed vs-mobiletools-engineering-service2 closed 1 week ago

vs-mobiletools-engineering-service2 commented 3 weeks ago

Description

This PR enables the dedup optimization in FullAOT mode only. The optimization can only run in FullAOT mode with complete application context. Without it, the AOT compiler may fail to collect all generic instances, and the runtime can't find them as they are searched in the dedup assembly.

Changes

This PR updates the SDK targets to enable dedup optimization in FullAOT mode only. This change doesn't depend on any runtime changes.

Verification

This PR also introduces partial AOT tests. They inspect the bundle for aot-instances.dll, which shouldn't be generated in a partial AOT compilation setup. Additionally, basic functionality is tested by asserting at app startup.

Additional notes

This change should be backported to .NET 8 as well.

Fixes https://github.com/dotnet/runtime/issues/99248

Backport of #20687
