[rookiejava]

Summary

This PR adds initial Kotlin/Native Tizen target support across the Native target model, Kotlin Gradle Plugin APIs, and related target wiring.

Added targets:

• tizen_arm32
• tizen_arm64
• tizen_x64

What Was Added

Native target model and configuration

• Added Tizen targets to KonanTarget
• Added initial Tizen target configuration in konan.properties
• Enabled Tizen targets in HostManager
• Added Tizen platform width mappings

Gradle plugin and public API wiring

• Added public KGP DSL for Tizen native targets
• Added common source set conventions for shared Tizen source sets
• Wired Tizen targets into KGP hierarchy and ABI-related APIs

  • Adds tizenMain and tizenTest source set conventions for shared code across Tizen targets.

Modified Areas

Primary files and why they changed:

• native/utils/src/org/jetbrains/kotlin/konan/target/KonanTarget.kt
  • Added new Tizen targets.
• native/utils/src/org/jetbrains/kotlin/konan/target/HostManager.kt
  • Enabled Tizen targets in host support logic.
• kotlin-native/konan/konan.properties
  • Added target/toolchain/sysroot/linker configuration for Tizen.
  • Uses placeholder dependency IDs for Tizen toolchains until the corresponding CDN artifacts are published.
• Kotlin Gradle Plugin target / ABI / hierarchy-related files
  • Added DSL exposure and target wiring for Tizen support.
• Kotlin Gradle Plugin source set convention files
  • Added tizenMain and tizenTest common source set conventions.
• Platform width/index handling files
  • Added Tizen width mappings used by Native infrastructure.
• API dump / verification files
  • Updated generated verification outputs for the new target surface.

Local Verification

The following verifications were performed locally:

• ./gradlew compileKotlin — ✅ BUILD SUCCESSFUL
• No missing when() branches for Tizen targets detected
• No unresolved references in modified source files

Known Limitation

End-to-end verification is currently constrained by bootstrap artifact usage in local development.

During local verification, Kotlin/Native build logic still resolved HostManager from the bootstrap artifact:

• org.jetbrains.kotlin:kotlin-native-utils:2.4.0-dev-5318

Because of that bootstrap jar constraint, full end-to-end validation of Tizen target task registration and sample linking requires JetBrains CI or bootstrap-aligned internal infrastructure.

TODO

• JetBrains needs to package and upload Tizen toolchain tarballs to:
  • https://download.jetbrains.com/kotlin/native/
  • Tizen toolchains can be installed via Tizen Package Manager:
    • Tizen Studio: https://developer.tizen.org/development/tizen-studio/download/
    • VS Code Tizen Extension: https://marketplace.visualstudio.com/items?itemName=tizen.vscode-tizen-csharp
  • After installation, toolchains are located at:
    • Tizen Studio: ~/tizen-studio/tools/
    • VS Code Tizen Extension: ~/.tizen-extension-platform/server/sdktools/data/tools/
  • Required toolchain directories to package:
    • arm-linux-gnueabi-gcc-14.2/arm-tizen-linux-gnueabi (for tizen_arm32)
    • aarch64-linux-gnu-gcc-14.2/aarch64-tizen-linux-gnu (for tizen_arm64)
    • x86_64-linux-gnu-gcc-14.2/x86_64-tizen-linux-gnu (for tizen_x64)
  • Once packaged and uploaded, replace placeholder dependency IDs
    in konan.properties with the actual artifact names
• Document the konan.properties local candidate pattern for contributors using a local Tizen SDK
• Add a sample project in a follow-up PR
