…ine artifacts Add a post-build step to global-build-job.yml that collects compiled object files (.obj/.o) for the 102 source files modified in PR dotnet#127295 (Remove Unused Includes) and publishes them as pipeline artifacts. - New script: eng/pipelines/collect-obj-files.ps1 Searches artifacts/obj/ for object files matching the 102 source basenames and copies them to a staging directory. - Modified: eng/pipelines/common/global-build-job.yml Added pwsh step + PublishBuildArtifacts task after the build step. Runs on every build leg, publishes per-leg artifacts named ObjFiles_<os>_<arch>_<config>. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
Adds a CI step to collect compiled object files (.obj/.o) for 102 specific source files modified in PR #127295 ("Remove Unused Includes") and publishes them as build artifacts for size-comparison analysis.
Changes:
- New PowerShell script
collect-obj-files.ps1that searchesartifacts/objfor object files matching a hardcoded list of 102 source basenames and copies matches to a staging directory. - Updates
global-build-job.ymlto invoke the script and publish the resulting object files viaPublishBuildArtifacts@1, scoped per OS/arch/config.
Show a summary per file
| File | Description |
|---|---|
| eng/pipelines/collect-obj-files.ps1 | New script enumerating 102 source basenames, recursively scanning obj dir, stripping .cpp/.c + .obj/.o suffixes, and copying matches preserving relative path. |
| eng/pipelines/common/global-build-job.yml | Adds two pipeline steps: invoke the collection script, then publish the staged object files as a per-leg build artifact. |

Please open a discussion at https://github.com/dotnet/runtime/discussions to explain the objectives behind these PRs first. We need to understand the rationale for these changes. As it stands, I don't think we want to publish intermediate objects even for experiments. |
