[PATCH] D135590: [ThinLTO][ELF] Add a ThinLTO warning if cache_size_bytes or cache_size_files is too small for the current link job.

[Ying Yi via Phabricator via llvm-commits]

MaggieYi updated this revision to Diff 468959.
MaggieYi added a comment.

Update the patch following the reviewers comments, which include:

1. Just emit a warning the first time a file is pruned due to either of the size/number limits and add a test for it.
2. Use python and command substitution via $() in the RUN line to compute the size of the files and +/- 5 from the total.
3. Use lld 'warn()' to generate the warning.
4. Use ';;' for Non-RUN non-CHECK comments.
