One action needed to retire Talos on opt builds (in favor of pgo) is to be able to run talos on Try. At the moment, on the tc-migration branch, we're able to trigger talos on win{32,64}-pgo, but not on linux[1]. I guess there's a change to do in try_option_syntax.py[2]. I'm looking into it.

I see Talos doesn't run on Linux 32[1]. Renaming bug accordingly. [1] https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&filter-searchStr=talos&fromchange=30ea2905130e85f9e1d8d56fa3097901eec6514b&tochange=60a5308fa987676fa5ed9fd5b3ad6c9938af0539

Comment on attachment 8889418 [details] Bug 1382725 - Try: Make Talos run on linux64-pgo Clearing review request while we discuss whether AWSY should run on try.

AWSY was filtered out by remove_linux_pgo_try_talos() in bug 1272113. I don't know what's changed since then, however, I know removing the whole function doesn't make awsy appear on try[1]. My guess is that's because awsy isn't listed at [2] [1] https://treeherder.mozilla.org/#/jobs?repo=try&revision=3b424017947628249cdc05ab01c36b5822513cda&filter-tier=1&filter-tier=2&filter-tier=3 [2] https://dxr.mozilla.org/mozilla-central/rev/7d2e89fb92331d7e4296391213c1e63db628e046/taskcluster/ci/test/test-platforms.yml#75

It was set to make sure awsy won't run on pgo build accidentally. As long as test-platforms.yml is not changed it should be safe to remove.
