PGO build failures |
||||
Issue descriptionThe PGO bots have been quite flaky recently, there's different cause for failure: - During instrumentation or optimization step: fatal error LNK1181: cannot open input file 'libEGL.dll.lib' [1]: This is probably due to an invalid dependency? - During the 'merge PGC files step': PGOMGR : fatal error PG0166: Missing or invalid stream 'value/''_ltcg_' in 'C:\b\build\slave\chromium-win-x64-pgo-builder\build\src\out\Release_x64\chrome_child.pgd'. [2] -> No idea what could cause this. - During optimization step: No profile data was merged into './chrome_child.pgd', profile-guided optimizations disabled : Because all the profiling benchmarks failed.

Update on this: - libEGL.dll.lib issue: Haven't seen this for a while, the problem might have been fixed in Chrome? - 'merge PGC files step': Should be fixed now (with https://chromium-review.googlesource.com/c/528354/) - The issue with Telemetry not running any benchmark, it looks like a timeout issue, https://codereview.chromium.org/2932063003/ should fix this.

Lowering the priority of the PGO bugs as we've switched the official build to Clang. I'll close these bugs once we decide that we won't support the VS build anymore.
