Sorry, this didn't get updated. We have had updated PGO data for the last three weeks.

now that runtime official build has over come an infra issue, this issue is now the top cause of build breaks. what is the ETA for getting it merged?

[AustinWise]

I think #91497 might need to be merged first. I'll cherry pick the changes from that PR into this one to see if that is the case.

@jeffschwMSFT what build breaks is this causing? #89311 went in last week (29-AUG) and we've had successful builds since then.

If you are talking about the LNK1264 error, I expect that is from: #91563 - specifically #91563 (comment)

[AustinWise]

It looks like #91497 does not currently contain the updated linker flags that would allow this PR to be merged.

[DrewScoggins]

Is this ready to merge?

[AustinWise]

@DrewScoggins It can be merged once the main branch contains PGO data that was produced from the main branch. Currently it appears the PGO data is being built from the 8.0 branch, which is not compatible. See #93280 for an example of PR that updates the PGO data.

Hi all, #95510 was recently merged. Is this PR ready to be merged?

I can be merged once the CI is green.

[AustinWise]

It is still failing with this error:

LINK : fatal error LNK1268: inconsistent option 'DEPENDENTLOADFLAG:0x800' specified with /USEPROFILE but not with /GENPROFILE

I'm guessing the PGO data is being built from the dotnet/runtime 8.0 branch, which does not have the DEPENDENTLOADFLAG. Someone at Microsoft would need to update the dnceng/internal/dotnet-optimization repo to build from the dotnet/runtime main branch to fix the problem.

Closing in favor of #95540 .
