What did you do?

Repeat step:

git clone https://gitee.com/u-language/u-language.git -b pgo2024-8-20

cd u-language
Set environment variable URoot to the current path
cd ucom

go test -run=ssss -bench="ComplierToCBuildMode2/多文件" -count=10 -pgo off > new.txt && sleep 20 && go test -run=ssss -bench="ComplierToCBuildMode2/多文件" -count=10 -pgo default.pgo > pgo.txt && benchstat new.txt pgo.txt

What did you see happen?

pgo does not cause performance degradation

What did you expect to see?

I tried tip,happen pgo cause worse performance on benchmark.
I tried 4b43b74 , no happen pgo cause worse performance on benchmark.
git bisect to 1b03568

That CL changed some inlining threshould. What function inlining changes at that CL, like it was not inlined before the CL and inlined after, or vice versa?

What type of benchmark is it? Is it a micro benchmark? How is the profile collected? Thanks.

What type of benchmark is it?

Benckmark come from open source code that I wrote while researching compilation principles.It reads the test data and processes it.

Is it a micro benchmark?

no,benchmark calls multiple functions,and according to the benchmark data, the time is in the microsecond level.

How is the profile collected?

run go test -run=ssss -bench=. -trimpath -benchtime=400ms -cpuprofile="default.pgo"

That CL changed some inlining threshould. What function inlining changes at that CL, like it was not inlined before the CL and inlined after, or vice versa?

I use D:\file\gofile\gogit\go1\bin\go build -gcflags=all="-d=pgoinline=1" -pgo default.pgo -trimpath and https://github.com/qiulaidongfeng/diffbench
