Bug ID: 95913
Summary: Capturing lambdas inlining behavior changed in GCC
10.x
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: leonid.satanovsky at gmail dot com
Target Milestone: ---
Greetings!
There is a bug suspicion, and I wanted to report it by the following example.
https://godbolt.org/z/m6g3Ug
GCCs 9.x and older inline capturing lambdas for the case in example even on -O1
GCC 10.1 always inlines only on -O3. On -O2 inlines it only if capturing lambda
is called < 3 times in a row.
Best regards, Leonid.
