Bug ID: 70328
Summary: default generated destructors cause 'inlining failed'
warnings.
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: carlo at gcc dot gnu.org
Target Milestone: ---
I'm getting a warning for many many classes along of the lines:
../../../speech/src/xml/catalog_test.cpp:73:7: warning: inlining failed in call
to ‘Product::~Product() noexcept (true)’: call is unlikely and code size would
grow [-Winline]
while there isn't a ~Product() declared at all by me (it's compiler generated).
If I add a '~Product() = default', the warning stays. If I add instead
'~Product() noexcept { }' the warning goes away.
I don't have a small test case yet because any attempts to create that failed
so far. First I'd like to hear if there is consensus on that there is something
fishy about this warning.
