Bug #: 54966
Summary: Does LTO requires a larger inline-unit-growth?
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: vincenzo.innocente@cern.ch
experimenting with our large application I'm under the impression that in order
to get the same level of inlining with lto I need to increase
--param inline-unit-growth to at least 50 (my understanding is that the default
is 30).
Is this something expected / already observed?
Do you have any plan to retune heuristics for lto?
It is quite critical with some meta-template "expression expansion" code
