Bug #: 55674
Summary: [4.8 Regression] >20% size increase of lto/pgo
binaries since r193747
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mar...@trippelsdorf.de
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45375#c144 onwards.
Binaries build with "-flto -fprofile-use" increased more than 20% in size
since revision 193747 went in.
libxul's size increased ~20%:
34MB before, 42MB now.
This also happens for simpler testcases, e.g tramp3d-v4.cpp (30% increase):
0.9MB before, 1.3M now.
Setting "--param hot-bb-count-ws-permille" to lower values doesn't help.
