Bug ID: 77821
Summary: C++ binary size increase or LTO not working?
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: tulipawn at gmail dot com
Target Milestone: ---
I've just revisited the compilation from issue #69082 and all's fine and good
but I can't seem to produce a similarly sized binary as in the past:
$ du -h ufo-gcc*
1716 ufo-gcc4.9-lto
2404 ufo-gcc4.9-nonlto
2384 ufo-gcc6-lto?
2348 ufo-gcc7-lto?
2340 ufo-gcc7-nonlto
In case it's simply about LTO not being used, the regular code is actually
getting smaller.
For 4.9 it was enough to put `-flto` among C(XX)FLAGS but now, also passing
those as LDFLAGS to the latter gcc's doesn't help. What gives?
