Hi,
LTO bootstrap has been broken for more than a month:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48148
In the meantime, we have more LTO bootstrap regressions:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48652
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48671
Do we have a plan to fix LTO bootstrap
Thanks.

I'm about to submit a fix for the .Ldebug_info0 failure.

I was LTO bootstrapping yesterday just fine. You're talking about
bootstrap-profiled.
Ciao,

Not clear at all, a regular LTO bootstrap had failed on cc1 for days here.

Hmpf. Strange. I've bootstrapped with all languages except Ada
yesterday, with gold as plugin-ld.
Ciao,
Michael.

GNU ld (with plugins) for me, but --enable-checking=yes,rtl. Maybe H.J. had
e.g. --enable-checking=release. In any case, something is brittle ATM.

Not really unexpected - LTO testing coverage is pretty low unless we force
everyone to do LTO bootstraps (and then LTO bootstrap is slow because
of the redundant linking for the checksums and re-optimizing libbackend.a
all the time).

I have been doing LTO bootstrap and reporting failures. The current

This is FDO problem, not LTO problem and should be fixed now.

I just fixed at least the inliner profiledbootstrap ICE. I will try to profiledltobootstrap next.
