- Subject: [PATCH] Make -flto=jobserver parallel again.
Hi.
As I did quite some changes in the LTO logic, revision
r274232 dropped default value of parallel back to 0.
Doing that, I forgot to set it to 1 at the places where
jobserver is detected.
I tested that LTO bootstrap is parallel again.
Ready to be installed?
Thanks,
Martin

* lto-wrapper.c (run_gcc): When setting jobserver
set also parallel to 1. This was done so before r273908.
