Bug #: 50639
Summary: -flto=jobserver broken on large LTO build
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: andi-gcc@firstfloor.org
On a -j8 Linux kernel LTO build with -flto=jobserver I always end up with
make[3]: *** read jobs pipe: No such file or directory. Stop.
make[3]: *** Waiting for unfinished jobs....
lto-wrapper: make returned 2 exit status
/usr/local/bin/ld-plugin: lto-wrapper failed
at the final link stage. The link is actually succeeding, but something
confuses jobserver
It works with -flto=8. The message comes from make.
It could be a regression, but it's hard to say because older much builds
usually ran into other problems.
