Bug ID: 22540
Summary: Gold fails when output file is lying on ZFS
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: vladimir at kondratyev dot su

gold-output.cc.patch
Some Copy-On-Write filesystems like recent ZFS does not support posix_fallocate
as it cannot provide guarantee that overwrites would never fail due to the
lack
of free space. In that case EINVAL is used to report that the underlying file
system does not support the operation (POSIX.1-2008) that breaks gold if output
file is lying on such a filesystem.
Fix gold with falling back to ftruncate(2) if posix_fallocate(2) returned
EINVAL but correct offset and len parameters was passed.
