Hi,
we have scan-tree-dump that scans in test.c.* files. But when we run
lto1 for the offloaded region, we produce test.o.* files instead. In
the test-case above, I work around that by using 'dg-final { file copy
}'. What is a good way to get rid of this workaround ?
Add scan-o-tree-dump ?
Or make the "slp1" field smarter, and allow f.i. "o.slp1" ?
Thanks,
