Subject: [PATCH] Make LTO tests that require recent binutils UNSUPPORTED with older ones (PR lto/86004)
Date: Tue, 11 Dec 2018 07:31:00 -0000	[thread overview]
Message-ID: <20181211073122.GL12380@tucnak> (raw)

Hi!

As mentioned in the PR, older binutils (like 2.25) complain on these tests
when using -r that:
plugin needed to handle lto object
The following patch introduces an effective target and guards those tests on
a linker with this issue fixed.

Regtested on x86_64-linux and i686-linux, plus regtested on x86_64-linux
with 2.25 binutils, where the patch converts all those FAILs into
UNSUPPORTEDs.

Ok for trunk?
