These regressions are due to pr216154 and do not show when gcc is configured
with --enable-checking=release.

So, is this compile time failure or runtime failure (or both for two tests)?

If gcc is configured without --enable-checking=release (default checking for
trunk), it is a compile problem. If gcc is configured with
--enable-checking=release, it is a runtime problem.

You can run the testsuite with "-m32 -fpic" on linux using:
make -j 4 -k check RUNTESTFLAGS="--target_board=unix/-m32/-fpic"

It's only in trunk (the backport I made was in Linaro 4.9 branch). For FSF
branches check with the maintainers and/or ping Tony, I don't mind doing it,
but it's maybe better if done by the patch owner.

So far it seems the issue unlikely caused by PIC-related changes in i686 - test
passes with -fno-devirtualize.

It only happens when --param ipa-cp-eval-threshold is used.

-fdevirtualize-speculatively doesn't work well with IPA-CP cloning
under 32-bit PIC.

--- Comment #18 from H.J. Lu <hjl.tools at gmail dot com> ---
Igor, Kirill, I confirmed r216154 is the cause of this
bug. You can checkout both r216153 and r216154. You build
2 compilers and compare results. You can build a cross
compiler with
.../gcc/configure --enable-languages=c,c++ --disable-bootstrap
--target=x86_64-apple-darwin
you will see ICE. If you build the native Linux compiler, you
will see run-time failure. The difference between good and
bad assembly code is

Indeed. expand_thunk creates this when
targetm.asm_out.can_output_mi_thunk returns false. Therefore a change
in the back-end can cause this difference. The back-end changes might
be OK, we have had a bug like this in IPA before.
Do I understand correctly that this bug is an ICE with checking
compiler and miscompilation with release-checking one?

--- Comment #25 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I proposed a fix on the mailing list:
https://gcc.gnu.org/ml/gcc-patches/2014-11/msg02832.html
If it gets accepted, please feel free to add the testcase(s). I only
checked using a darwin cross compiler and so could not easily verify
the test would fail without the patch when run as part of the
testsuite. Ditto if you know what is the correct way to add a
testcase that should only be run on x86 -m32 with -fpic. Thanks.

Thanks for the confirmation, now we just need Honza to approve at
least the first patch if not both. I will ping them on mailing list
soon.

Fixed (and as I wrote in comment #25, feel free to add testcases if
you know how and have environment in which you can verify they would
fail without the fix when run by the testsuite).

On darwin, it's already covered by g++.dg/ipa/pr61160-1.C
For linux, I cannot don't know and cannot test.

It isn't fixed on Linux.

Without r218265, the new testcase fails on Linux.
