Mine.  Moving down the code in function.c that's under the comment:
         /* If a named return value dumped decl_return to memory, then
            we may need to re-do the PROMOTE_MODE signed/unsigned
            extension.  */
so that the test:
         else if (GET_MODE (real_decl_rtl) != GET_MODE (decl_rtl))
appears after the blocks that deal with PARALLELs and CONCATs fixes it for me,
without any regressions on x86* regstraps.

Could you please confirm it fixes bootstrap on alpha?  TIA,

Yes, the patch, based on the above instructions, passes the bootstrap. I'm
currently in the regression tests, but I don't expect any surprises there.

            Bug ID: 67890
           Summary: search paths for user shared libraries not respected
           Product: gcc
           Version: 5.1.1
            Status: UNCONFIRMED

Hi

The following g++ command fails to link the target shared library. The command
explicitly states to the linker to use shared libraries into /usr/local/lib
while it picks up those from /usr/lib64

--- Comment #3 from Craig Rodrigues <rodrigc at gcc dot gnu.org> ---
This is for cross-compiling the FreeBSD base system with GCC.
The FreeBSD base system has libc++, which was recently upgraded to clang 3.7.0.

Cross-compiling FreeBSD base system with GCC worked before,
with an older version of libc++.

Discussion on the llvm cfe-dev mailing list seems to point to this
being a bug in GCC, hence I filed this bug.
