http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48301

           Summary: Xcode 4.0's llvm-gcc can't bootstrap gcc 4.6.0 or
                    trunk
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: howarth@nitro.med.uc.edu


While Xcode 4.0's clang can bootstrap FSF gcc trunk and 4.6.0, the llvm-gcc
compiler can not. The bootstrap fails as...

While this is likely a bug in llvm-gcc, we should attempt to analyze it and
file the appropriate radar bug reports against llvm-gcc in case Apple switches
to llvm-gcc as the system compiler in the future.

Same issue exists with llvm-gcc from llvm 2.9 svn.

So llvm miscompiles cc1.  Not a GCC bug.

If there is an easy work around in gcc to avoid the problem, we could entertain
that, but, generally, I'd be more interested in clang failures going forward. 
llvm-gcc is old and getting older every day.  The dragon egg bits are newer and
more compelling.

This issue has been fixed in Apple's llvm-gcc at revision 128619. It is unclear
if this fix will make it into llvm.org's llvm-gcc-4.2 2.9 release (which is
slated to be the final one with llvm-gcc). The patch...

http://llvm.org/bugs/show_bug.cgi?id=9571#c13

can be manually applied if it isn't. I've confirmed that this fixes the
bootstraps of both 4.4.5 and 4.6.0.

FYI, this issue appears to be fixed in the llvm-gcc-4.2 of Xcode 4.3. Of course
that only helps Xcode users on Lion or later.
