           Summary: Cannot Build llvm-gcc-4.2-2.8 on Solaris/x86
           Product: tools
           Version: 2.8
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-gcc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: spear at cse.lehigh.edu
                CC: llvmbugs at cs.uiuc.edu


I am unable to build llvm-gcc-4.2-2.8 on Solaris/x86.

I successfully built llvm-gcc-4.2-2.7 and llvm-2.7 on Solaris/x86.  I can also
build llvm-2.8 itself on Solaris/x86.  The break occurs only when moving from
the released llvm-gcc-4.2-2.7 to llvm-gcc-4.2-2.8

Platform:
uname -a == SunOS 5.10 Generic_142901-12 i86pc i386 i86pc

Toolchain:
gcc 4.5.1
binutils 2.20.1

Configure invocation:
../llvm-gcc-4.2-2.8.source/configure
--prefix=/proj/spear0/dtmc_x86/llvm-2.8-gcc --program-prefix=llvm-
--enable-llvm=/proj/spear0/dtmc_x86/llvm --enable-languages=c,c++
--enable-checking --with-gnu-as --with-as=/proj/spear0/binutils-2.20.1/bin/as
--with-gnu-ld --with-ld=/proj/spear0/binutils-2.20.1/bin/ld

The specific error occurs when building libgcc2.c.  I'm building using 'gmake'
(no -j flag).

Re-running gmake reproduces the error, and provides the following background
about gcc build progress:

The bug also occurs when using gcc 4.4.1 on Solaris/x86.  And even though the
exact error is "internal compiler error", which would imply a gcc bug, the fact
that both compilers can handle llvm-gcc-2.7-4.2 but not llvm-gcc-2.8-4.2
suggests that this has more to do with changes to llvm-gcc between the 2.7 and
2.8 releases.

Any advice would be greatly appreciated!
