[LLVMdev] internal compiler error when compiling llvm-gcc-4.2-2.9

[Hongxu Chen]

Hi everyone,

   Recently I tried to compile llvm-gcc-4.2-2.9 on a 64bit ubuntu12.04
machine. And I was using the settings below,

    export C_INCLUDE_PATH=/usr/include/x86_64-linux-gnu
    export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu
    ../llvm-gcc-4.2-2.9.source/configure --enable-optimized 
--program-prefix=llvm- --enable-checking
--enable-llvm=${HOME}/moonbox/llvm-obj/Debug+Asserts --disable-bootstrap --   
enable-languages=c,c++
    make CXX=/usr/bin/clang++

Here `${HOME}/moonbox/llvm-obj/Debug+Asserts' contains the built llvm
lib/bin, I have also added the include directory into this path for
convenience. But then I came across this error message:

    /home/hongxuchen/moonbox/llvm-gcc-obj/./gcc/xgcc -shared-libgcc

And I don't know what happens. However I remembered I built this version of
llvm-gcc successfully with similar configuration and the major difference
seems this time I build llvm with --disable-optimized. I have also tried to
build llvm-gcc with `make CXX=/usr/bin/g++' and `--disable-optimized', but
with the same result.

Please see the attached log files if you are interested:-)( stderr.log
<http://llvm.1065342.n5.nabble.com/file/n56010/stderr.log>   and  stdout.log
<http://llvm.1065342.n5.nabble.com/file/n56010/stdout.log>  )

Thanks in advance.
