*I am sorry for making you confused when I presented my problem.*
*1. My steps for the test suit building:*
(1) cd /home/qali/Src;  *           // This is my source directory for all
application programs*
(2) tar xzf llvm-2.8.tgz; *           // now, the top directory of source
tree is /home/qali/llvm-2.8*
(3) cd llvm-2.8/projects
(4) svn co http://llvm.org/svn/llvm-project/test-suite/trunk test-suite* //
now I check out the test suite into /home/qali/llvm-2.8/projects*
(5) cd /home/qali/install;*        // This is my Install directory for all
applications*
(6) tar xjf llvm-gcc4.2-2.8-x86_64-linux.tar.bz2*      //Now, the binary
file for llvm-gcc is in /bin, since what I downloaded was the binary version
*
(7) cd /home/qali/Build;      mkdir llvm-2.8;   cd llvm-2.8*;         **//
Now, it is in my top directory for building llvm: /home/qali/Build/llvm-2.8*
(8) /home/qali/Src/llvm-2.8/configure --prefix=/home/qali/install/llvm-2.8
--enable-debug-runtime  --disable-optimized --enable-debug-symbols
--enable-assertions   --with-llvmgccdir=
/home/qali/install/llvm-gcc4.2-2.8-x86_64-linux
(9) make
(10) /home/qali/Src/llvm-2.8/configure --prefix=/home/qali/install/llvm-2.8
--enable-debug-runtime  --disable-optimized --enable-debug-symbols
--enable-assertions
--with-llvmgccdir=/home/qali/install/llvm-gcc4.2-2.8-x86_64-linux
         * // reconfigure process*
(11) grep EMITIR *
Here, I get no results. It seems LLVMCC_EMITIR_FLAG was not set during my
configuration.
My linux is Fedora Core 13, cpu is intel i3, and host gcc is 4.4.5.
*

2. After the reconfigure process, I have search LLVM in config.log, and all
the results are below:
[qali at qali llvm-2.8-ori]$ grep "^LLVM" config.log
