[LLVMdev] llvm-gcc4.2-2.4 build failure in /gcc/java/lang.c

[Tielei Wang]

I did follow the README.LLVM.

I configure like:
../llvm-gcc4.2-2.4.source/configure --program-prefix=llvm- 
--enable-llvm=/home/wangtielei/TOOLS/llvm/llvm-obj/ 
--enable-language=c,c++ --disable-jit --disable-multilib

The error information is

../../llvm-gcc4.2-2.4.source/gcc/java/lang.c:378: error: 
‘force_align_functions_log’ undeclared (first use in this function)

But I do not understand why xgcc is invoked to compile java.c file.

Could you give me more hints?
