[LLVMdev] linker errors when trying to link llvm-gcc

[Anatoly Yakovenko]

I am trying to build a cross compiler for arm on linux, here is how i
have configured it

cd llvm-gcc-4.2-2.7.source-objtree

../llvm-gcc-4.2-2.7.source/configure
--enable-llvm=/home/anatolyy/qctp406/pakman/depot/users/anatolyy/proto/crosscompiler/llvm-2.7
--enable-multilib --enable-target-optspace --enable-interwork
--with-newlib --with-gnu-as --with-gnu-ld --enable-languages=c,c++
--target=arm-elf
--prefix=/home/anatolyy/qctp406/pakman/depot/users/anatolyy/proto/crosscompiler/arm-elf

i've been able to build vanila gcc 4.2 to 4.5 using this configuration
for arm, but not llvm.  So i deleted my tree and tried again and i got
these errors now:


../../llvm-gcc-4.2-2.7.source/gcc/config/arm/lib1funcs.asm: Assembler messages:
../../llvm-gcc-4.2-2.7.source/gcc/config/arm/lib1funcs.asm:1004:
Error: backward ref to unknown label "8:"


Thanks,
Anatoly
