[LLVMdev] cross compiling to sparc with llvm

[Tarun Pondicherry]

Hi,

I'm trying to use llvm/clang to cross compile to sparcv9.  The following
works with a -march=sparc, but yields errors for sparcv9.  Are there some
other flags that need to be specified?

Thanks,
Tarun

> clang -m64 -emit-llvm test.c -c -o test.bc
> llc -march=sparcv9 test.bc -o hello.s
ExpandIntegerResult #0: 0x8a6c478: i64 = GlobalAddress<[4 x i8]* @.str> 0
[ORD=1] [ID=0]

Do not know how to expand the result of this operator!
