           Summary: Assertion fails in SelectionDAGIsel.cpp
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW

When compiling simple .c file with llvm-gcc & enabled optimizations I have the
folowing assertion:

llc: /home/asl/proj/llvm/src/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp:2137:
void llvm::SelectionDAGLowering::visitInlineAsm(llvm::CallInst&): Assertion
`!Regs.Regs.empty() && "Couldn't allocate output reg!"' failed.

Please find attached files:

1. Source .c file
2. Compiled .bc file via "llvm-gcc -O1", everything is ok with optimizations
disabled.

Steps to reproduce:
1. Run llc -march=x86 round.bc
