Extended Description

A version of Olden benchmark perimeter when compiled with llvm-gcc-4.2 with llvm-2.3 aborts with the following error

llvm/llvm-2.3/lib/CodeGen/LiveVariables.cpp:143: void llvm::LiveVariables::HandleVirtRegUse(unsigned int, llvm::MachineBasicBlock*, llvm::MachineInstr*): Assertion `MBB != MRI->getVRegDef(reg)->getParent() && "Should have kill for defblock!"' failed.

Command-Line used to compile the benchmark

llvm-gcc -m64 -O3 -lm -DPLAIN -DSS_PLAIN -DI_TIME -DI_SYS_TIME -DULTRIX -o test *.c

Same benchmark was compiling successfully with llvm-2.2.

I am using gcc-4.2.0 on X86-64 machine with Suse linux.

I have attached the c source for perusal

Works for me with mainline on darwin/x86-64. Please verify.
