[LLVMdev] Odd problem with command line options

[Richard Pennington]

I'm linking a program (my ellsif driver) that basically brings in most 
of the LLVM stuff: bitcode reading, optimizations, linking, and target 
code generation.

All of a sudden, I'm getting the following when I run:
[~/elsa/ellsif] dev% ./ellsif -v test/ofmt.i test/sieve.i -time-actions -O5
<premain>: CommandLine Error: Argument 'machine-licm' defined more than 
once!
ellsif: CommandLine Error: Argument 'machine-licm' defined more than once!

It seems like the constructor for this argument is being run twice. 
ellsif works as expected, but I'd like to figure out what's going wrong.

The link command is:
g++ -o ellsif ellsif.o elsa.o -g -Wall ../elsa/libelsa.a 
../elkhound/libelkhound.a ../ast/libast.a ../smbase/libsmbase.a 
-L/home/rich/llvm-install/lib  -lpthread -ldl -lm -lelf  -lLLVMLinker 
-lLLVMArchive -lLLVMipo -lLLVMInstrumentation -lLLVMBitWriter 
-lLLVMBitReader /home/rich/llvm-install/lib/LLVMMSIL.o 
/home/rich/llvm-install/lib/LLVMCBackend.o 
/home/rich/llvm-install/lib/LLVMCellSPU.o 
/home/rich/llvm-install/lib/LLVMMips.o

/home/rich/llvm-install/lib/LLVMAlpha.o 
/home/rich/llvm-install/lib/LLVMPowerPC.o 
/home/rich/llvm-install/lib/LLVMSparc.o 
/home/rich/llvm-install/lib/LLVMX86.o -lLLVMSelectionDAG -lLLVMCodeGen 
-lLLVMScalarOpts -lLLVMTransformUtils -lLLVMipa -lLLVMAnalysis 
-lLLVMTarget -lLLVMCore -lLLVMSupport -lLLVMSystem

Does this sort of thing ring a bell with anyone?
