~/llvm-git/llvm/utils/GenLibDeps.pl -flat -why ../../Release/lib "nm -p" >out

lli is 9.7M on x86-64, some libs are linked in that shouldn't, such as
AsmParser.

llvm-config --libs x86codegen says:
-lLLVMX86CodeGen -lLLVMX86Info -lLLVMSelectionDAG -lLLVMAsmPrinter -lLLVMMC
-lLLVMCodeGen -lLLVMScalarOpts -lLLVMTransformUtils -lLLVMipa -lLLVMAnalysis
-lLLVMTarget -lLLVMCore -lLLVMSupport -lLLVMSystem

Looking at the -why output from GenDepLibs.pl I see:
libLLVMSelectionDAG.a:
 libLLVMAsmPrinter.a
  _ZN4llvm11DwarfWriter15RecordRegionEndEPNS_14GlobalVariableE
  _ZN4llvm11DwarfWriter16RecordSourceLineEjjNS_13DICompileUnitE
  _ZN4llvm11DwarfWriter17RecordRegionStartEPNS_14GlobalVariableE
  _ZN4llvm11DwarfWriter18RecordInlinedFnEndENS_12DISubprogramE
_ZN4llvm11DwarfWriter19RecordVariableScopeERNS_10DIVariableEPKNS_12MachineInstrE
 
_ZN4llvm11DwarfWriter20RecordInlinedFnStartENS_12DISubprogramENS_13DICompileUnitEjj
  _ZN4llvm11DwarfWriter2IDE
  _ZNK4llvm11DwarfWriter20ShouldEmitDwarfDebugEv

See attached full -why output.
