Hi Kai !

LLVM does generates incompatible with MS tool(case jmp table 
lable , seh lable
etc)

the problem is 'set directive'

do patch llvm, HasSetDirective from true to false.

<llvm/lib/MC/MCAsmInfo.cpp>

   GPRel64Directive = 0;
   GPRel32Directive = 0;
   GlobalDirective = "\t.globl\t";
   HasSetDirective = false;//true;      <---- this, line number 74,
   HasAggressiveSymbolFolding = true;
   COMMDirectiveAlignmentIsInBytes = true;
   LCOMMDirectiveAlignmentType = LCOMM::NoAlignment;



I used <git clone http://llvm.org/git/llvm.git llvm> version.

but final link error genarated.

which version is required for avoiding this phobos link problem?
