llvm dev - Apr 2007 - [LLVMdev] LLVM command options in Visual Studio

Thank you for your kind explanation.
I did it as you mentioned.
That is, I set '-march=x86 hello.bc' in the Command Arguments.
(I also set my compiled LLC, i.e., LLVM_ROOT_DIR\win32\debug\llc.exe, in the
property name Command.)

But, when I made a breakpoint in main( ) of llc.cpp and then started to debug I
found the 'InputFilename'(llc.cpp:176) is shown like {???}. Therefore it
didn't proceed further, spitting out 'bytecode didn't read
correctly.'
(Of course, my bytecode was trasferred to my computer as binary.)

Would you mind telling me what seems my problem?
Thank you so much.

You didn't need to do this.  The default of $(TargetPath) is correct.

Therefore it didn't proceed
You need to expand the object into its component members by clicking on 
the +.  You'll see: 
'llvm::cl::opt_storage<std::basic_string<char,std::char_traits<char>,std::allocator<char>
 >,0,1>    {"hello.bc"}' as the second field of the object.

Can't help you here.  I have no idea why your hello.bc is corrupted.  
All I can suggest is to step through the bytecode reader and see why 
it's unhappy (there should be a reason following "bytecode didn't
read
correctly").  You might also try specifying hello.bc with a full path, 
or setting the Working Directory to where the file resides.
