[LLVMdev] Windows/Visual Studio 2010 warnings (WARNINGS!)

[Mikael Lyngvig]

Hi,

I stumbled across three warnings in LLVM when building with MS Visual 
Studio 2010.  It has been my experience that different compilers detect 
different things, so I thought I'd pass them on to you (in case your 
compiler does not warn about these things):

warning C4805: '==' : unsafe mix of type 'bool' and type 'unsigned int' 
in operation    lib\Transforms\IPO\ExtractGV.cpp            58        
     1    LLVMipo
warning C4805: '==' : unsafe mix of type 'bool' and type 'unsigned int' 
in operation    lib\Transforms\IPO\ExtractGV.cpp            68        
     1    LLVMipo
warning C4065: switch statement contains 'default' but no 'case' 
labels                        lib\Target\X86\X86GenRegisterInfo.inc    
4360       1    LLVMX86CodeGen

The two first seem worth some attention, the latter just seems slightly 
bizarre.


Cheers,
Mikael

P.S. I was thinking you perhaps could make a blinking button labeled 
"Windows" on the front page of http://www.llvm.org, which when clicked 
guided people through the steps needed to build on Windows?  Just a 
joke, but I do feel slightly daft.  It's all in the docs.  It is just 
that there are so many docs and so little expectation of native Windows 
support given the fact that you only provide MINGW32 executables.
