[LLVMdev] Re: Notes on the release notes for the fifth public release of LLVM

[Jeff Cohen]

Well, Henrik has a point.  As of now, the only thing LLVM is good for
when built with VS is the JIT engine, and then only if you're willing to
write your own front end--or be satisfied computing fibonacci numbers :)
That doesn't make it useless, of course, as Morten will testify, but
the market for this level of functionality can't be big.  I do plan on
creating projects to build llc and lli (perhaps in time for the next
release) and that would help a lot, but without the C/C++ front end...

Yuck... what about the C runtime?  I can compile a C/C++ program on Unix
and copy the bytecode file over to Windows and then (eventually)
generate assembler that NASM can turn into a binary.  But what to link
against?  Microsoft's C runtime library?  C++ runtime is even worse, as
name mangling is completely different.  Then there's __cdecl vs
__fastcall.  VC++ exception handling is implemented in an utterly
different fashion than g++ also.  Any words of assurance :)
