            Bug ID: 22424
           Summary: Clang on 64-bit Windows defaults to trying to generate
                    32-bit code
           Product: clang
           Version: 3.5
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: LLVM Codegen

When you build Clang on 64-bit Windows using the 64-bit Microsoft C++ compiler,
the resulting version of Clang still defaults to generating 32-bit code,
leading to nonobvious link time error messages on a test compile of hello.c as
described in:


This can be worked around by supplying Clang with the -m64 command line option,
but the need for this isn't clear from the error message.

The preferred solution would be for the compiler to default to generating
64-bit code when on a 64-bit system or built with 64-bit Microsoft C++.
