            Bug ID: 25305
           Summary: Clang-cl generates a call to an undefined symbol
                    __udivti3
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: LLVM Codegen

Build with: clang-cl main.c

While attempting to build a (very) old version of libtomcrypt with Clang-cl
(64-bit r250698), it appears a call to an undefined function is being
generated:

main-ff9827.obj : error LNK2019: unresolved external symbol __udivti3
referenced in function main

I've attached a minimal reproduce case. This appears to be due to the
"__attribute__((mode(TI)))" on the typedef.
