            Bug ID: 38866
           Summary: WebAssembly- assertion failure with alias for function
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: llc
          Assignee: unassignedbugs at nondot.org
          Reporter: dfordivam at gmail.com
                CC: llvm-bugs at lists.llvm.org

The alias in following code causes the below mentioned assertion with
webassembly target. It works fine with x86.

I guess this is because the alias Symbol is marked as 'isData' instead of
'isFunction'


llc: /home/divam/repos/llvm/lib/MC/WasmObjectWriter.cpp:1323: virtual uint64_t
{anonymous}::WasmObjectWriter::writeObject(llvm::MCAssembler&, const
llvm::MCAsmLayout&): Assertion `DataLocations.count(ResolvedSym) > 0' failed.

target datalayout = "e-m:e-p:32:32-i64:64-n32:64-S128"

{
c9YQ:
  %ln9YZ = ptrtoint i8* @MainCapability to i32
  %ln9Z0 = add i32 %ln9YZ, 808
  ret void
}
@MainCapability = external global i8
