Extended Description

Same goes for global variables, it seems.

Bitcode showing the problem attached. It has two functions
with no name. They both get output by llvm-dis with the name
@"". Shouldn't this be a slot number? And llvm-as will not
read the resulting .ll, saying

llvm-as: noname.ll:5:21: use of undefined value '@'
@​f = alias void ()* @"" ; <void ()*> [#uses=0]

Please verify the global case works as well.

[llvmbot]

Thanks a lot. Unfortunately globals still don't parse.
Consider

@​0 = global i32 0

Then llvm-as says:

llvm-as: noname.ll:1:1: expected top-level entity
@​0 = global i32 0

Anonymous globals don't accept a name like that right now, this works fine though:

global i32 0
