Extended Description

There seems to be a bug in the .ll parser when referencing '@0'. The attached test case sends an error when running with llvm-as:

test.ll:2:17: forward reference and definition of global have different types

However, if you change the '@0' reference to a '@1' reference (thus referencing the next global variable) in the 'Try' variable, it works.

(And to make sure '@0' is the first unnamed global variable, changing '@0' to '@2' returns an error: "use of undefined value '@2'")

Verified, reduced testcase:

@​X = global i32* @​0
global i32 4
