An oddity of the .ll syntax is that the "@var = " in @var = global i32 42 is optional. Writing just global i32 42 is equivalent to @0 = global i32 42 This means that there is a pretty big First set at the top level. The current implementation maintains it manually. I was trying to refactor it, but then started wondering why keep it a all. I personally find the above syntax confusing. It looks like something is missing. This patch removes the feature and simplifies the parser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@269096 91177308-0d34-0410-b5e6-96231b3b80d8
