| | | | | | | | | | | | | | | | | | | Make Signedness information pervasive throughout all types and values. There is no easy way to get around this. Because the GEP instruction can index through an arbitrarily complex value structure, it is necessary to keep track of signedness information throughout that structure. This change makes Signedness a full class, capable of representing Signedness in arbitrarily shaped types. The class is then used throughout llvm-upgrade to track signedness and differentiate between globals, locals, and functions based on their signedness. For PR1243: This patch also removes bogus warnings about renaming internal globals. It now only emits such warnings when renaming non-internal globals because they may affect linkage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35234 91177308-0d34-0410-b5e6-96231b3b80d8
