2010-11-19Several PPCallbacks take an SourceLocation + IdentifierInfo, ratherCraig Silverstein
than a Token that holds the same information all in one easy-to-use package. There's no technical reason to prefer the former -- the information comes from a Token originally -- and it's clumsier to use, so I've changed the code to use tokens everywhere.

-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a SourceLocation instead of a FullSourceLoc. -Reflect the changes to various interfaces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119730 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Calculate the value kind of an expression when it's created andJohn McCall
store it on the expression node. Also store an "object kind", which distinguishes ordinary "addressed" l-values (like variable references and pointer dereferences) and bitfield, @property, and vector-component l-values. Currently we're not using these for much, but I aim to switch pretty much everything calculating l-valueness over to them. For now they shouldn't necessarily be trusted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119685 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Don't warn for parentheses for the '&&' inside '||' for cases like:Argyrios Kyrtzidis
assert(a || b && "bad"); since this is safe. This way we avoid a big source of such warnings which in this case are practically useless. Note that we don't handle *all* cases where precedence wouldn't matter because of constants since this is a bit costly to check, and IMO clarifying precedence with parentheses is good for readability in general. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119533 91177308-0d34-0410-b5e6-96231b3b80d8
