* Address review feedback on r221933.Nico Weber2014-12-271-3/+4
| | | | | | | | | | | | Remove ObjCMethodList::Count, instead store a "has more than one decl" bit in the low bit of the ObjCMethodDecl pointer, using a PointerIntPair. Most of this patch is replacing ".Method" with ".getMethod()". No intended behavior change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@224876 91177308-0d34-0410-b5e6-96231b3b80d8

* Hide the concept of diagnostic levels from lex, parse and semaAlp Toker2014-06-151-13/+5
| | | | | | | | | | | | | | | | The compilation pipeline doesn't actually need to know about the high-level concept of diagnostic mappings, and hiding the final computed level presents several simplifications and other potential benefits. The only exceptions are opportunistic checks to see whether expensive code paths can be avoided for diagnostics that are guaranteed to be ignored at a certain SourceLocation. This commit formalizes that invariant by introducing and using DiagnosticsEngine::isIgnored() in place of individual level checks throughout lex, parse and sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211005 91177308-0d34-0410-b5e6-96231b3b80d8
