* Stop trying to analyze class-hierarchies for dependently-scoped id-expressions;John McCall2009-12-024-125/+127
| | | | | | | | | | | | | there's nothing interesting we can say now that we're correctly not requiring the qualifier to name a known base class in dependent contexts. Require scope specifiers on member access expressions to name complete types if they're not dependent; delay lookup when they are dependent. Use more appropriate diagnostics when qualified implicit member access expressions find declarations from unrelated classes. llvm-svn: 90289

| | | | | | | | | | | | | | (clang/driver) command line arguments (including the source file). - The arguments are expected to include the source file. - The idea is that even though this is a somewhat odd API, its the form which many tools can most easily use (for example, by interposing with the compiler). Also, switch index-test's -ast-from-source to use this entry point, and provide a -arg command line argument which can be used to test that the command line arguments are handled correctly. llvm-svn: 90288

| | | | | | | | | | source locations with no common ancestor in the include stack, determine order by assuming memory buffers preceed files, and then that FileIDs are created in order. The later assumption is patently false, but this was already broken -- this situation is conceptually impossible, my feeling is we should fix SourceManager and friends to make it impossible in practice as well. However, we need to fix PR5662 and perhaps some other things involving memory buffers first. In the short term I'm pretty sure this is reliable. Chris, Argiris, is this going to break anything that wasn't already broken? llvm-svn: 90280

* Fix PR5391: support early clobber physical register def tied with a use (ewwww)Evan Cheng2009-12-013-4/+50
| | | | | | | | - A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber. - If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range. - Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature". llvm-svn: 90269

| | | | | | | | | | | | | | | implicit member access to a specific declaration, go ahead and create it as a DeclRefExpr or a MemberExpr (with implicit CXXThisExpr base) as appropriate. Otherwise, create an UnresolvedMemberExpr or DependentScopeMemberExpr with a null base expression. By representing implicit accesses directly in the AST, we get the ability to correctly delay the decision about whether it's actually an instance member access or not until resolution is complete. This permits us to correctly avoid diagnosing the 'problem' of 'MyType::foo()' where the relationship to the type isn't really known until instantiation. llvm-svn: 90266
