Daniel Dunbar 465f4c4867 In SourceManager::isBeforeInTranslationUnit, if we are trying to compare two 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?

Chris Lattner ed3b360290 pass the reason for failure up from MemoryBuffer and report it
in diagnostics when we fail to open a file.  This allows us to
report things like:

$ clang test.c -I.
test.c:2:10: fatal error: error opening file './foo.h': Permission denied
#include "foo.h"
         ^

Evan Cheng 732351f732 Fix PR5391: support early clobber physical register def tied with a use (ewwww)
- 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".

John McCall 2d74de9632 Rework how we support C++ implicit member accesses. If we can resolve an
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.

Fariborz Jahanian a6227fd896 (objc2 nonfragile-abi specific). If the translation unit includes an implementation
of a subclass (direct or indirect) of a weak_import root class, emit a weak reference 
for the root class's metaclass (should complete radar 6815425).

Douglas Gregor 6be3de3fa7 Funtion templates and function template specializations do not
override virtual functions. Also, eliminate a (now redundant) call to
AddOverriddenMethods.

2009-12-01 17:35:23 +00:00
Douglas Gregor 21920e3758 Move the checking of overridden virtual functions into the code path
common to both parsing and template instantiation, so that we'll find
overridden virtuals for member functions of class templates when they
are instantiated. 

Additionally, factor out the checking for pure virtual functions, so
that it will be executed both at parsing time and at template
instantiation time. 

These changes fix PR5656 (for real), although one more tweak
w.r.t. member function templates will be coming along shortly.

Jakob Stoklund Olesen defc47088a Move PHIElimination::isLiveOut method to LiveVariables.
We want LiveVariables clients to use methods rather than accessing the

Douglas Gregor e7488b904c Don't automatically assume that an id-expression refers to a
ValueDecl, because that isn't always the case in ill-formed
code. Diagnose a common mistake (forgetting to provide a template
argument list for a class template, PR5655) and dyn_cast so that we
handle the general problem of referring to a non-value declaration
gracefully.
