Douglas Gregor bb3d786213 Reinstate change to non-type template arguments of integral type, so
that we extend/truncate then correct the sign to convert the non-type
template argument to the template parameter's type. Previously, we
reported an error when the non-type template argument was out of
range; now we just warn.

Douglas Gregor 63eed63312 Warn when the conversion of an integral non-type template argument to
the type of its corresponding non-type template parameter changes the
value. Previously, we were diagnosing this as an error, which was
wrong. We give reasonably nice warnings like:

test/SemaTemplate/temp_arg_nontype.cpp💯10: warning: non-type template
      argument value '256' truncated to '0' for template parameter of type
      'unsigned char'

Douglas Gregor 210b590562 Teach the diagnostic engine to provide more detailed information about
how to handle a diagnostic during template argument deduction, which

deduction.

Douglas Gregor d6bc5e6bbc When a declaration of a function is missing an exception specification
that was present in a prior declaration, emit a warning rather than a
hard error (which we did before, and still do with mismatched
exception specifications). Moreover, provide a fix-it hint with the
throw() clause that should be added, e.g.,

t.C:10:7: warning: 'operator new' is missing exception specification
      'throw(std::bad_alloc)'
void *operator new(unsigned long sz)
      ^
                                     throw(std::bad_alloc)

As part of this, disable the warning when we're missing an exception
specification on operator new, operator new[], operator delete, or
operator delete[] when exceptions are turned off (-fno-exceptions).

Fixes PR5957.

Douglas Gregor f9f54eab43 Make sure to properly track the anonymous namespace that lives inside
each namespace, even when the outer namespace has multiple

exclusive, saving a pointer per NamespaceDecl. Fixes PR6620.

Douglas Gregor 4165bd6772 Implement computation of the final overriders for each virtual
function within a class hierarchy (C++ [class.virtual]p2).

We use the final-overrider computation to determine when a particular
class is ill-formed because it has multiple final overriders for a
given virtual function (e.g., because two virtual functions override
the same virtual function in the same virtual base class). Fixes
PR5973.

We also use the final-overrider computation to determine which virtual
member functions are pure when determining whether a class is
abstract or diagnosing the improper use of an abstract class. The
prior approach to determining whether there were any pure virtual
functions in a class didn't cope with virtual base class subobjects
properly, and could not easily be fixed to deal with the oddities of
subobject hiding. Fixes PR6631.

Douglas Gregor 8579531684 Introduce the notion of a single "delayed" diagnostic into the
Diagnostic subsystem, which is used in the rare case where we find a
serious problem (i.e., an inconsistency in the file system) while
we're busy formatting another diagnostic. In this case, the delayed
diagnostic will be emitted after we're done with the other
diagnostic. This is only to be used for fatal conditions detected at
very inconvenient times, where we can neither stop the current
diagnostic in flight nor can we suppress the second error.

2010-03-19 21:58:23 +00:00
Douglas Gregor aae9224e49 Implement serialization and lazy deserialization of the preprocessing
record (which includes all macro instantiations and definitions). As
with all lay deserialization, this introduces a new external source
(here, an external preprocessing record source) that loads all of the
preprocessed entities prior to iterating over the entities.

The preprocessing record is an optional part of the precompiled header
that is disabled by default (enabled with
-detailed-preprocessing-record). When the preprocessor given to the
PCH writer has a preprocessing record, that record is written into the
PCH file. When the PCH reader is given a PCH file that contains a
preprocessing record, it will be lazily loaded (which, effectively,
implicitly adds -detailed-preprocessing-record). This is the first
case where we have sections of the precompiled header that are
added/removed based on a compilation flag, which is
unfortunate. However, this data consumes ~550k in the PCH file for
Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering
this detailed preprocessing information, so it's too expensive to turn
on by default. In the future, we should investigate a better encoding
of this information.

John McCall a0296f7987 Remember the "found declaration" for an overload candidate, which is the
entity (if applicable) which was actually looked up.  If a candidate was found
via a using declaration, this is the UsingShadowDecl;  otherwise, if
the candidate is template specialization, this is the template;  otherwise,
this is the function.

The point of this exercise is that "found declarations" are the entities
we do access control for, not their underlying declarations.  Broadly speaking,
this patch fixes access control for using declarations.

There is a *lot* of redundant code calling into the overload-resolution APIs;
we really ought to clean that up.

llvm-svn: 98837
2010-03-18 18:04:21 +00:00
Douglas Gregor 065f8d11ca Introduce the notion of a "preprocessing record", which keeps track of
the macro definitions and macro instantiations that are found
during preprocessing. Preprocessing records are *not* generated by
default; rather, we provide a PPCallbacks subclass that hooks into the
existing callback mechanism to record this activity.

The only client of preprocessing records is CIndex, which keeps track
of macro definitions and instantations so that they can be exposed via
cursors. At present, only token annotation uses these facilities, and
only for macro instantiations; both will change in the near
future. However, with this change, token annotation properly annotates
macro instantiations that do not produce any tokens and instantiations
of macros that are later undef'd, improving our consistency.

Preprocessing directives that are not macro definitions are still
handled by clang_annotateTokens() via re-lexing, so that we don't have
to track every preprocessing directive in the preprocessing record.

Performance impact of preprocessing records is still TBD, although it
is limited to CIndex and therefore out of the path of the main compiler.

Douglas Gregor 5712ebced0 Fix header-search problems with precompiled headers, where the
presence or absence of header map arguments when using the precompiled
header would cause Clang to get confused about which headers had
already been included/imported, along with their controlling
macros. The fundamental problem is that the serialization of the
header search information was relying on the UIDs of FileEntry objects
at PCH generation time and PCH load time to be equivalent, which
effectively means that we had to probe the same files in the same
order. Differing header map arguments caused an extra FileEntry
lookup, but it's easy to imagine other minor command-line arguments
triggering this problem.

Header-search information is now encoded along with the
source-location entry for a file, so that we register information
about a file's properties as a header at the same time we create the
FileEntry for that file.

Fixes <rdar://problem/7743243>.

Douglas Gregor 7bda4b8310 Introduce optional "Invalid" parameters to routines that invoke the
SourceManager's getBuffer() and, therefore, could fail, along with
Preprocessor::getSpelling(). Use the Invalid parameters in the literal
parsers (string, floating point, integral, character) to make them
robust against errors that stem from, e.g., PCH files that are not
consistent with the underlying file system.

I still need to audit every use caller to all of these routines, to
determine which ones need specific handling of error conditions.

Douglas Gregor 802b77601e Introduce a new BufferResult class to act as the return type of
SourceManager's getBuffer() (and similar) operations. This abstract
can be used to force callers to cope with errors in getBuffer(), such
as missing files and changed files. Fix a bunch of callers to use the
new interface.

Add some very basic checks for file consistency (file size,
modification time) into ContentCache::getBuffer(), although these
checks don't help much until we've updated the main callers (e.g.,
SourceManager::getSpelling()).

Destroy methods at the same time, to ensure that the correct teardown was
being done.
