2009-10-13Unify our diagnostic printing for errors of the form, "we didn't likeDouglas Gregor
what we found when we looked into <blah>", where <blah> is a DeclContext*. We can now format DeclContext*'s in nice ways, e.g., "namespace N", "the global namespace", "'class Foo'". This is part of PR3990, but we're not quite there yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84028 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-17Initial implementation of a code-completion interface in Clang. InDouglas Gregor
essence, code completion is triggered by a magic "code completion" token produced by the lexer [*], which the parser recognizes at certain points in the grammar. The parser then calls into the Action object with the appropriate CodeCompletionXXX action. Sema implements the CodeCompletionXXX callbacks by performing minimal translation, then forwarding them to a CodeCompletionConsumer subclass, which uses the results of semantic analysis to provide code-completion results. At present, only a single, "printing" code completion consumer is available, for regression testing and debugging. However, the design is meant to permit other code-completion consumers. This initial commit contains two code-completion actions: one for member access, e.g., "x." or "p->", and one for nested-name-specifiers, e.g., "std::". More code-completion actions will follow, along with improved gathering of code-completion results for the various contexts. [*] In the current -code-completion-dump testing/debugging mode, the file is truncated at the completion point and EOF is translated into "code completion". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82166 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-26Improve diagnostics and recovery when the nested-name-specifier of aDouglas Gregor
qualified name does not actually refer into a class/class template/class template partial specialization. Improve printing of nested-name-specifiers to eliminate redudant qualifiers. Also, make it possible to output a nested-name-specifier through a DiagnosticBuilder, although there are relatively few places that will use this leeway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80056 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-14Update LLVM.Douglas Gregor
Implement support for C++ Substitution Failure Is Not An Error (SFINAE), which says that errors that occur during template argument deduction do *not* produce diagnostics and do not necessarily make a program ill-formed. Instead, template argument deduction silently fails. This is currently implemented for template argument deduction during matching of class template partial specializations, although the mechanism will also apply to template argument deduction for function templates. The scheme is simple: - If we are in a template argument deduction context, any diagnostic that is considered a SFINAE error (or warning) will be suppressed. The error will be propagated up the call stack via the normal means. - By default, all warnings and errors are SFINAE errors. Add the NoSFINAE class to a diagnostic in the .td file to make it a hard error (e.g., for access-control violations). Note that, to make this fully work, every place in Sema that emits an error *and then immediately recovers* will need to check Sema::isSFINAEContext() to determine whether it must immediately return an error rather than recovering. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73332 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-02when creating custom warning diagnostics, do not attempt to mapChris Lattner
them with -Werror. Custom diags cannot be mapped, and this makes -Werror cause a determinstic crash for the checker and other clients of the custom diagnostics machinery. rdar://6816191 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70639 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-16move handling of -pedantic and -pedantic-errors into Diagnostics,Chris Lattner

2009-04-15Make diagnostic class explicit in the diag record instead ofChris Lattner
implicit from its parenting. Now that diag mapping is explicit, eliminate the fatal and extwarn classes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69177 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-15Tblgen now passes the default mapping explicitly, instead of having it Chris Lattner
be tied to the diag class. This requires an LLVM tree update. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69175 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-15Rejigger how -pedantic and -pedantic-errors work and their interactionChris Lattner
with other diagnostic mapping. In the new scheme, -Wfoo or -Wno-foo or -Werror=foo all override the -pedantic options, and __extension__ robustly silences all extension diagnostics in their scope. An added bonus of this change is that MAP_DEFAULT goes away, meaning that per-diagnostic mapping information can now be stored in 2 bits, doubling the density of the Diagnostic::DiagMapping array. This also substantially simplifies Diagnostic::getDiagnosticLevel. OTOH, this temporarily introduces some "macro intensive" code in Diagnostic.cpp. This will be addressed in a later patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69154 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-10Add a notion of "post-diagnostic hooks", which are callbacks attachedDouglas Gregor
to a diagnostic that will be invoked after the diagnostic (if it is not suppressed). The hooks are allowed to produce additional diagnostics (typically notes) that provide more information. We should be able to use this to help diagnostic clients link notes back to the diagnostic they clarify. Comments welcome; I'll write up documentation and convert other clients (e.g., overload resolution failures) if there are no screams of protest. As the first client of post-diagnostic hooks, we now produce a template instantiation backtrace when a failure occurs during template instantiation. There's still more work to do to make this output pretty, if that's even possible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66557 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19replace a dirty hack with a clean solution. Too bad we can't Chris Lattner
use Blocks for our callbacks ;-) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65083 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-19Fix a long standard problem with clang retaining "too much" sugar Chris Lattner
information about types. We often print diagnostics where we say "foo_t" is bad, but the user doesn't know how foo_t is declared (because it is a typedef). Fix this by expanding sugar when present in a diagnostic (and not one of a few special cases, like vectors). Before: t.m:5:2: error: invalid operands to binary expression ('typeof(P)' and 'typeof(F)') MAX(P, F); ^~~~~~~~~ t.m:1:78: note: instantiated from: #define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; }) ^ After: t.m:5:2: error: invalid operands to binary expression ('typeof(P)' (aka 'struct mystruct') and 'typeof(F)' (aka 'float')) MAX(P, F); ^~~~~~~~~ t.m:1:78: note: instantiated from: #define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; }) ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65081 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-17fix notes so that they are always filtered with the same logic Chris Lattner
as the last non-note diagnostic that preceeded them. This ensures that diagnostics in main files which have notes with locations in system headers get all the bits and pieces emitted or not in a unit. This fixes PR3215. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64746 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-04Some name-lookup-related fixes, from Piotr Rak!Douglas Gregor
- Changes Lookup*Name functions to return NamedDecls, instead of Decls. Unfortunately my recent statement that it will simplify lot of code, was not quite right, but it simplifies some... - Makes MergeLookupResult SmallPtrSet instead of vector, following Douglas suggestions. - Adds %qN format for printing qualified names to Diagnostic. - Avoids searching for using-directives in Scopes, which are not DeclScope, during unqualified name lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63739 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-23Added virtual method DiagnosticClient::IncludeInDiagnosticCounts(). This is ↵Ted Kremenek
used by Diagnostics to determine if a diagnostic sent to a given DiagnosticClient should be included in the count of diagnostics. The default implementation of this method returns 'true'. Implemented DiagCollector::IncludeInDiagnosticCounts() to return 'false' so that the batching of diagnostics for use with BugReporter doesn't mess up the count of real diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62873 91177308-0d34-0410-b5e6-96231b3b80d8
