Fariborz Jahanian 5da7ecb245 Fixed a bug in building ctor-initializer AST.
llvm-svn: 75692
2009-07-14 22:40:50 +00:00
Eli Friedman bb0d9a5129 Remove -ftraditional option, which gcc doesn't actually support. Make
using -traditional and -traditional-cpp with clang an error because 
it's unsupported in clang and causes a significant change in the 
semantics of the language.

Steve Naroff 6b712a7ba1 Introduce Type::isAnyPointerType() and convert all clients (suggested by Chris).
I don't love the name, however it simplifies the code and is a worthwhile change. If/when we come up with a better name, we can do a search/replace.

2009-07-14 16:40:28 +00:00
Steve Naroff 5ec6ff7678 Add a "TypeSpecStartLoc" to FieldDecl. Patch contributed by Enea Zaffanella.
Note: One day, it might be useful to consider adding this info to DeclGroup (as the comments in FunctionDecl/VarDecl suggest). For now, I think this works fine. I considered moving this to ValueDecl (a common ancestor of FunctionDecl/VarDecl/FieldDecl), however this would add overhead to EnumConstantDecl (which would burn memory and isn't necessary).

llvm-svn: 75606
2009-07-14 03:20:38 +00:00
Argyrios Kyrtzidis 1506d9bc25 Introduce redecl_iterator, used for iterating over the redeclarations of a FunctionDecl or VarDecl.
It iterates over all the redeclarations, regardless of the starting point. For example:

1) int f();
2) int f();
3) int f();

if you have the (2) FunctionDecl and call redecls_begin/redecls_end to iterate, you'll get this sequence:
(2)
(1)
(3)

The motivation to introduce this was that, previously, if (3) was a function definition,
and you called getBody() at (2), it would not return it, since getBody() iterated over the previous declarations only,
so it would only check (2) and (1).

llvm-svn: 75604
2009-07-14 03:20:21 +00:00
Argyrios Kyrtzidis 0736c5ca3b Introduce FunctionDecl::getLatestDeclaration() and VarDecl::getLatestDeclaration().

2009-07-14 03:19:21 +00:00
Argyrios Kyrtzidis 11a846ab53 Fixes for a couple of things:
- Declaration context of ParmVarDecls (that we got from the Declarator) was not their containing function.
- C++ out-of-line method definitions didn't get an access specifier.

Both were exposed by a crash when emitting a C++ method to a PCH file (assert at Decl::CheckAccessDeclContext()).

Daniel Dunbar f5c79709bc Update debug info generation for ObjCObjectPointer changes.
- Previously this would crash on recursive types, and it was also incorrectly
   stripping off a level of indirection.
 - I'm not 100% convinced this is all correct, but it should be a monotonic
   improvment.

Zhongxing Xu 170e816eff Instead of recovering from a wrong invalidation, this patch aims to
invalidate the region correctly. It uses the cast-to type to invalidate 
the region when available. To avoid invalid cast-to type like 'void*' or 'id',
region store now only records non-generic casts of regions.

Ted Kremenek b63f71528e Enhance SimpleSValuator::EvalBinOpNN to recognize the trivial case
where we are comparing a symbolic value against itself, regardless of
the nature of that symbolic value.

This enhancement identified a case where RegionStoreManager is not
correctly symbolicating the values of the pointees of parameters.  The
failing test is now in 'test/Analysis/misc-ps-region-store.m', with
that test file now (temporarily) marked XFAIL.

Steve Naroff 7cae42b07a This patch includes a conceptually simple, but very intrusive/pervasive change.
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches.

This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic.

By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. 

Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks.

Douglas Gregor 27821cee82 Make ASTContext explicitly keep track of the declaration for the C
FILE type, rather than using name lookup to find FILE within the
translation unit. Within precompiled headers, FILE is treated as yet
another "special type" (like __builtin_va_list).

This change should provide a performance improvement (not verified),
since the lookup into the translation unit declaration 
forces the (otherwise unneeded) construction of a large hash table.
More importantly, with precompiled headers, the construction
of that table requires deserializing most of the top-level
declarations from the precompiled header, which are then unused.

Fixes PR 4509.

the references of a Decl.
References are mapped and retrieved using the primary declaration (Decl::getPrimaryDecl()) of a particular Decl.

Douglas Gregor c6d5edd2ed Add support for retrieving the Doxygen comment associated with a given
declaration in the AST. 

The new ASTContext::getCommentForDecl function searches for a comment
that is attached to the given declaration, and returns that comment, 
which may be composed of several comment blocks.

Comments are always available in an AST. However, to avoid harming
performance, we don't actually parse the comments. Rather, we keep the
source ranges of all of the comments within a large, sorted vector,
then lazily extract comments via a binary search in that vector only
when needed (which never occurs in a "normal" compile).

Comments are written to a precompiled header/AST file as a blob of
source ranges. That blob is only lazily loaded when one requests a
comment for a declaration (this never occurs in a "normal" compile). 

The indexer testbed now supports comment extraction. When the
-point-at location points to a declaration with a Doxygen-style
comment, the indexer testbed prints the associated comment
block(s). See test/Index/comments.c for an example.

Some notes:
  - We don't actually attempt to parse the comment blocks themselves,
  beyond identifying them as Doxygen comment blocks to associate them
  with a declaration.
  - We won't find comment blocks that aren't adjacent to the
  declaration, because we start our search based on the location of
  the declaration.
  - We don't go through the necessary hops to find, for example,
  whether some redeclaration of a declaration has comments when our
  current declaration does not. Similarly, we don't attempt to
  associate a \param Foo marker in a function body comment with the
  parameter named Foo (although that is certainly possible).
  - Verification of my "no performance impact" claims is still "to be
  done".

SFINAE in those cases where SFINAE should apply.

In addition, deal with the sticky issue where SFINAE only considers
substitution of template arguments into the *type* of a function
template; we need to issue hard errors beyond this point, as

Daniel Dunbar aa246cafaa Driver: Improve diagnostics for failed commands.
- Not all tools give good error messages, and sometimes the tool can fail w/o
   any error (for example, when signalled).

 - We suppress this message when the failing command is the compiler and it
   failed normally (exit code == 1), under the assumption that it gave a good
   diagnostic.

For example, for a linker failure we now get:
--
ddunbar@lordcrumb:tmp$ clang a.c b.c
ld: duplicate symbol _x in /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-bXYITq.o and /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-6uK4jD.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
--

For a compiler crash we get:
--
ddunbar@lordcrumb:tmp$ clang t.i
Assertion failed: (CGT.getTargetData().getTypeAllocSizeInBits(STy) == RL.getSize()), function layoutStructFields, file CodeGenTypes.cpp, line 573.
0   clang-cc          0x0000000100f1f1f1 PrintStackTrace(void*) + 38
... stack trace and virtual stack trace follow ...
clang: error: compiler command failed due to signal 6 (use -v to see invocation)
--

But for a regular compilation failure we get the usual:
--
ddunbar@lordcrumb:tmp$ clang c.c
c.c:1:6: error: invalid token after top level declarator
int x
     ^
1 diagnostic generated.
--

 - No test case, not amenable to non-executable testing. :/

Chris Lattner c61089a6c2 Key decisions about 'bool' vs '_Bool' to be based on a new flag in langoptions.
This is simple enough, but then I thought it would be nice to make PrintingPolicy
get a LangOptions so that various things can key off "bool" and "C++" independently.
This spiraled out of control.  There are many fixme's, but I think things are slightly
better than they were before.

One thing that can be improved: CFG should probably have an ASTContext pointer in it,
which would simplify its clients.

Argyrios Kyrtzidis 743e7db794 -Keep a reference to the ASTContext inside the TranslationUnitDecl.
-Introduce Decl::getASTContext() which returns the reference from the TranslationUnitDecl that it is contained in.

The general idea is that Decls can point to their own ASTContext so that it is no longer required to "manually" keep track and make sure that you pass the correct ASTContext to Decls' methods, e.g. methods like Decl::getAttrs should eventually not require a ASTContext parameter.
