Chris Lattner c2d140156c The __weak and __strong defines are common to all darwin targets
and are even set in C mode.  As such, move them to Targets.cpp.

__OBJC_GC__ is also darwin specific, but seems reasonable to always
define it when in objc-gc mode.

This fixes rdar://6761450

Douglas Gregor 23d75bb326 Build system changes to use TableGen to generate the various
diagnostics. This builds on the patch that Sebastian committed and
then revert. Major differences are:

  - We don't remove or use the current ".def" files. Instead, for now,
    we just make sure that we're building the ".inc" files.
  - Fixed CMake makefiles to run TableGen and build the ".inc" files
    when needed. Tested with both the Xcode and Makefile generators
    provided by CMake, so it should be solid.
  - Fixed normal makefiles to handle out-of-source builds that involve
    the ".inc" files.

I'll send a separate patch to the list with Sebastian's changes that
eliminate the use of the .def files.

Douglas Gregor 4ea568f213 Add a notion of "post-diagnostic hooks", which are callbacks attached
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.

Ted Kremenek 0666a6ce70 Selector: (changes made after discussing this more with Steve Naroff)
- Make Selector::getAsIdentifierInfo() private.  Using IdentifierInfo* in
  Selector is an implementation detail that clients shouldn't think about.
- Modify diagnostic emission in Sema::ProcessPropertyDecl to not use
  Selector::getAsIdentifierInfo() (which could crash when IdentifierInfo* is
  null) and instead use Selector::getAsString().
- Tidy up Selector::getAsString() implementation.

Chris Lattner 1a84994c46 allocate MultiKeywordSelector's out of a bump pointer allocator instead of malloc.
This has two advantages 1) no more leaking them, 2) fewer calls to malloc.

This changes us from calling malloc 3685/1390/883/2974/1185 times respectively on
16/20/24/28/32 byte objects when parsing cocoa.h with pth and -disable-free to
calling it 2816/1020/702/2903/1168 times each respectively.

Chris Lattner 5c3529634a implement support for propagating *features* down to the code generator
and defining target-specific macros based on them (like __SSE3__ and 
friends).  After extensive discussion with Daniel, this work will need
driver support, which will translate things like -msse3 into a -mattr 
feature.  Until this work is done, the code in clang.cpp is disabled and
the X86TargetInfo ctor still defaults to SSE2.  With these two things
changed, this code will work.  PR3634

Douglas Gregor 96977da72c Clean up and document code modification hints.
llvm-svn: 65641
2009-02-27 17:53:17 +00:00
Douglas Gregor 87f95b0a6a Introduce code modification hints into the diagnostics system. When we
know how to recover from an error, we can attach a hint to the
diagnostic that states how to modify the code, which can be one of:

  - Insert some new code (a text string) at a particular source
    location
  - Remove the code within a given range
  - Replace the code within a given range with some new code (a text
    string)

Right now, we use these hints to annotate diagnostic information. For
example, if one uses the '>>' in a template argument in C++98, as in
this code:

  template<int I> class B { };
  B<1000 >> 2> *b1;

we'll warn that the behavior will change in C++0x. The fix is to
insert parenthese, so we use code insertion annotations to illustrate
where the parentheses go:

test.cpp:10:10: warning: use of right-shift operator ('>>') in template
argument will require parentheses in C++0x
  B<1000 >> 2> *b1;
         ^
    (        )


Use of these annotations is partially implemented for HTML
diagnostics, but it's not (yet) producing valid HTML, which may be
related to PR2386, so it has been #if 0'd out.

In this future, we could consider hooking this mechanism up to the
rewriter to actually try to fix these problems during compilation (or,
after a compilation whose only errors have fixes). For now, however, I
suggest that we use these code modification hints whenever we can, so
that we get better diagnostics now and will have better coverage when
we find better ways to use this information.

This also fixes PR3410 by placing the complaint about missing tokens
just after the previous token (rather than at the location of the next
token).

Chris Lattner 810d330cd3 Fix a long standard problem with clang retaining "too much" sugar
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; })

Chris Lattner d2a2c13474 fix notes so that they are always filtered with the same logic
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.

Chris Lattner 9dc9c206d3 track "just a little more" location information for macro instantiations.
Now instead of just tracking the expansion history, also track the full
range of the macro that got replaced.  For object-like macros, this doesn't
change anything.  For _Pragma and function-like macros, this means we track
the locations of the ')'.

This is required for PR3579 because apparently GCC uses the line of the ')'
of a function-like macro as the location to expand __LINE__ to.

Chris Lattner 88ea93e6b4 lower the interface to getLineNumber like we did for
getColumnNumber.  This fixes a FIXME in 
SourceManager::getPresumedLoc because we now just decompose
the sloc once.

Chris Lattner e4ad417664 make SM::getColumnNumber take a predecomposed FileID/offset, which
makes it clear to clients that they have to pick an instantiation
or spelling location before calling it and allows optimization based
on that.

Chris Lattner c8233df64b switch SourceManager from using an std::map and std::list of
ContentCache objects to using a densemap and list, and allocating
the ContentCache objects from a bump pointer.  This does not speed
up or slow down things substantially, but gives us control over 
their alignment.

Chris Lattner 7368d581c1 Split the single monolithic DiagnosticKinds.def file into one
.def file for each library.  This means that adding a diagnostic

Chris Lattner f1ca7d3e02 Introduce a new PresumedLoc class to represent the concept of a location
as reported to the user and as manipulated by #line.  This is what __FILE__,
__INCLUDE_LEVEL__, diagnostics and other things should follow (but not 
dependency generation!).  

This patch also includes several cleanups along the way: 

- SourceLocation now has a dump method, and several other places 
  that did similar things now use it.
- I cleaned up some code in AnalysisConsumer, but it should probably be
  simplified further now that NamedDecl is better.
- TextDiagnosticPrinter is now simplified and cleaned up a bit.

This patch is a prerequisite for #line, but does not actually provide 
any #line functionality.

Chris Lattner 6d61c3e6df make -print-stats print stats about the amount of the SLoc
address space we used up.  Some interesting data:

For c99-intconst-1.c:
6912762 SLocEntry's allocated, 25592386B of Sloc address space used.

For cocoa.h:
26469 SLocEntry's allocated, 10278752B of Sloc address space used.

For carbon.h:
27364 SLocEntry's allocated, 12398141B of Sloc address space used.

Clearly 2G of sloc address space should be enough for anyone?!

Chris Lattner 4fa23625ab Check in the long promised SourceLocation rewrite. This lays the
ground work for implementing #line, and fixes the "out of macro ID's" 
problem.

There is nothing particularly tricky about the code, other than the
very performance sensitive SourceManager::getFileID() method.
