2009-04-07The __weak and __strong defines are common to all darwin targetsChris Lattner
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 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68494 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-16Build system changes to use TableGen to generate the variousDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67058 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

2009-03-07Selector: (changes made after discussing this more with Steve Naroff)Ted Kremenek
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66313 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04allocate MultiKeywordSelector's out of a bump pointer allocator instead of ↵Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66017 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03implement support for propagating *features* down to the code generatorChris Lattner
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.

2009-02-27Clean up and document code modification hints.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65641 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26Introduce code modification hints into the diagnostics system. When weDouglas Gregor
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65570 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

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 ')'.
