Richard Smith da83703ed4 Fix some dead stores which the static analyzer warned about. No functionality 
change (the problematic cases in ParseDecl.cpp are currently impossible).

Richard Smith 21f06f0fcb When diagnosing multiple mem-initializers in a delegating ctor, point to the delegating initializer, not to the first initializer. For good measure, also highlight the other initializer.

Dmitri Gribenko ad45ad6fe9 Comment parsing: don't parse comment marker followed by a digit as a command 
since no Doxygen command starts with a digit.

llvm-svn: 163909
 2012-09-14 16:35:35 +00:00
Dmitri Gribenko 578865b73c Comment parsing: support the "\invariant" command.

Simon Atanasyan d44138808f Do not use "lib32" directory to create a library/object files 
paths when target is MIPS 32-bit.

The patch reviewed by Chandler Carruth.

Douglas Gregor 5c65f62a1e Fix warning on qualified typedef with 'unused' attribute, from Jason Haslam! 
llvm-svn: 163874
 2012-09-14 05:10:40 +00:00
Douglas Gregor 0064c5968f In debugger mode, allow comparisons between pointers and integers 
without a cast. Fixes <rdar://problem/11830912>.

llvm-svn: 163873
 2012-09-14 04:35:37 +00:00
Douglas Gregor 6d149412c8 As we do with base and member initializers in a dependent class, delay 
type checking for non-static data member initializers in a dependent
class, because our ASTs lose too much information to when
type-checking an initializer. Fixes <rdar://problem/11974632>,
although the result is still rather unsatisfactory.

both a virtual and a non-virtual offset. PR13832.

llvm-svn: 163863
 2012-09-14 00:51:36 +00:00
Douglas Gregor c7203ba19c When computing the decltype of an expression, consider Objective-C 
ivar and property references as member accesses and produce the actual
type of the declaration. Fixes <rdar://problem/12031582>.

llvm-svn: 163858

Douglas Gregor 1af8ad49fd Actually rebuild function types properly when adjusting the function 
type of an instantiation.

Richard Smith ca24ed473b Revert r163829. The world (or libstdc++, at least) is not ready. 
llvm-svn: 163846
 2012-09-13 22:00:12 +00:00
Douglas Gregor 89f593a14c When we substitute into the type of a function based on the 
TypeSourceInfo, we may have lost some adjustments made to the type of
that function due to declaration merging. Adjust the resulting type
correspondingly. Fixes PR12948 / <rdar://problem/11552434>.

 2012-09-13 21:56:43 +00:00
Dmitri Gribenko 0b1a96a876 Comment to XML conversion: we try not to emit empty <Discussion> elements, but 
it is not possible to guarantee that without duplicating logic or buffering
<Discussion> element contents.  So, allow empty <Discussion> elements in schema.

llvm-svn: 163842
 2012-09-13 21:32:58 +00:00
Richard Smith b9c5a60045 Implement C++11 [conv.prom]p4: an enumeration with a fixed underlying type has 
integral promotions to both its underlying type and to its underlying type's
promoted type. This matters now that boolean conversions aren't permitted in
converted constant expressions (a la DR1407): an enumerator with a fixed
underlying type of bool still can be.

Douglas Gregor c5c01a60c2 Don't perform template argument deduction against invalid templates; 
it's likely to lead to a crash later on. Fixes PR12933 /

 2012-09-13 21:01:57 +00:00
Dmitri Gribenko b37d5e8a95 Comment parsing: handle \deprecated command. It is a block command, but it 
should be fine to use it without further explanations in the attached
paragraph, so the warning about empty paragraph was turned off for it.

llvm-svn: 163836
 2012-09-13 20:36:01 +00:00
Fariborz Jahanian a55f658a88 remove duplicate code. 
llvm-svn: 163833
 2012-09-13 20:26:40 +00:00
Douglas Gregor 43bc036e8a Promote the warning about extra qualification on a declaration from a 
warning to an error. C++ bans it, and both GCC and EDG diagnose it as
an error. Microsoft allows it, so we still warn in Microsoft
mode. Fixes <rdar://problem/11135644>.

Richard Smith 659d38bcd5 Use a "better" unicode character, to avoid buildbot breakage on bots which can print some unicode characters. 
llvm-svn: 163825
 2012-09-13 19:10:51 +00:00
Fariborz Jahanian 1dfeacefbc Move back the stuff about missing ownership attribute warning 
to SemaDeclObjC and apply some simplification per John's
comment. // rdar://12280826

llvm-svn: 163824
 2012-09-13 18:53:14 +00:00
Richard Smith fab4b1a40c Make TextDiagnostic more robust against SourceLocations which point into the 
middle of UTF-8 characters, and avoid walking to such positions when adjusting
column ranges for display. Fixes a couple of hangs when rendering diagnostics.

Ted Kremenek e5c0a9bad4 When warning about unsafe uses of dispatch_once, specially handle the 
crazy case where dispatch_once gets redefined as a macro that calls
_dispatch_once (which calls the real dispatch_once).  Users want to
see the warning in their own code.

Fixes <rdar://problem/11617767>

llvm-svn: 163816
 2012-09-13 18:18:37 +00:00

not what most people want -- it starts a new paragraph).

Ted Kremenek b47e6bc597 Conditionally parse documentation comments in system headers by 
passing -fretain-comments-from-system-headers.  By default, the
compiler no longer parses such documentation comments, as they
can result in a noticeable compile time/PCH slowdown.

Jordan Rose 510260c2bf Format strings: %D, %U, and %O are valid on Darwin (same as %d, %u, %o). 
These will warn under -Wformat-non-iso, and will still be rejected
outright on other platforms.

Ted Kremenek edf22edca0 Teach -Wuninitialized to recognize common "noreturn" idioms in 
Objective-C related to NSException.

Fixes <rdar://problem/12287498>

I debated whether or not this logic should be sunk into the CFG
itself.  It's not clear if we should, as different analyses may
wish to have different policies.  We can re-evaluate this in the
future.
