2010-02-28Implement PR6423 by using one token of lookahead to disambiguate Chris Lattner
an *almost* always incorrect case. This only does the lookahead in the insanely unlikely case, so it shouldn't impact performance. On this testcase: struct foo { } typedef int x; Before: t.c:3:9: error: cannot combine with previous 'struct' declaration specifier typedef int x; ^ After: t.c:2:2: error: expected ';' after struct } ^ ; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97403 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-28When laying out vtables for virtual bases in construction vtables, we need ↵Anders Carlsson
to check if the vtable is a primary base in the layout class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97402 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-28Support constant-evaluation of __builtin_nans* as well as the correct constantJohn McCall
evaluation of __builtin_nan*. Most of the work to make this work is in LLVM. Fixes <rdar://problem/7696712> and part of PR 5255. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97383 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-28More improvements to construction vtables; we know handle vbase offsets ↵Anders Carlsson
correctly (I hope). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97361 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-27Figured out why the test was failing, this will hopefully fix it.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97336 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-27Don't add this adjustments for pure virtual member functions.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97334 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-27XFAIL this for now. I have no idea why this test is failing on some ↵Anders Carlsson
machines. Looks like some sort of whitespace issue in FileCheck. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97332 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-27Fix crasher caused by setting a bit in a possibly empty bitvector whileTed Kremenek
doing printf format string checking. This is a recent regression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97318 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-27Fix another vtable layout bug; we weren't looking hard enough for overriden ↵Anders Carlsson
functions when determining if an overrider will ever be used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97306 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97304 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-27Fix a bug where we were generating an unnecessary vtable for a virtual base ↵Anders Carlsson
that's already a primary virtual base. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97303 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-27Robustify SourceManager::getLocation(), so that it returns anDouglas Gregor
end-of-line source location when given a column number beyond the length of the line, or an end-of-file source location when given a line number beyond the length of the file. Previously, we would return an invalid location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97299 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-27For printf format string checking, add support for positional format strings.Ted Kremenek
Along the way, coelesce some of the diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97297 91177308-0d34-0410-b5e6-96231b3b80d8

them under -Wbad-literal. They're still on by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97284 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Prevent rewriter crash when variable type is missing.Fariborz Jahanian
Fixes radar 7692183. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97281 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-26For printf format string checking, move the tracking of the data argument ↵Ted Kremenek
index out of Sema and into analyze_printf::ParseFormatString(). Also use a bitvector to determine what arguments have been covered (instead of just checking to see if the last argument consumed is the max argument). This is prep. for support positional arguments (an IEEE extension). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97248 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Rewriting of imported variable from outerFariborz Jahanian
blocks's argument in the inner block requires special treatment. Fixes radar 7692419. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97244 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Fix an assertion-on-error during tentative constructor parsing byJohn McCall
propagating error conditions out of the various annotate-me-a-snowflake routines. Generally (but not universally) removes redundant diagnostics as well as, you know, not crashing on bad code. On the other hand, I have just signed myself up to fix fiddly parser errors for the next week. Again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97221 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26An explicit specialization is allowed following an explicitDouglas Gregor
instantiation so long as that explicit specialization was declared previously. Fixes PR6160. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97210 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Implement semantic analysis for C++ [expr.new]p18-20, which describeDouglas Gregor
how we find the operator delete that matches withe operator new we found in a C++ new-expression. This will also need CodeGen support. On a happy note, we're now a "nans" away from building tramp3d-v4. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97209 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Support rewriting of property synthesis with retain/copyFariborz Jahanian
attributes. Fixes radar 7214439. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97203 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Commit Eli's fix for implicit conversions to array type. Fixes PR6264.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97202 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Make sure to mark constructors, operator new, and operator delete asDouglas Gregor
used when we instantiate C++ new expressions, delete expressions, and object-construction expressions. Fixes PR6424, although we can't test all of it until we finish implementing lookup of "operator delete" for new expressions (!). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97195 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26When we decide to re-use an existing CXXConstructExpr node, make sureDouglas Gregor
to mark the constructor as referenced. Fixes the narrow issue reported in PR6424, but there are a few other places that I'll fix before closing out that PR. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97185 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25When computing the composite pointer type for relational comparisons,Douglas Gregor
equality comparisons, and conditional operators, produce a composite pointer type with the appropriate additional "const" qualifiers if the pointer types would otherwise be incompatible. This is a small extension (also present in GCC and EDG in a slightly different form) that permits code like: void** i; void const** j; i == j; with the following extwarn: t.cpp:5:5: warning: comparison of distinct pointer types ('void **' and 'void const **') uses non-standard composite pointer type 'void const *const *' [-pedantic] i == j; ~ ^ ~ Fixes PR6346, and I'll be filing a core issue about this with the C++ committee. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97177 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Fux a bug where we were trying to add overriders for non-virtual bases of ↵Anders Carlsson
virtual bases more than once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97173 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Allow us to compare derived-to-base conversions between a referenceDouglas Gregor
binding and a copy-construction. Fixes an overloading problem in the Clang-on-Clang build. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97161 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Forgot to include nested protocols in collection, resulting inFariborz Jahanian
bogus warning. Fixes radar 7682116. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97157 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Don't try to finalize an ill-formed variable or one whose class type is ↵Douglas Gregor
ill-formed. Fixes PR6421 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97152 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25When comparing two method overload candidates during overload diagnostics,John McCall
skip the object argument conversion if either of the candidates didn't initialize it. Fixes PR6421, which is such a very straightforward extension of PR6398 that I should have worked it into the last test case (and therefore caught it then). Ah well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97135 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Fix a really trivial crasher and begin fleshing out one of the namespace testChandler Carruth
cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97134 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Add a new conversion rank to classify conversions between complex and scalarChandler Carruth
types. Rank these conversions below other conversions. This allows overload resolution when the only distinction is between a complex and scalar type. It also brings the complex overload resolutin in line with GCC's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97128 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Enhance the unused ivar checker to not consider an ivar to be accidentally ↵Ted Kremenek
unused when it is explicitly marked as unused via __attribute__((unused)). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97104 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Allow __attribute__((unused)) to be applied to ObjC ivars.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97103 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Use CXXPseudoDestructorExpr as the stored representation for dependentDouglas Gregor
expressions that look like pseudo-destructors, e.g., p->T::~T() where p has dependent type. At template instantiate time, we determine whether we actually have a pseudo-destructor or a member access, and funnel down to the appropriate routine in Sema. Fixes PR6380. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97092 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Catch more uses of uninitialized implicit conversion sequences.John McCall
When diagnosing bad conversions, skip the conversion for ignored object arguments. Fixes PR 6398. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97090 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Add UnixAPIChecker, a meta checker to include various precondition checks ↵Ted Kremenek
for calls to various unix/posix functions, e.g. 'open()'. As a first check, check that when 'open()' is passed 'O_CREAT' that it has a third argument. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97086 91177308-0d34-0410-b5e6-96231b3b80d8
