2010-01-12Introduce a specific representation for the ambiguous implicit conversionJohn McCall
sequence. Lots of small relevant changes. Fixes some serious problems with ambiguous conversions; also possibly improves associated diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93214 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Eliminate an embarrassing performance regression in C/ObjC, where weDouglas Gregor
were performing name lookup for template names in C/ObjC and always finding nothing. Turn off such lookup unless we're in C++ mode, along with the check that determines whether the given identifier is a "current class name", and assert that we don't make this mistake again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93207 91177308-0d34-0410-b5e6-96231b3b80d8

non-NULL before looking at the entity itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93199 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Allow VLAs in C++ if in GNU mode (GNU C++ permits them). Clang can now ↵David Chisnall
compile LanguageKit, although the resulting code crashes (although not in any of the functions that use VLAs). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93198 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11C++0x [dcl.typedef]p4, take 3, where we actually figure out what "thatDouglas Gregor
is not also a typedef-name" actually means. For anyone keeping score, that's John: 2, Doug: 0. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93196 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Use isa<ElaboratedType> rather than getAs<ElaboratedType>, since theDouglas Gregor
latter may (eventually) perform multiple levels of desugaring (thus breaking the newly-added tests) and the former is faster. Thanks, John! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93192 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Allow redefinitions of typedef-names within class scope when the typeDouglas Gregor
they redefine is a class-name but not a typedef-name, per C++0x [dcl.typedef]p4. The code in the test was valid C++98 and is valid C++0x, but an unintended consequence of DR56 made it ill-formed in C++03 (which we were luck enough to implement). Fixes PR5455. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93188 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-11When resolving a single function template specialization to aDouglas Gregor
function, be sure to adjust the resulting argument type to a pointer (if necessary). Fixes PR5910 and PR5949. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93178 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93168 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Add support for out-of-line definitions of conversion functionDouglas Gregor
templates. Previously, a little thinko in the code that replaced a conversion function template with its redeclaration was causing some very weird lookup behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93166 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Tighten up the "cannot return array or function type" diagnostic toDouglas Gregor
say either "array type" or "function type", whichever it is. No reason to make the user guess. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93164 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Implement name lookup for conversion function template specializationsDouglas Gregor
(C++ [temp.mem]p5-6), which involves template argument deduction based on the type named, e.g., given struct X { template<typename T> operator T*(); } x; when we call x.operator int*(); we perform template argument deduction to determine that T=int. This template argument deduction is needed for template specialization and explicit instantiation, e.g., template<> X::operator float*() { /* ... */ } and when calling or otherwise naming a conversion function (as in the first example). This fixes PR5742 and PR5762, although there's some remaining ugliness that's causing out-of-line definitions of conversion function templates to fail. I'll look into that separately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93162 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-11Roll out ASTContext::getTypeSizeInChars(), replacing instances ofKen Dyck
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits ones as appropriate. Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, fromQuantity(), and getQuantity() for clarity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93153 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-11Enhance ScanReachableSymbols::scan(). Now another OSAtomic test case passes.Zhongxing Xu
The old test case has a little mistake. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93148 91177308-0d34-0410-b5e6-96231b3b80d8

This with previous patch fixes a OSAtomic test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93146 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-11Switch RegionStore over to using <BaseRegion+raw offset> to storeTed Kremenek
value bindings. Along with a small change to OSAtomicChecker, this resolves <rdar://problem/7527292> and resolves some long-standing issues with how values can be bound to the same physical address by not have the same "key". This change is only a beginning; logically RegionStore needs to better handle loads from addresses where the stored value is larger/smaller/different type than the loaded value. We handle these cases in an approximate fashion now (via CastRetrievedVal and help in SimpleSValuator), but it could be made much smarter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Preliminary reworking of value-binding logic in RegionStore:Ted Kremenek
(1) Introduce a new 'BindingKey' class to match 'BindingValue'. This gives us the flexibility to change the current key value from 'const MemRegion*' to something more interesting. (2) Rework additions/removals/lookups from the store to use new 'Remove', 'Add', 'Lookup' utility methods. No "real" functionality change; just prep work and abstraction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93136 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-10Do not parse hexadecimal floating point literals in C++0x mode because they areSean Hunt
incompatible with user-defined literals, specifically with the following form: 0x1p+1 The preprocessing-number token extends only as far as the 'p'; the '+' is not included. Previously we could get away with this extension as p was an invalid suffix, but now with user-defined literals, 'p' might well be a valid suffix and we are forced to consider it as such. This patch also adds a warning in non-0x C++ modes telling the user that this extension is incompatible with C++0x that is enabled by default (previously and with other languages, we warn only with a compliance option such as -pedantic). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93135 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-10Improve code completion by introducing patterns for the various C andDouglas Gregor
C++ grammatical constructs that show up in top-level (namespace-level) declarations, member declarations, template declarations, statements, expressions, conditions, etc. For example, we now provide a pattern for static_cast<type>(expr) when we can have an expression, or using namespace identifier; when we can have a using directive. Also, improves the results of code completion at the beginning of a top-level declaration. Previously, we would see value names (function names, global variables, etc.); now we see types, namespace names, etc., but no values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93134 91177308-0d34-0410-b5e6-96231b3b80d8
