2009-12-16Fix semantic diagnostics that embed English works, from Nicola Gigante!Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91503 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-16Switch the C++ new expression over to InitializationSequence, ratherDouglas Gregor
than using its own partial implementation of initialization. Switched CheckInitializerTypes over to InitializedEntity/InitializationKind, to help move us closer to InitializationSequence. Added InitializedEntity::getName() to retrieve the name of the entity, for diagnostics that care about such things. Implemented support for default initialization in InitializationSequence. Clean up the determination of the "source expressions" for an initialization sequence in InitializationSequence::Perform. Taught CXXConstructExpr to store more location information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91492 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91050 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-09Reimplement reference initialization (C++ [dcl.init.ref]) using theDouglas Gregor
new notion of an "initialization sequence", which encapsulates the computation of the initialization sequence along with diagnostic information and the capability to turn the computed sequence into an expression. At present, I've only switched one CheckReferenceInit callers over to this new mechanism; more will follow. Aside from (hopefully) being much more true to the standard, the diagnostics provided by this reference-initialization code are a bit better than before. Some examples: p5-var.cpp:54:12: error: non-const lvalue reference to type 'struct Derived' cannot bind to a value of unrelated type 'struct Base' Derived &dr2 = b; // expected-error{{non-const lvalue reference to ... ^ ~ p5-var.cpp:55:9: error: binding of reference to type 'struct Base' to a value of type 'struct Base const' drops qualifiers Base &br3 = bc; // expected-error{{drops qualifiers}} ^ ~~ p5-var.cpp:57:15: error: ambiguous conversion from derived class 'struct Diamond' to base class 'struct Base': struct Diamond -> struct Derived -> struct Base struct Diamond -> struct Derived2 -> struct Base Base &br5 = diamond; // expected-error{{ambiguous conversion from ... ^~~~~~~ p5-var.cpp:59:9: error: non-const lvalue reference to type 'long' cannot bind to a value of unrelated type 'int' long &lr = i; // expected-error{{non-const lvalue reference to type ... ^ ~ p5-var.cpp:74:9: error: non-const lvalue reference to type 'struct Base' cannot bind to a temporary of type 'struct Base' Base &br1 = Base(); // expected-error{{non-const lvalue reference to ... ^ ~~~~~~ p5-var.cpp:102:9: error: non-const reference cannot bind to bit-field 'i' int & ir1 = (ib.i); // expected-error{{non-const reference cannot ... ^ ~~~~~~ p5-var.cpp:98:7: note: bit-field is declared here int i : 17; // expected-note{{bit-field is declared here}} ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90992 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-19Deduce a ConstantArrayType from a value-dependent initializer listDouglas Gregor
rather than punting to a DependentSizedArrayType, tightening up our type checking for template definitions. Thanks, John! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89407 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-19Cope with an amusingly little anomaly with dependent types andDouglas Gregor
incomplete array initialization, where we have the following in a template: int a[] = { 1, 2, something-value-dependent }; // ... sizeof(a); The type of "a" appears to be a non-dependent IncompleteArrayType, but treating it as such makes the sizeof(a) fail at template definition time. We now correctly handle this by morphing the IncompleteArrayType into a DependentSizedArrayType with a NULL expression, indicating that its size has no corresponding expression (and, therefore, the type is distinct from others). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89366 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-16First part of changes to eliminate problems with cv-qualifiers andDouglas Gregor
sugared types. The basic problem is that our qualifier accessors (getQualifiers, getCVRQualifiers, isConstQualified, etc.) only look at the current QualType and not at any qualifiers that come from sugared types, meaning that we won't see these qualifiers through, e.g., typedefs: typedef const int CInt; typedef CInt Self; Self.isConstQualified() currently returns false! Various bugs (e.g., PR5383) have cropped up all over the front end due to such problems. I'm addressing this problem by splitting each qualifier accessor into two versions: - the "local" version only returns qualifiers on this particular QualType instance - the "normal" version that will eventually combine qualifiers from this QualType instance with the qualifiers on the canonical type to produce the full set of qualifiers. This commit adds the local versions and switches a few callers from the "normal" version (e.g., isConstQualified) over to the "local" version (e.g., isLocalConstQualified) when that is the right thing to do, e.g., because we're printing or serializing the qualifiers. Also, switch a bunch of Context.getCanonicalType(T1).getUnqualifiedType() == Context.getCanonicalType(T2).getQualifiedType() expressions over to Context.hasSameUnqualifiedType(T1, T2) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88969 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-26Improve error recovery in C++: when we hit 'implicit int' cases in C++,Chris Lattner
these are usually because the parser was thoroughly confused. In addition to typing the value being declared as an int and hoping for the best, we mark the value as invalid so we don't get chains of errors when it is used downstream. In C, implicit int actually is valid, so typing the thing as int is good and marking it invalid is bad. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74266 91177308-0d34-0410-b5e6-96231b3b80d8
