2009-11-15When performing a static downcast as part of a static_cast, make sureDouglas Gregor
that we're dealing with canonical types like the documentation say (yay, CanQualType). Alas, this is another instance where using getQualifiers() on a non-canonical QualType got us in trouble. Good news: with this fix, Clang can now parse all of its own headers! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88848 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-14- Have TryStaticImplicitCast set the cast kind to NoOp when binding a ↵Sebastian Redl
reference. CheckReferenceInit already inserts implicit casts to the necessary types. This fixes an assertion in CodeGen for some casts and brings a fix for PR5453 close, if I understand that bug correctly. - Also, perform calculated implicit cast sequences if they're determined to work. This finally diagnoses static_cast to ambiguous or implicit bases and fixes two long-standing fixmes in the test case. For the C-style cast, this requires propagating the access check suppression pretty deep into other functions. - Pass the expressions for TryStaticCast and TryStaticImplicitCast by reference. This should lead to a better AST being emitted for such casts, and also fixes a memory leak, because CheckReferenceInit and PerformImplicitConversion wrap the node passed to them. These wrappers were previously lost. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88809 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-14When type-checking a static cast (or the static_cast part of a C-styleDouglas Gregor
cast) that is converting to a class type, enumerate its constructors as in any other direct initialization. This ensures that we get the proper conversion sequence. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88751 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22Try to instantiate templates before doing hierarchy checks in static_cast. ↵Sebastian Redl
Fixes PR5261. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84860 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25Implement C++ semantics for C-style and functional-style casts. This ↵Sebastian Redl
regresses Clang extension conversions, like vectors, but allows conversions via constructors and conversion operators. Add custom conversions to static_cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77076 91177308-0d34-0410-b5e6-96231b3b80d8

Tests and drivers updated, still need to shuffle dirs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67602 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-16Almost complete implementation of rvalue references. One bug, and a few ↵Sebastian Redl
unclear areas. Maybe Doug can shed some light on some of the fixmes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67059 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Implement pointer to member handling in static_cast.Sebastian Redl
Fix a stupid mistake in UnwrapSimilarPointers that made any two member pointers compatible as long as the pointee was the same. Make a few style corrections as suggested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63215 91177308-0d34-0410-b5e6-96231b3b80d8
