2011-07-15Restore the C-style cast hack for enum template arguments,John McCall
which is required given the current setup for template argument deduction substitution validation, and add a test case to make sure we don't break it in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135262 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-17When printing a qualified type, look through a substituted templateDouglas Gregor
parameter type to see what's behind it, so that we don't end up printing silly things like "float const *" when "const float *" would make more sense. Also, replace the pile of "isa" tests with a simple switch enumerating all of the cases, making a few more obvious cases use prefix qualifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125729 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12Enter the context of the declared function template when performingJohn McCall
deduction and the final substitution, but not while substituting the explicit template arguments. Fixes rdar://problem/8537391 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116332 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-28When perform exact-qualifier-match template argument deduction,John McCall
properly account for the possibility that certain opaque types might be more qualified than they appear. Fixes PR7708. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112390 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-19When deducing the element type of an array, ignore qualifiers ifJohn McCall
the context allows us to ignore qualifiers on the array type itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111486 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-05TDK_InconsistentQuals is really totally different from TDK_Inconsistent.John McCall
Rename it to TDK_Underqualified to avoid this sort of confusion and give it its own diagnostic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110318 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-14Wire up '-Wignored-qualifiers' to the warning on 'const' in 'const int f()'.Chandler Carruth
This flag and warning match GCC semantics. Also, move it to -Wextra as this is a largely cosmetic issue and doesn't seem to mask problems. Subsequent fixes to the tests which no longer by default emit the warning. Added explicit test cases for both C and C++ behavior with the warning turned on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108325 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13When forming a function call or message send expression, be sure toDouglas Gregor
strip cv-qualifiers from the expression's type when the language calls for it: in C, that's all the time, while C++ only does it for non-class types. Centralized the computation of the call expression type in QualType::getCallResultType() and some helper functions in other nodes (FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant callers of getResultType() to getCallResultType(). Fixes PR7598 and PR7463, along with a bunch of getResultType() call sites that weren't stripping references off the result type (nothing stripped cv-qualifiers properly before this change). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108234 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-07Require a complete type before examining base classes during template argumentChandler Carruth
deduction. This requires refactoring the deduction to have access to the Sema object instead of merely the ASTContext. Still leaves something to be desired due to poor source location. Fixes PR6257 and half of PR6259. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95528 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-30More fixes to the handling of CVR-comparisons on array types. Adds a method toChandler Carruth
QualType to get CVR-qualifiers through array types, and switches the primary comparison methods to use it. This may allow simplifying some of the callers of getUnqualifiedArrayType. Also fix the normalizing of CV-qualification during template deduction to normalize through arrays and allow a more qualified deduced array type. This fixes PR5911. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92289 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Template argument deduction for template template parameters. ThisDouglas Gregor
permits, among other things, ripping apart and reconstructing templates via partial specialization: template<typename T> struct DeepRemoveConst { typedef T type; }; template<typename T> struct DeepRemoveConst<const T> { typedef typename DeepRemoveConst<T>::type type; }; template<template<typename> class TT, typename T> struct DeepRemoveConst<TT<T> > { typedef TT<typename DeepRemoveConst<T>::type> type; }; Also, fix a longstanding thinko in the code handling partial ordering of class template partial specializations. We were performing the second deduction without clearing out the results of the first deduction. It's amazing we got through so much code with such a horrendous error :( git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86893 91177308-0d34-0410-b5e6-96231b3b80d8
