2011-04-28More cleanup of template argument deduction and its handling ofDouglas Gregor
non-CVR qualifiers. We can now properly match address-space--qualified references during template argument deduction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130365 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-27t/clang/type-traitsJohn Wiegley
Patch authored by John Wiegley. These type traits are used for parsing code that employs certain features of the Embarcadero C++ compiler. Several of these constructs are also desired by libc++, according to its project pages (such as __is_standard_layout). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130342 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-24Implement most of the remaining logic in __is_literal type trait. ThisChandler Carruth

2011-04-23Begin tracking trivialness of move constructors and move assignmentChandler Carruth
operators in C++ record declarations. This patch starts off by updating a bunch of the standard citations to refer to the draft 0x standard so that the semantics intended for move varianst is clear. Where necessary these are duplicated so they'll be available in doxygen. It adds bit fields to keep track of the state for the move constructs, and updates all the code necessary to track this state (I think) as members are declared for a class. It also wires the state into the various trait-like accessors in the AST's API, and tests that the type trait expressions now behave correctly in the presence of move constructors and move assignment operators. This isn't complete yet due to these glaring FIXMEs: 1) No synthesis of implicit move constructors or assignment operators. 2) I don't think we correctly enforce the new logic for both copy and move trivial checks: that the *selected* copy/move constructor/operator is trivial. Currently this requires *all* of them to be trivial. 3) Some of the trait logic needs to be folded into the fine-grained trivial bits to more closely match the wording of the standard. For example, many of the places we currently set a bit to track POD-ness could be removed by querying other more fine grained traits on demand. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130076 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-23Implement basic __is_trivial type-trait support, enough to close PR9472.Chandler Carruth
This introduces a few APIs on the AST to bundle up the standard-based logic so that programmatic clients have access to exactly the same behavior. There is only one serious FIXME here: checking for non-trivial move constructors and move assignment operators. Those bits need to be added to the declaration and accessors provided. This implementation should be enough for the uses of __is_trivial in libstdc++ 4.6's C++98 library implementation. Ideas for more thorough test cases or any edge cases missing would be appreciated. =D git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130057 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-21Implement the preference for move-construction over copy-constructionDouglas Gregor
when returning an NRVO candidate expression. For example, this properly picks the move constructor when dealing with code such as MoveOnlyType f() { MoveOnlyType mot; return mot; } The previously-XFAIL'd rvalue-references test case now works, and has been moved into the appropriate paragraph-specific test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123992 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-06Revert r120808, my previous implementation of caching for the linkageDouglas Gregor

2010-12-04More anonymous struct/union redesign. This one deals with anonymous field ↵Francois Pichet
used in a constructor initializer list: struct X { X() : au_i1(123) {} union { int au_i1; float au_f1; }; }; clang will now deal with au_i1 explicitly as an IndirectFieldDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120900 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-03Implement caching for the linkage and visibility calculations ofDouglas Gregor
declarations. The motivation for this patch is that linkage/visibility computations are linear in the number of redeclarations of an entity, and we've run into a case where a single translation unit has > 6500 redeclarations of the same (unused!) external variable. Since each redeclaration involves a linkage check, the resulting quadratic behavior makes Clang slow to a crawl. With this change, a simple test with 512 redeclarations of a variable syntax-checks ~20x faster than before. That said, I hate this change, and will probably end up reverting it in a few hours. Reasons to hate it: - It makes NamedDecl larger, since we don't have enough free bits in Decl to squeeze in the extra information about caching. - There are way too many places where we need to invalidate this cache, because the visibility of a declaration can change due to redeclarations (!). Despite self-hosting and passing the testsuite, I have no confidence that I've found all of places where this cache needs to be invalidated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120808 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-29Move the management of the set of conversion functions in a C++ classDouglas Gregor
into CXXRecordDecl. The only part that we do not handle this way are using declarations, since that would require extra name lookup that we don't currently want to pay for.

completely into CXXRecordDecl, by adding a new completeDefinition() function.
