2012-12-07clang/test: Remove "REQUIRES:LP64" in two tests. Each of them have explicit ↵NAKAMURA Takumi
triple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169587 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-29Reject uses of __int128 on platforms that don't support it. Also move the uglyRichard Smith
'getPointerWidth(0) >= 64' test to be a method on TargetInfo, ready to be properly cleaned up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168856 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-12clang/test: [PR8833] Introduce the feature "LP64" to suppress ↵NAKAMURA Takumi
LLP64-incompatible tests. I think some of them could be rewritten to fit also LLP64. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163699 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-10PR12964: __int128 and unsigned __int128 are promoted integral types, be sure toRichard Smith
consider them when enumerating builtin operator candidates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158293 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-04When adding built-in operator candidates for overload resolutionDouglas Gregor
involving 'restrict', place restrict on the pointer type rather than on the pointee type. Also make sure that we gather restrict from the pointer type. Fixes PR12854 and the major part of PR11093. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157910 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-05Many of the built-in operator candidates introduced into overloadDouglas Gregor
resolution require that the pointed-to type be an object type, but we weren't filtering out non-object types. Do so, fixing PR7851. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122853 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03When producing overload candidates for binary built-in operators, keepDouglas Gregor
the sets of available conversions for the first and second arguments separate. This is apparently the indent of C++ [over.built], and reduces the number of overload candidates generated, eliminating some ambiguities. Fixes PR8477. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118178 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-11Add an option -fshow-overloads=best|all to limit the number of overloadJeffrey Yasskin
candidates printed. We default to 'all'. At the moment, 'best' prints only the first 4 overloads, but we'll improve that over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105815 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-08A built-in overload candidate is consider a non-template function whenDouglas Gregor
determining whether one overload candidate is better than another. Fixes PR7319. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105642 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-13Improve the reporting of non-viable overload candidates by noting the reasonJohn McCall
why the candidate is non-viable. There's a lot we can do to improve this, but it's a good start. Further improvements should probably be integrated with the bad-initialization reporting routines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93277 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-06Improve the diagnostics used to report implicitly-generated class membersJohn McCall
as parts of overload sets. Also, refer to constructors as 'constructors' rather than functions. Adjust a lot of tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92832 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

2009-10-21Don't generate pointer types for void or base classes when findingDouglas Gregor
conversion types for builtin overloaded operator candidates; I misread this section in the standard the first time around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84788 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-30When overload resolution fails for an overloaded operator, show theDouglas Gregor
overload candidates (but not the built-in ones). We still rely on the underlying built-in semantic analysis to produce the initial diagnostic, then print the candidates following that diagnostic. One side advantage of this approach is that we can perform more validation of C++'s operator overloading with built-in candidates vs. the semantic analysis for those built-in operators: when there are no viable candidates, we know to expect an error from the built-in operator handling code. Otherwise, we are not modeling the built-in semantics properly within operator overloading. This is checked as: assert(Result.isInvalid() && "C++ binary operator overloading is missing candidates!"); if (Result.isInvalid()) PrintOverloadCandidates(CandidateSet, /*OnlyViable=*/false); The assert() catches cases where we're wrong in a +Asserts build. The "if" makes sure that, if this happens in a production clang (-Asserts), we still build the proper built-in operator and continue on our merry way. This is effectively what happened before this change, but we've added the assert() to catch more flies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83175 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24Implement support for equality comparisons (!=, ==) of memberDouglas Gregor
pointers, by extending the "composite pointer type" logic to include member pointer types. Introduce test cases for member pointer comparisons, including those that involve the builtin operator candidates implemented earlier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79925 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-24Rename clang to clang-cc.Daniel Dunbar
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
2009-01-13Add the proper restrictions on the left-hand argument of a built-inDouglas Gregor
assignment operator candidate (C++ [over.match.oper]p4). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62128 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Enable some more operator overloading tests, and don't look into an ↵Douglas Gregor
identifier for functions that might not have one git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59818 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Support overloading of the subscript operator[], including support forDouglas Gregor
built-in operator candidates. Test overloading of '&' and ','. In C++, a comma expression is an lvalue if its right-hand subexpression is an lvalue. Update Expr::isLvalue accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59643 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Added operator overloading for unary operators, post-increment, andDouglas Gregor
post-decrement, including support for generating all of the built-in operator candidates for these operators. C++ and C have different rules for the arguments to the builtin unary '+' and '-'. Implemented both variants in Sema::ActOnUnaryOp. In C++, pre-increment and pre-decrement return lvalues. Update Expr::isLvalue accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59638 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Built-in equality and relational operators have return type "bool" in C++,Douglas Gregor
not "int". Fix a typo in the promotion of enumeration types that was causing some integral promotions to look like integral conversions (leading to extra ambiguities in overload resolution). Check for "acceptable" overloaded operators based on the types of the arguments. This is a somewhat odd check that is specified by the standard, but I can't see why it actually matters: the overload candidates it suppresses don't seem like they would ever be picked as the best candidates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59583 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Implement support for operator overloading using candidate operatorDouglas Gregor
functions for built-in operators, e.g., the builtin bool operator==(int const*, int const*) can be used for the expression "x1 == x2" given: struct X { operator int const*(); } x1, x2; The scheme for handling these built-in operators is relatively simple: for each candidate required by the standard, create a special kind of candidate function for the built-in. If overload resolution picks the built-in operator, we perform the appropriate conversions on the arguments and then let the normal built-in operator take care of it. There may be some optimization opportunity left: if we can reduce the number of built-in operator overloads we generate, overload resolution for these cases will go faster. However, one must be careful when doing this: GCC generates too few operator overloads in our little test program, and fails to compile it because none of the overloads it generates match. Note that we only support operator overload for non-member binary operators at the moment. The other operators will follow. As part of this change, ImplicitCastExpr can now be an lvalue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59148 91177308-0d34-0410-b5e6-96231b3b80d8
