because it expects a reference and receives a non-l-value. For example, given: int foo(int &); template<int x> void b() { foo(x); } clang will now print "expects an l-value for 1st argument" instead of "no known conversion from 'int' to 'int &' for 1st argument". The change in wording (and associated code to detect the case) was prompted by comment #5 in PR3104, and should be the last bit of work needed for the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158691 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-10When performing a user-defined conversion via a constructor, be sureDouglas Gregor
to check whether the constructor is accessible. Fixes <rdar://problem/10202900>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141588 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Improve our handling of user-defined conversions as part of overloadDouglas Gregor
resolution. There are two sources of problems involving user-defined conversions that this change eliminates, along with providing simpler interfaces for checking implicit conversions: - It eliminates a case of infinite recursion found in Boost. - It eliminates the search for the constructor needed to copy a temporary generated by an implicit conversion from overload resolution. Overload resolution assumes that, if it gets a value of the parameter's class type (or a derived class thereof), there is a way to copy if... even if there isn't. We now model this properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101680 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

2009-02-02Steve set me straight on this one. GCC was right, EDG was wrong: theDouglas Gregor
direct-initialization following a user-defined conversion can select any constructor; it just can't employ any user-defined conversions. So we ban those conversions and classify the constructor call based on the relationship between the "from" and "to" types in the conversion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63554 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30Improve our handling of the second step in a user-defined conversionDouglas Gregor
sequence. Previously, we weren't permitting the second step to call copy constructors, which left user-defined conversion sequences surprisingly broken. Now, we perform overload resolution among all of the constructors, but only accept the result if it makes the conversion a standard conversion. Note that this behavior is different from both GCC and EDG (which don't agree with each other, either); I've submitted a core issue on the matter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63450 91177308-0d34-0410-b5e6-96231b3b80d8
