Compares the enable_if attributes of two FunctionDecls, for the purposes of overload resolution.
Cand1's set of enable_if attributes are said to be "better" than Cand2's iff Cand1's first N enable_if attributes have precisely the same conditions as Cand2's first N enable_if attributes (where N = the number of enable_if attributes on Cand2), and Cand1 has more than N enable_if attributes.
Note that you can have a pair of candidates such that Cand1's enable_if attributes are worse than Cand2's, and Cand2's enable_if attributes are worse than Cand1's.

Standard conversion sequences only consider non-class types; for conversions that involve class types, use TryImplicitConversion. If a conversion exists, SCS will contain the standard conversion sequence required to perform this conversion and this routine will return true. Otherwise, this routine will return false and the value of SCS is unspecified.

Generates a 'note' diagnostic for an overload candidate.
We've already generated a primary error at the call site.
It really does need to be a single diagnostic with its caret pointed at the candidate declaration. Yes, this creates some major challenges of technical writing. Yes, this makes pointing out problems with specific arguments quite awkward. It's still better than generating twenty screens of text for every failed overload.
It would be great to be able to express per-candidate problems more richly for those diagnostic clients that cared, but we'd still have to be just as careful with the default diagnostics.

TryImplicitConversion - Attempt to perform an implicit conversion from the given expression (Expr) to the given type (ToType).
This function returns an implicit conversion sequence that can be used to perform the initialization. Given
void f(float f); void g(int i) { f(i); }
this routine would produce an implicit conversion sequence to describe the initialization of f from i, which will be a standard conversion sequence containing an lvalue-to-rvalue conversion (C++ 4.1) followed by a floating-integral conversion (C++ 4.9). Note that this routine only determines how the conversion can be performed; it does not actually perform the conversion. As such, it will not produce any diagnostics if no conversion is available, but will instead return an implicit conversion sequence of kind "BadConversion".
If SuppressUserConversions
, then user-defined conversions are not permitted. If AllowExplicit
, then explicit user-defined conversions are permitted.
AllowObjCWritebackConversion | Whether we allow the Objective-C writeback conversion, which allows __autoreleasing id* parameters to be initialized with __strong id* or __weak id* arguments. |
