¶virtual bool canCallMismatchedFunctionType() const

Description

Returns true if the target allows calling a function through a pointer with a different signature than the actual function (or equivalently, bitcasting a function or function pointer to a different function type). In principle in the most general case this could depend on the target, the calling convention, and the actual types of the arguments and return value. Here it just means whether the signature mismatch could *ever* be allowed; in other words, does the target do strict checking of signatures for all calls.
