The additional files attached for internal compiler errors usually have special formats that they save as, such as .dump for Java. These formats are generally more difficult to analyze than regular files, but can still have very helpful information for solving the bug causing the crash.
Here, attempting to use a non-class type in a qualified name (T::foo) results in a deduction failure for f<int> because int has no nested type named foo, but the program is well-formed because a valid function remains in the set of candidate functions.
The gcc compiler (since 2017) looks for a comment in a switch statement if a case falls-thru to the next case. If an explicit indication of fall-thru is not found, then the compiler issues a warning about a possible coding problem. Inserting such a comment about fall-thru is a long standing convention, and the compiler has codified the practice ...
In computer programming, conditional compilation is a compilation technique which results in differring executable programs depending on parameters specified. This technique is commonly used when these differences in the program are needed to run it on different platforms, or with different versions of required libraries or hardware.
For the GCC compiler, thiscall is almost identical to cdecl: The caller cleans the stack, and the parameters are passed in right-to-left order. The difference is the addition of the this pointer , which is pushed onto the stack last, as if it were the first parameter in the function prototype.
An output parameter, also known as an out parameter or return parameter, is a parameter used for output, rather than the more usual use for input. Using call by reference parameters, or call by value parameters where the value is a reference, as output parameters is an idiom in some languages, notably C and C++, [ b ] while other languages have ...
An overloaded function is a set of different functions that are callable with the same name. For any particular call, the compiler determines which overloaded function to use and resolves this at compile time. This is true for programming languages such as Java. [10]
In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code. [1] Classes, methods, variables, parameters and Java packages may be annotated. Like Javadoc tags, Java annotations can be read from source files.
