Objective-C 中使用@来表示其对C语言的扩展,由编译器提供支持,也叫做compiler directives,比如@interface, @implementation等,下面一一介绍: @interface 相当于类的声明,像是C++中.h文件中包含的类声明信息。跟Java中的interface是不一样的。interface file就是.h文件。在声明一个新类时,
There is no#definepreprocessor directive in F#. You must use the compiler option or project settings to define the symbols used by the#ifdirective. Conditional compilation directives can be nested. Indentation is not significant for preprocessor directives. ...
I am using Parallel Studio XE2015 to compile a program that was compiled with Visual Fortran in the past. It looks like the compiler is ignoring !DIR$ and cDEC$ compiler directives. Initially, I thought cDEC$ had been deprecated, but !DIR$ is also being ignored. Do I nee...
Methods, systems and computer program products are provided for creating and compiling source program code using one or more compiler directives a programming environment. The compiler directives may provide information on how to compile the source program code. The compiler directives may apply to the...
The compiler accepts directives in the form of comments. To distinguish them from non-directive comments, directives require no space between the comment opening and the name of the directive. However, since they are comments, tools unaware of the directive convention or of a particular directive ...
This section describes new or changed compiler options and pragma directives in V12.1. You can specify compiler options on the command line. You can also modify compiler behavior through pragma directives embedded in your application source files. See the XL C/C++ Compiler Reference for detailed ...
DEC compiler directives in {D|C|I}VF over the years. Your explanation explains volumes. I know I've seen one such strange thing with IVF, but for the life of me can;t recall now. I've always found way to 'trick' the parser into doing what I needed, including fpp, so I'm ...

When inlining an S-function in C or C++, this should be the first noncomment line in the file, as in %implements "s_function_name" "C" The next noncomment lines will be %function directives specifying the functionality of the S-function. See the %language and GENERATE function ...
(e.g., report on attempts to auto-vectorize loops in the application code). Usually, most of these flags can also be activated with the use ofsource codedirectives (e.g., using pragmas in the case of the C programming language). Note that each compiler supports its own set of pragma...
