'eval' if it consists of a single expression, or 'single' if it consists of a single interactive statement (in the latter case, expression statements that evaluate to something other than None will be printed).

gcc的__builtin_函数(注意前面是两个下划线) 说明: GCC provides a large number of built-in functions other than the ones mentioned above. Some of these are for internal use in the processing of exceptions or variable-length argument lists and will not be documented here because they may change...
GCC provides quite a lot of builtin functions. These functions are part of standard C offered by the compiler and may come in various variants as per the gcc. These are also termed as hardware specific functions which are internally implemented in assembly or we can say machine instructions, ...

[Chapter 1] 1.4 Built-in FunctionsSteven FeuersteinJohn Beresniewicz &Chip Dawes
There are literally hundreds of built-in functions in GLSL. Many of them are used to work with textures and memory and will be covered in detail in those contexts in this book. In this section, we’ll look at functions that deal strictly with data—basic math, matrix, vector, and data...
The library functions create and return objects that are properly templated on the iterable they are passed. These exact names of these types or precisely how they are templated is unspecified, you should rely on the functions described in this document. If you plan to use these functions in ...
