6.58 Other Built-in Functions Provided by GCC(点击打开链接)这个页面最后面三个函数就是我们需要的: — Built-in Function: uint16_t __builtin_bswap16 (uint16_t x) Returns x with the order of the bytes reversed; for example, 0xaabb becomes 0xbbaa. Byte here always means exactly 8 bits./...
'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).

gentype fma(gentype a, gentype b, gentype c); /* Returns the correctly rounded floating - point representation of the sum of cwith the infinitely precise product of aand b.Rounding of intermediate products does not occur.Edge case behavior is per the IEEE 754 - 2008 standard. */ genty...
Functions LOOKUP() TheLOOKUPfunction finds a value in a single row or column and matches it with a value in the same position in a different row or column. The following is an example of LOOKUP formula syntax: =LOOKUP(Lookup_Value,Lookup_Vector,...
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, ...

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...
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 ...
