Compiler-specific Features
Example 4-3 Global register - initialization error
__global_reg(1) int x=1; // error in C, OK in C++
4.1.7 __inline
The __inline keyword suggests to the compiler that it compiles a C or C++ function
inline, if it is sensible to do so.
The semantics of __inline are exactly the same as those of the C++ inline keyword.
__inline is a storage class qualifier. It does not affect the type of a function.
Example
__inline int f(int x)
{
return x*5+1;
}
int g(int x, int y)
{
return f(x) + f(y);
}

4.1.8 __int64
The __int64 keyword is a synonym for the keyword sequence long long.
__int64 is accepted even when using --strict.

• --[no_]strict on page 2-84
• long long on page 3-8.
4.1.9 __INTADDR__
The __INTADDR__ operation treats the enclosed expression as a constant expression, and
converts it to an integer constant.
