Example 4-2 Global register - declaration error
int x;
__global_reg(1) int x; // error
In C, __global_reg variables cannot be initialized at definition. Example 4-3 produces
an error in C, but not in C++.
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 inline keyword.
However, inline is not available in C90.
__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);
}
