4.9.2 Usage
You can declare named register variables as global variables. You can declare some, but
not all, named register variables as local variables. In general, do not declare VFP
registers and core registers as local variables. Do not declare caller-save registers, such
as R0, as local variables.
4.9.3 Example
In the following example, foo is declared globally as a named register variable for the
register r0.
register int foo __asm("r0");
void func(void)
{
....
}
