Q.
I wish to specify a register storage class and assign it to a register. How can it be done?
A.
Specify a register storage class for a local variable and to ensure that the variable is assigned to a register, specify a command option
"-fenable_register(-fER)" when compiling. However, variables that have some type cannot be assigned to a register.
Example for declaring register variable:
register int i
Also, when writing a register variable make sure it is not used in a function overlapping function calls.
