Volatile, NOVolatile: External Variable Optimization
C/C++ <Optimize>[ Details...][Global variables][Treat global variables as volatile qualified]
The variables to be accessed in short absolute addressing mode can also be specified by
#pragma abs8 and #pragma abs16, and keywords of _ _abs8 and _ _abs16. If both an
option and #pragma/keyword are specified, the #pragma/keyword specification is given
priority over the option.
Remarks
The section output by this option must be allocated to the short absolute address area at linkage.
For the range of the short absolute address area, refer to section 19.3, Access Range of Short
Absolute Addresses. For section name specifications for the short absolute address area, refer
to the description on section switching in section 10.2.1 (1), Extended Specifications Related
to Memory Allocation.
Command Line Format
Volatile
NOVolatile
Description
When volatile is specified, the compiler does not optimize external variables.
When novolatile is specified, the compiler optimizes external variables that do not have a
volatile specifier.
When this option is not specified, the compiler assumes that novolatile is specified.
Example
Source program
volatile int a;
int b;
void main(void){
}
a;
b;
