Description
Specifies whether the inter-module optimization is executed.
When optimize is specified, optimization is performed for the specified file at compilation or
assembly.
When nooptimize is specified, no optimization is executed for a module.
When this option is omitted, the default is optimize.
Table 4.8 shows the suboptions
Suboptions of Optimize Option
Provides all optimizations
Unifies same-value constants having the const
attribute. Constants having the const attribute are:
Deletes variables/functions that are not referenced.
The entry option should be specified.
accessible in the 8/16 bit absolute addressing
mode. The cpu option should be specified.
Investigates function calls, relocates registers and
deletes redundant register save or restore codes.
The entry option should be specified.
Creates a subroutine for the same instruction
sequence.
Replaces an instruction having a displacement or
an immediate value with a smaller-size instruction
when the code size of the displacement or
immediate value can be reduced.
Description
• Variables defined as const in C/C++ program
• Initial value of character string data
• Literal constant
