4.10.2.2 OPTIMIZATION

These options, shown in Figure 4-11, relate to optimizations performed by the compiler,

1. Optimization controls: These controls adjust the optimizations employed by the

compiler. See Section 4.8.42 “--OPT: Invoke Compiler Optimizations”. Select

an optimizations set (--OPT suboptions: all or none), or any of the custom

options below (--OPT suboptions: asm, asmfile, speed/space and debug).

2. Address Qualifier: This selector allows the user to select the behavior of the

address qualifiers. See Section 4.8.16 “--ADDRQUAL: Set Compiler

Response to Memory Qualifiers”.

3. Operation Mode: This selector allows the user to force another available operat-

ing mode (free, std or pro) other than the default. See

Section 4.8.37 “--MODE: Choose Compiler Operating Mode”. The operating

mode will affect OCG-optimizations
