-size

[Format]

-size

[Default]

Optimization is with emphasis on size.

[Description]

-	When the size option is specified, optimization will be performed with emphasis on code size.

[Remarks]

-	When the size option is specified, the following options are automatically specified based on the optimize option specification. Note however that if one of the following options is specified otherwise explicitly, that specified option becomes valid.

The processing for optimization in response to the optimization level selected for the optimize option includes the fine adjustment of many items other than those that can be specified through compiler options. Code produced with different levels of optimization will differ in the ways set by the compiler options listed in the tables below, but will also not match in other ways.

	Loop Expansion	Inline Expansion	Converting Constant Division into Multiplication	Scheduling Instructions	Constant Propagation of const Qualified Variables	Dividing Optimizing Ranges	Optimizing External Variable Accesses	Optimization Considering the Type of the Data Indicated by the Pointer
size	loop=1	inline=0	noconst_div	schedule	const_ copy	noscope	map* nomap*	alias=ansi

Note	The default is map when a C/C++ source program has been specified for input and output=abs or output=mot has been specified for output. For any other case, the default is nomap.
