[Format]

-speed

[Description]

-	When the speed option is specified, optimization will be performed with emphasis on execution performance.

[Remarks]

-	When the speed option is specified, the following options are automatically specified based on the optimize option specification.

-	When optimize=max is specified

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

speed

loop=8

inline=250

const_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.

-	When optimize=2 is specified
