Suboption
Description
Specifies the minimum code size for the optimization with the same-code unification
(optimize=same_code). Specify a hexadecimal value from 8 to 7FFF.
When this option is omitted, the default is samesize=1E.
Remarks
When optimize=same_code is not specified, this option is unavailable.
Command Line Format
PROfile = <file name>
Description
Specifies a profile information file.
Specifiable profile information files are those output from the Hitachi Debugging Interface
Ver. 5.0 or later or from the HEW Ver. 2.0 or later.
When a profile information file is specified, inter-module optimization according to dynamic
information can be performed.
Table 4.9 shows optimizations influenced by a profile information input.
2. Movement is provided not in the function unit, but in the input file unit.

Relations Between Profile Information and Optimization
dynamically accessed more frequently.
Lowers the optimizing priority of functions that are
dynamically accessed frequently.
Allocates a function that is dynamically accessed
frequently near the calling function.
For the SH program, the optimization with
allocation is performed depending on the cache
size specified using the cachesize option.
