DEL_vacant_loop: Vacant Loop Elimination
C/C++ <Optimize>[Details...][Miscellaneous][Delete vacant loop]
MAX_unroll: Loop Expansion Maximum Number Specification
C/C++ <Optimize>[Details...][Miscellaneous][Specify maximum unroll factor :]
36
Command Line Format
DEL_vacant_loop = { 0 | 1 }
Description
When del_vacant_loop=0 is specified, even when there is no statements inside the loop, a
loop is not eliminated.
When del_vacant_loop=1 is specified, loops without statements inside are eliminated.
When this option is omitted, del_vacant_loop=0 is assumed.
Remarks
This option is valid only when the CPU type is H8SX or H8S(without legacy=v4 option).
Command Line Format
MAX_unroll = <numeric value>
Description
Specifies the maximum number of loop expansions. An integer from 1 to 32 can be specified
for <numeric value>. If any other value is specified, an error will occur.
When del_vacant_loop=1 is specified, loops with no internal processing are eliminated.
When this option is omitted, max_unroll=2 is assumed with speed or speed=loop[=2]
specified. For any other cases, max_unroll=1 is assumed.
Remarks
This option is valid only when the CPU type is H8SX or H8S(without legacy=v4 option).
When opt_range=noloop or opt_range=noblock is specified, max_unroll=1 is always the
default.
