VOLATILE_Loop: Disabling Optimization against Loop Iteration Condition
C/C++ <Other>[Miscellaneous options :][Treats loop condition as volatile qualified]
Byteenum: Enumeration Data Size
C/C++ <Other>[Miscellaneous options :] [Treat enum as char if it is in the range of char]
Command Line Format
VOLATILE_Loop
Description
Disables optimization of the loop iteration condition if it includes an external variable.
Note however that if type conversion is performed, if two or more external variables are
included, or if composite operation is performed, optimization may be performed.
Remarks
This option is valid only when the CPU type is H8SX or H8S(without legacy=v4 option).
If this option is specified, external variables within the loop are not optimized even though the
volatile option has not been specified.
Without this option, if the loop iteration condition is invariant in the loop, the loop iteration
condition may be eliminated.
Command Line Format
Byteenum
Description
Handles the declared enum data as char data or unsigned char data.
If this option is specified, the compiler selects the enum data type according to the range of the
members of the enum data. If the value is in the range from 128 to 127, the compiler handles
the data as char data, whereas if the value is in the range from 0 to 255, the data is handled as
unsigned char data.
When this option is not specified or at least one of the enum data members exceeds the above
range, even if this option is specified, the enum data is handled as int data.
