INFinite_loop: Elimination of Expression Preceding Infinite Loop
C/C++ <Optimize>[Details...][Global variables][Delete assignment to global variables before an
infinite loop]
Command Line Format
INFinite_loop = { 0 | 1 }
Description
When infinite_loop=0 is specified, an assignment expression for external variables that is
located immediately before an infinite loop is not eliminated.
When infinite_loop=1 is specified, an assignment expression that is located immediately
before an infinite loop and that is an assignment to the external variable that is not used in the
infinite loop is eliminated.
When this option is omitted, infinite_loop=0 is assumed.
Example
Remarks
This option is valid only when the CPU type is H8SX or H8S(without legacy=v4 option).
<Source program image when infinite_loop=1 is specified>

}
void f()

}
A = 1;
while(1) {}
while(1) {}
/* Assignment expression to external variable A */
/* A is not referenced */
/* Assignment expression to external variable A is eliminated */
