CONST_Var_propagate: const Constant Propagation
C/C++ <Optimize>[Details...][Global variables][Propagate variables which are const qualified]
LIBrary: Specific Library Function Inline Expansion
C/C++ <Optimize>[Details...][Miscellaneous][Inline memcpy/strcpy]
Command Line Format
CONST_Var_propagate = { 0 | 1 }
Description
When const_var_propagate=0 is specified, constant propagation for external variables
declared by const is disabled.
When const_var_propagate=1 is specified, constant propagation is performed even for
external variables declared by const.
When this option is omitted, const_var_propagate=1 is assumed.
Example
Remarks
This option is valid only when the CPU type is H8SX or H8S(without legacy=v4 option).
When opt_range=noblock is specified, const_var_propagate=0 is the default.
Variables declared by const in a C++ program cannot be controlled by this option (constant
propagation is always performed).
Command Line Format
LIBrary = { Function | Intrinsic }
Description
Regarding library functions memcpy and strcpy:
Remarks
Specifying library=intrinsic is valid only when the CPU type is H8SX.
<Source program image when const_var_propagate=1 is specified>
const int x = 1;
int A;
void f() {
}
void f() {
}
When library=function is specified, these functions are called as functions.
When library=intrinsic is specified, inline expansion is performed for these functions.
A = x;
A = 1;
/* x = 1 is propagated */
