Incorrect behavior on delete function optimization option "-OD"
Version Information
V3.5.1, V4.0.5, V4.0.5c
Details
Incorrect behavior on delete function optimization option "-OD". The option "-OD" has no
influence. The code generation for specified function will not be skipped. The initial code of the
function is still part of the executable.
Example:
init.c:
void wait(void)
{
int a=0;
while(a<35000)
{
a++;
}
}
main.c:
extern void wait(void);
void main(void)
{
while(1)
{
wait();
}
}
Command Sequence
ccv850e -noobj -g main.c init.c -OI=wait -OD=wait -o v030121a
Workaround
Use linker option “-delete”. This causes the linker to remove functions that are not referenced in the final
executable.
