This is more a question for the cfe-users list, but as far as I know
there's no way to prevent redefinitions in source files.
Cheers.

Hi Team,
Consider the below C code,
#define AVAL 5
void func()
{
int a=5;
if(a==AVAL)
{
//Do something
}
else
{
//Do something else
}
}
My question is
Is it possible to override the value of AVAL through the -D option?
For eg is it possible to set the value of AVAL to 2 through -D in clang so
that the else part executes?
Also apart from -D option we are also open to other ways of achieving this
Thanks in advance
