Hi, all
Is there a document of command options about opt and LNO, now I have one
from AMD, but it did not have all the options, for example, there is no
-WOPT:icopy=off:copy=off in this document!

Subject: Re: [Open64-devel] How can I filter the constant propagation
optimization in open64
Just add the flags -WOPT:icopy=off:copy=off to turn off copy propagation.

Hi, all
for example:
int a;
int c;
a = 5;
int b;
b += a + c;
after open64 has compiled, in the whirl it is: b += 5 + c;
but what I want is: it is still b + = a + c;
any suggestions ?
