You also need -WOPT:dead=off. The flags related to dead store
elimination are these four:
-WOPT:dse=off:dead=off:bdce=0:spre=0
The best documentation about these flags, which are useful only to
developers, is by looking at the source files that implement them. In
this case, the relevant file is common/com/config_wopt.cxx.

In my code:
int a = 10;
then in the program I won't use the variable of a, but the open64 will
eliminate the statement of a = 10. I have tried the option of :
-WOPT:dse=off:dce=off:dce_alias=off:dce_global=off:dce_branch=off:bdce=off:epre=off:ivar_pre=off:lpre=off
-IPA:dve=off:fold_cvt=off.
but it does not work, any suggestions ?

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!

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 ?
