Hello Daniel,

Thank you for the reply.

I now see the output I was expecting, I think if I pass -de and -02 (or anything else it requires like -fssa) a warning that nothing will happen should be printed to stderr about the args I passed. Do you agree?

Could anyone tell me if there is a bug db online for gcc similar to bugzilla?

Regards

JG

please cc me in any replies

Hello,

The "-de" gcc argument does not create a .ssa file or any other
file; I tested with a simple test program "gcc -de -Wall -o main main.c".


ssa is not enabled by default.

Try gcc -de -Wall -O2 -fssa -o main main.c
(-O2 is required for enabling ssa to do anything, IIRC)
