gcc -de and -dW not working

gcc -de and -dW not working

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".

(tested with gcc version 3.2 Mandrake Linux 9.0 3.2-1mdk)

Could someone test/confirm please? I have attatched my test
program. -gW does not seem to work either, -dr does work however. I
thought this might be because I had to enable the modes -fssa and
-fssa-ccp respectivly; (even though there was no warning) but this made
no difference, no output files were created.

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)

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?
