-dv -fdump-rtl-all question

[Sunzir Deepur]

Hi list,

Is it ok to assume that when I compile a C file (that is guranteed to have
some code in it) under the following flags, I always get the mentioned
VCG file (and do not get a bigger one) ?

Flags                              Maximum VCG file that is always created
=====                            ==============================
"      -dv -fdump-rtl-all"      .49.stack.vcg
"-O1 -dv -fdump-rtl-all"      .49.stack.vcg
"-O2 -dv -fdump-rtl-all"      .50.compgotos.vcg
"-O3 -dv -fdump-rtl-all"      .50.compgotos.vcg

So basically I want to assume the maximum vcg file that is created
is a function of the optimizations and not a function of the source file..

thank you!
