c++filt usage

Hi all,
I am just trying to learn c++filt, there are not enough example usage available in the web....

I am writing a main.cpp file and trying to read the machine code....

g++ -S main.cpp -> gives me main.s

if I need to find out an demangled value, I could use

g++ -S main.cpp | c++filt <demangled name>

g++ -S main.cpp | c++filt _Z3gooi

gives me value goo(int i)// which is the signature,

Is there a way, where you replace the current main.s file with demangled values, for example, the _Z3gooi will be demangled as goo(int i) in the file itself, instead of console.... ????

How about
c++filt main.s >main.s+ ; ln main.s{,~} ; mv main.s{+,}

The link-and-move safety is surely overkill here, but you seem new so I offer that sequence as an example to learn from.


assembly, c++ compiler, filtering, g++ error
