I don't know if anyone's already done this, but I figured I'd share
the results in case anyone was curious. I'm using j...@google.com's
script for parsing objdump output and sorting it.
These results are generated by building a Release mode chrome with
"-g2" added to get the line numbers. This is built with gcc on linux
with a tree checked out two days ago or so. No surprise, but stl code
figures prominently here. Looks like the webkit ref counting and
containers also show up.

So the text segment is 16.7MB. RefCounted.h:94 contributes to 2% of
the code size.
