In my opinion though, this would be a good thing. For example with
the old readelf the output would contain lines like this:
51: 0000000000000000 0 FUNC GLOBAL DEFAULT UND getpa@GLIBC_2.2.5 (2)
Which is surely misleading as there is no function called "getpa".
Using -W gets the full function name:
51: 0000000000000000 0 FUNC GLOBAL DEFAULT UND
getpagesize@GLIBC_2.2.5 (2)
Admittedly the ellipsis does mean that the output does look overly
abbreviated, but at least it does not lie.
Cheers
Nick
