Random sample (with .ehframe stripped):
64bit ls:
-rwxr-xr-x 1 root root 76672 Oct 25 05:59 /bin/ls
text data bss dec hex filename
64847 7752 1136 73735 12007 /bin/ls
32bit ls:
-rwxr-xr-x 1 root root 68524 2002-09-09 22:56 /bin/ls
text data bss dec hex filename
65353 1112 872 67337 10709 /bin/ls
[< 1K .text growth, some .data growth due to 64bit pointers]
The data is where I'd say the bloat would be, and lo and behold is a
nearly 7-fold increase for the sample you give us _only_ in the .data
section.
This doesn't even include dynamically allocated data structures,
things that sit on the stack, etc.
I can definitely see the text staying roughly the same, that's not the
big cost, it's the larger data structures.
BTW, I bet your dynamic relocation tables are a bit larger too.
