Hi all,
I wanted to checked what "gcc -Os" could do to help us in our Holy
Cruisade for Disk Space. Here are my results for i386:
e2fsprogs-1.21+1.22-WIP-0620/debian[682]$ du -sb e2fsprogs-bf-*
364544 e2fsprogs-bf-O2
356352 e2fsprogs-bf-Os
e2fsprogs-1.21+1.22-WIP-0620/debian[683]$ find e2fsprogs-bf-O2 -type f | xargs cat |
wc -c
499620
e2fsprogs-1.21+1.22-WIP-0620/debian[684]$ find e2fsprogs-bf-Os -type f | xargs cat |
wc -c
496904
/me still wonders in which files there are holes, that could account
for the fact that the raw files are larger than the space that they,
their symlinks, and their dir tree take on my 4k-blocks filesystem,
but clearly there are a couple of KBs to take here.
Unless you have objections, I'll build e2fsprogs-bf with -Os.
Probably many other packages would benefit from this flag as well...
Regards,
