Have you tried good general purpose hash functions like murmur3 or
cityhash?
Another option is to use "hash" function that is bijection on integers

Please find test case and test results attached. (gcc-test1.shar.txt)
The long story short: only gcc-4.2 is affected, gcc 3.4, 4.4 and 4.6 are
ok. clang is ok. (test-cc.txt)
Nearly all of the workarounds I used in original test doesn't work in
this test case (see #ifdef BAD_FIX in sources).

Hi,
I was lucky to write a bit of code which gcc 4.2 fails to compile
correctly with -O2. Too keep long story short the code fails for gcc
from base system and last gcc 4.2 snapshot from ports. It works with gcc
4.3, gcc 4.4 on FreeBSD and Linux. Clang from base is also good. -O and

Nullfs patch I've forgotten to attach before.
It adds vfs.nullfs.buckets
unction (it might be FNV if not SFH). Hash32 is inappropriate
for binary data that results in poor distribution.

Hi,
I'd like to introduce shlib-compat -- an ABI compatibility checker for
shared libraries with symbol versioning. The idea of such tool was
discussed on mail lists before.
shlib-compat uses debugging info (dwarf) from compiled library to
compare definitions of exported symbols, i.e. no sources
Hello,
My project is about reimplementing namecache. In a few words it's
about generalizing UFS-like dirhash cache and exposing it to upper
layers so that it can be used for reliable full path lookup. The idea
is quite different from existing implementations in DragonflyBSD and
Linux, instead of m
