Disclaimer: I haven't built Shark in a long time.

AFAIK, it used to work with LLVM version 3.4 as of March 2014[1]. There
has been some work being done in the openembedded world by Jens
Rehsack[2]. I think he got Shark to build with LLVM 3.5, which I
haven't tested.

The shark files live mostly in these dirs:
src/share/vm/shark/
src/cpu/zero/vm/

The configure options to build shark are along the lines of:
configure ... \
  --with-jvm-variants=zeroshark

If llvm-config isn't in your PATH you might want to set it in your
build script like this:
PATH=$PATH:/path/to/llvm/llvm-3.4-bin-install/bin

Hope this helps and good luck!

Cheers,
Severin
