Here need your help (liu chao jun)

[Chris Phillips]

Hi
The current status is that Shark isn't functional, the near future will
bring a very different version of hotspot that will hopefully stabilize
and provide
jsr 292 without the complexity of Ricochet frames and deep recursion.

We had to port zero to that hotspot [hsx25 and soon hsx24 for jdk7u
hopefully]
 (That port now already completed by  Roman Kennke, awaiting acceptance
by the hotspot folk).

After that we can begin the resurrecting Shark based on that hotspot to
the latest
llvm (3.1+?). But note that there are also some other openjdk  or icedtea
projects that have reduced some of the requirement for shark , such as the
arm 32 bit asm jit , the  ppc-aix-port, and the recently announced arm 64
port...

Cheers!
Chris
