[Sablevm-developer] SableJIT/x86 outperforms SableJIT/ppc!

[David <db...@cs...>]

Hi,

I did a few improvements that results in super good improvements
in SableJIT (a retargetable JIT for SableVM) on x86.

Note that SableJIT on x86 now seems to outperform SableJIT on ppc.

Some results here:

What is interesting is that SableJIT consists of a simple baseline
compiler (no optimizer) that uses a RISC model for its retargetable
backend.  And now, x86 which does not fit that well with the model
is better...

(Yes, I know, for some benchmarks runs slower, working on that issue)


AMD Athlon 1200MHz
PowerPC G3 700MHz
Both system with 256MB and running Debian GNU/Linux
