Subject Re: [DRLVM][JET] write barriers for C/C++-based GC
Date Tue, 10 Oct 2006 08:29:48 GMT
Fursov and Alex,

Since the JIT/VM can determine if GC needs write barrier by querying
gc_requires_barriers(), could you update your patch so that the flag
for doWB will be set when this function returns TRUE? This has no
impact on other GCs that don't require write barrier.

Thanks,
xiaofeng
