Looking at drlvm/trunk, it looks like vmcore/include/sync_bits.h defines the use of *(ref_ptr +4) for 32-bit environment. Just guessing that "#define BUSY_FORWARDING_OFFSET 0" is intended to tell the GC that it can use the least significant bit out of these four bytes. Is this correct? I would like to use this bit as an MMTk mark bit. Will this work? (Actually the name, BUSY_FORWARDING_OFFSET is probably not the best...)
There is also a gc/src/gc_header.h file that contains, "#define GC_OBJECT_MARK_BIT_MASK 0x80". This seems to step on top of sync_bits.h use of this area??? Can I assume gc_header.h is incorrect? -- Weldon Washburn Intel Middleware Products Division --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
