Thanks Eric for the fix as below.
I am continuing to develop my custom Garbage Collector for gec, with
four outstanding routines needed before stress testing.
1/ mark the stack, and I have basically worked out how I am going to
accurately mark references values on the stack [subject to testing ! ]
2/ make available to the GC a reference to the root object
3/ dispatch routine to call dynamic-type mark routine per id field
4/ [less urgent] work for expanded class attribute(s) that recursively
contain reference containing expanded class attribute(s)
Stress testing of the core C routines for memory allocation, random de-reference,
mark, scan and free is now working reliably with about 50/55 percent bytes-requested
vs bytes-allocated [I think from memory]. It is currently Linux specific, but with only
one smallish routine being platform specific [mmap dependent code].
I am also working on a class ET_ELF_X86_64_CODE_GENERATOR to generate a
Linux ELF X86_64 file, using a set of classes based loosely on the concepts in the
LLVM project, but that has a long way to go.
Regards,
Howard
