Re: [gobo-eiffel-develop] Bug in gec ?

[Howard T. <how...@di...>]

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
