Hi,
Yet another question: there are several root lists: gt_ggc_rtab,
gt_ggc_deletable_rtab, gt_pch_cache_rtab, gt_pch_scalar_rtb. Now what
is what? I see that gt_ggc_rtab is an "ordinary" list. The deletable
one seems to have things that can be always collected? The names of
the last two ones sug

Hi,
There is a root list, generated by gengtype from parsing the files
looking for those GTY markers.
So, if you look at ggc_mark_roots, you can see the walker that is
walking the root table.
If you look in your *build* directory, and grep for ggc_root_tab, you
will see where the roots are.
Some of the GCC roots live on the heap memory, e.g. ident_table. These
are not found by Boehm's GC by default. I've started fixing such
places by registering these additional roots. But it got me thinking:
how do the old GCC garbage collectors know about those roots? I do not
see any root regist

Copying me is fine for me.
