Hi,
I have a few queries on GGC, the GCC garbage collector,
and usage of GTY markers in GCC sources. I would be grateful
if someone could take some time out to answer these.
First off, several fields are marked "skip", though the
documents seem to strongly discourage this. For example,
see ssa_use_operand_t in tree.h.
Second, some of the tree nodes ending in variable-length
arrays do not seem to have the appropriate GTY "length"
attributes. For example, see struct tree_string's "str"
field in tree.h.
I guess these are done on purpose, but I can't make out
exactly why. :-/
Lastly, on the gcjx-branch, a simple patch to
get_output_file_with_visibility() makes it recognise
".hh" and ".cc" C++ source files with GTY markers.
My question is, is this sufficient? Do people foresee
any problems with this?
Thanks,
Ranjit.
