- Subject: [patch] Add new DW_AT and DW_FORM codes for Fission
I'd like to add these new DW_AT and DW_FORM codes for the Fission project:
http://gcc.gnu.org/wiki/DebugFission
We're currently working on the Fission implementation in GCC, gold,
and binutils, but I'd like to at least lay claim to the actual values
to prevent overlap with any other extensions that someone might start
working on.
In GCC, we're working on the (git-only) google/debugfission branch.
We'll be sending gold and binutils patches soon.
Any objections? Is this OK for trunk in binutils and gcc trees?
