Re: needless deep recursion in gt-c-decl.h

The slowdown appears to be in using a two-loop algorithm for marking

I'm point point is I'm not sure a two-loop algorithm is needed.
I got the impression is that the one-loop argorithm doesn't work
for trees because of references from trees to rtl, like DECL_RTL.
I don't understand how rtl to the same extent, but I also think
a single loop should be enough to avoid deep recursion.
I'm just concerned about slowing down gcc bit by bit.
