How does this version, which has been committed to the debug-early
branch, look?
One more thing Richi. I merged trunk into the branch once again, and Go
broke. I tracked it down to a temporary that was being created late
that IMO shouldn't even get debug info.
The fact that it gets created with create_tmp_var_name() in the first
place is suspect. The problem is actually the type, which doesn't even
get passed through rest_of_type* or the debug_hooks->type_decl().
However, I see no reason to have these temporary variables even get fed
to the debugger, so I'm marking them as DECL_IGNORED_P.
If you want I can repost the whole compiler proper patch, but this is a
small enough change that y'all can just wave through.
I've committed the snippet below to the branch. Everything else is as
it was.
Branch retested on x86-64 Linux and has been merged with trunk.
