I'm making all the changes except this one unless you insist. Giving a bitmap a name that ends in "id" is confusing IMO - that sounds like a number. I'll add the requested comment that its contents match open_chains. I'm also adding a small fix for DEBUG_INSNS with multiword hardregs which showed up in a checking-enabled bootstrap. We were adding the same rtl location to a chain multiple times and aborting later when we made a replacement of the first one with (clobber (const_int 0)), and tried to take REGNO of that when encountering the second du_chain with that location. Retesting currently. Bernd -- This footer brought to you by insane German lawmakers.
