--- Comment #10 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- Created attachment 32214 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32214&action=edit preserve permanent values in a separate table vt_initialize still took way too long in the insn-recog testcase, going over the entire table so as to preserve constants and equivalences over and over and over. That's silly. Moving to a separate table everything that is permanent avoids this complexity without significant drawbacks. With this patch, vt_initialize time goes down from the improved 500 seconds to 5 seconds. Wheee!
