Chris Lattner 5274757b62 The second element of the iterator is really an offset, not a link

Chris Lattner e515976a11 * Significantly refactor GraphWriter into a class.

Chris Lattner cf5eb3317a - Generic graph printing infrastructure changes: 
* Only print outgoing edges from a cell if the destination isn't null.
       This is important for DSGraphs, which have sources with no edges.
     * Allow Node attributes to override shape of the node

 2002-10-14 03:30:23 +00:00
Chris Lattner 69ce8674b5 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to

Vikram S. Adve d77030bd76 Use vectors instead of hash_maps for issueGaps and conflictLists. 
These hash lookups were a major sink of time because they happen so often!

    constants.

Chris Lattner 9a389b3cce The wall clock timer (implementing using the RTC or cycle counter on x86) is 
so much more accurate than the per process timers that we get better results
(less noise) by sorting according to wall time than process time.

Chris Lattner 06f9532c8a - Remove the User::eraseOperand method which is never used, really 
dangerous, and not something we want to expose.

 2002-10-01 23:41:17 +00:00
Chris Lattner c758fe6b72 - Rework Statistics: 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
