d4abe8d28a The recalclulate method was a nasty hack that was once used by the -cee pass,
which never worked itself.  The cee pass still doesn't work, but it doesn't use
this method anymore anyway, so eliminate the method.

9eeb35760f Completely rewrite domset, idom, and domtree implementation. Now it is based
on the algorithm for directly computing immediate dominators presented in this
paper:

  A Fast Algorithm for Finding Dominators in a Flowgraph
  T. Lengauer & R. Tarjan, ACM TOPLAS July 1979, pgs 121-141.

This _substantially_ speeds up construction of all dominator related information.
Post-dominators to follow.

54a3f2b134 *** Significantly speed up type resultion
This change speeds up type resolution by checking to see if a type is
  recursive, and if it's not, using a more efficient algorithm.

  This dramatically reduces bytecode loading time of kc++, reducing time-to-jit
  kc++ --version to 17s from 33s

09ef1749f7 Completely rewrite support for the Value::use_* list. Now, all operations on
this list (except use_size()) are constant time.  Before the killUse method
(used whenever something stopped using a value) was linear time, and thus
very very slow for large programs.

This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc:

176.gcc:     77.07s -> 37.38s
177.mesa:     7.59s ->  5.57s
252.eon:     21.02s -> 19.52s (*)
253.perlbmk: 11.40s -> 13.05s
254.gap:      7.25s -> 7.42s

252.eon would speed up a whole lot more, but optimization time is being
dominated by the inlining pass, which needs to be fixed.

18c3f42894 This checkin basically amounts to a complete rewrite of the type-resolution
machinery.  This dramatically simplifies how things works, removes irritating
little corner cases, and overall improves speed and reliability.

Highlights of this change are:

1. The exponential algorithm built into the code is now gone.  For example
   the time to disassemble one bytecode file from the mesa benchmark went
   from taking 12.5s to taking 0.16s.
2. The linker bugs should be dramatically reduced.  The one remaining bug
   has to do with constant handling, which I actually introduced in
   "union-find" checkins.
3. The code is much easier to follow, as a result of fewer special cases.
   It's probably also smaller.  yaay.

6b94d6a603 Reverting back to the previous revision.
We want to check for length 5 because we might get the "llvm." string as the
name.  That string is in the LLVM namespace and should be checked as such.
We also don't have to worry about garbage data because (I believe) the string
class will return a valid value.  So, the switch statement will work and we
don't have to worry about the code wandering into segfault land.

be at least 6 characters, since something must follow the "llvm." string in the

dda7669997 Change the code to no longer compute the "type description" immediately when
the type is analyzed.  Instead, only compute it when requested (with
getDescription), and cached for reuse later.

This dramatically speeds up LLVM in general because these descriptions almost
_never_ need to be constructed.  The only time they are used is when a type is
<<'d.  Printing of modules by themselves uses other code to print symbolic
types when possible, so these descriptions are really only used for debugging.

Also, this fixes the particularly bad case when lots of types get resolved to
each other, such as during linking of large programs.  In these cases, the type
descriptions would be repeatedly recomputed and discarded even though: A. noone
reads the description before it gets resolved, and B. many many resolutions
happen at intermediate steps, causing a HUGE waste of time.

Overall, this makes the getTypeDesc function much more light-weight, and fixes
bug: Assembler/2002-07-08-HugePerformanceProblem.llx, which went from taking
1048.770u/19.150s (which is 17.5 MINUTES, on apoc), to taking 0.020u/0.000s,
which is a nice little speedup.  :)

10c22c6970 Changes to:
* Fix bug printing method types (oops when converting previous code)
* Move some of the code from Constant::getStrValue implementations here.
  This allows us to do a MUCH MUCH better job printing out complex constant
  values (think an array of structure pointers), because we print symbolic
  type names instead of structural.  The assistance when debugging is immense

Eventually, Constant::getStrValue should be removed (it existed before because
the asmwriter file was not in VMCore), and everyone should go through the
asmwriter that want's equivalent functionality.

5496a44cc2 * Remove obselete code for unsized arrays
* Add new function printTypeAtLeastOneLevel used to...
* Print the symbol table *WITH SYMBOLIC TYPES*.  Now we get:
       %tree = type { int, %tree*, %tree* }
  in the type definition section of the disassembled output instead of
       %tree = type { int, \2*, \2* }
  the different for the health benchmark and power are simply amazing.

d81ca8a752 * Make all of the refineAbstractType functions work identically
* Remove ambiguous code that caused problems with understanding how stuff
  worked.
* Implement DerivedType::typeIsRefined right.  Add a big comment talking
  about it.
* The removeUserFromConcrete method already checks to see if the type is
  not abstract, so no need to duplicate the test all over this code

This checkin makes all of the type parsing related failures work.  All
Assembler Regression tests now pass!

That was due to the StructType object not getting called multiple times
   to remove itself from the ATU list for an object, because it stopped
   getting queried due to this wrong test

68857bb2bf * Move DerivedType::addAbstractTypeUser from DerivedType.h
* Refactor a bunch of code.  Types now only remove one subelement at a time
  when they are told that they have changed
* Improve debugging output, add more assertions...
* FIX Bugs:
  * test/Regression/Assembler/2002-04-04-PureVirtMethCall.ll
  * test/Regression/Assembler/2002-04-04-PureVirtMethCall2.ll
  * The change to fix these bugs was the to ValTypeBase::refineAbstractType
    method.  Basically we #if 0'd out the chunk of code there and make the
    table get reorganized EVEN IF the type has the same pointer.  Merging
    opportunities were being missed!
