up with, even though it's perfectly conformant code.  :(

d98738fe4d Fix a bug that Chris asserts emphatically is a bug. The changed clause 
would always return false because the Type of a type value is always
Type::TypeTY and can never be a floating point type.

b7b1b9d4b2 Several clean ups suggested by Chris: remove tabs, make SlotMachine do lazy

GlobalValues).

dccf1747a1 Part of bug 122: 
This change removes the BuildBytecodeInfo flag from the SlotCalculator
class. This flag was needed to distinguish between the Bytecode/Writer
and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can
remove this flag and simplify some code. Also, some minor name changes
to CachedWriter.h needed to be committed (missed in previous commit).

58bad426cc Part of bug 122. Removed dependency of AsmWriter on SlotCalculator by 
incorporating a significantly simpler "SlotMachine" into this file. The
SlotMachine is tailored for use by only the AsmWriter whose requirements
for slot numbers are vastly different than from the Bytecode/Writer. Code
change passes all Feature and Regression tests.

2791d48685 Made it illegal to pass a Type* through one of the Value* interfaces. The

e6e0da0b9f Completely rewrote the class. SymbolTable now separates Type* from Value* in preparation\ 
for making Type not derive from Value. There are now separate interfaces \
for looking up, finding, and inserting Types and Values. There are also \
three separate iterator interfaces, one for type planes, one for the types \
(type type plane), and one for values within a type plane. See the \
documentation in the Header file.

2d7c5ae892 Fix for PR#330. 
When looking at getelementptr instructions, make sure to use a forwarded
type.  We want to do this because a DerivedType may drop its uses and then
refine its users, who may then use another user who hasn't been refined yet.
By getting the forwarded type, we always ensure that we're looking at a
Type that isn't in a halfway refined state.

Now, I should be able to put this stuff in PATypeHandle, but it doesn't work
for some reason.  This should do for now.

ded1ad2846 Refactor code. Now the intrinsic lowering pass tries to recycle preexisting

This fixes: CBackend/2004-02-15-PreexistingExternals.llx compiling it into:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_30 = memcpy(((int *)l27_A), ((unsigned )(long)l27_B), ((int )123u));

instead of:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_27 = l43_memcpy(l27_A, l27_B, 123u);

b771939ef3 Two problems with these lines of code: 
1. The "work" was not in the assert, so it was punishing the optimized release
 2. getNamedFunction is _very_ expensive in large programs.  It is not designed
    to be used like this, and was taking 7% of the execution time of the code
    generator on perlbmk.

Since the assert "can never fail", I'm just killing it.

7f7b7be528 Major changes. Now we only compactify individual type planes if it is in 
fact "profitable" to do so.  This makes compactification "free" for small
programs (ie, it is completely disabled) and even helps large programs by
not having to encode pointless compactification planes.

On 176.gcc, this saves 50K from the bytecode file, which is, alas only
a couple percent.

This concludes my head bashing against the bytecode format, at least for
now.

807e401607 Implement a bunch of symbolic constant folding opportunities. This implements 
testcase test/Regression/Assembler/ConstantExprFold.llx

Note that these kinds of things only rarely show up in source code, but are
exceedingly common in the intermediate stages of algorithms like SCCP.  By
folding things (especially relational operators) that use symbolic constants,
we are able to speculatively fold more conditional branches, which can
lead to some big simplifications.

It would be easy to add a lot more special cases here, so if you notice
SCCP missing anything "obvious", you know what to make smarter.  :)

b4e121c364 Rename ConstantHandling.* -> ConstantFolding.* 
Move a bunch of (now) private stuff from ConstantFolding.h into
ConstantFolding.cpp.

This _finally_ gets us to a place where we have a sane constant folder.  The
rules are:

1. LLVM clients now use ConstantExpr::get* methods to fold constants.  If they
   cannot be folded, a constantexpr is created, so these methods always return
   valid Constant*'s.
2. The implementation of ConstantExpr::get* uses the functions exposed by
   ConstantFolding.h to try to fold constants.  If they cannot be folded,
   they should return a null pointer.
3. The implementation of ConstantFolding can do whatever it wants, and only
   has one client (Constants.cpp)

This cuts down on the wierd dependencies, and eliminates the two interfaces.
The old constanthandling interface was especially bad for clients to use
because almost none of them took the failure condition into consideration,
thus leading to obscure problems.

734c9747df Check in two changes: 
The first change (which is disabled) compactifies all of the function constant
pools into the global constant pool, in an attempt to reduce the amount of
duplication and overhead.  Unfortunately, as the comment indicates, this is
not yet a win, so it is disabled.

The second change sorts the typeid's so that those types that can be used
by instructions in the program appear earlier in the table than those that
cannot (such as structures and arrays).  This causes the instructions to
be able to use the dense encoding more often, saving about 5K on 254.gap.
This is only a .65% savings though, unfortunately. :(

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.

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.  :)
