59073e02cc Add some asserts that the list of intervals returned by addIntervalsForSpills 
is sorted.  This is not the case currently, which is causing no end of
problems.

6097d13b2a remove the mbbi2mbbMap_, which was just keeping track of mbb order anyway. 
Heavily refactor handleVirtualRegisterDef, adding comments and making it more
efficient.  It is also much easier to follow and convince ones self that it is
correct :)

Add -debug output to the joine, showing the result of joining the intervals.

bebde759e5 * Use LI(S) to copy constants into registers intead of ADDI(S) as the latter is 
a funky way to "use" R0 for a 0-valued operand
* Add IMPLICIT_DEFs for incoming function arguments via registers to help the
  register allocator not clobber those registers
* Implement comparisons with longs
* Teach emitSelectOperation() to fold the SetCC operation

dd68469382 Implement folding of expressions like 'uint cast (int* getelementptr (int*

d2995df5b7 Improve codegen for the LLVM offsetof/sizeof "operator". Before we compiled 
this LLVM function:

int %foo() {
        ret int cast (int** getelementptr (int** null, int 1) to int)
}

into:

foo:
        mov %EAX, 0
        lea %EAX, DWORD PTR [%EAX + 4]
        ret

now we compile it into:

foo:
        mov %EAX, 4
        ret

This sequence is frequently generated by the MSIL front-end, and soon the malloc lowering pass and
Java front-ends as well..

a09000db75 ** Finally DeclareNewGlobalValue is dead! 
* Simplify a lot of code because type's cannot be in function symbol tables
* Fix memory leaks in handling of redefined function prototypes
* Don't use SymbolTable directly for stuff that we can go through the Module
  for.
* Fix some minor bugs on obscure testcases like:
      test/Feature/globalredefinition.ll
* Do not create GlobalVariable objects for forward referenced Functions!
* When forward referencing a function in a constant expression, do not create
  a placeholder, add a bunch of references to it, then turn around and
  replaceAllUsesOfWith on it with a new global, deleting the placeholder.
  Instead, when we find the real definition of the global, just use the
  placeholder instead of creating a new object.

This substantially simplifies the asmwriter and should even speed it up on
cases heavy in constantexprs (like C++, Java, MSIL)...

cb9d6a8f73 Fold setValueNameMergingDuplicates into ParseGlobalVariable, allowing us

GlobalVariables and then immediately destroy them when they are duplciate
definitions.

DeclareNewGlobalValue calls...

66028f208e Simplify code. Do not allow functions to be redefined more than once. 
Since the stupid '%X = const int 4' thing is gone, we can now simplify
setValueNameMergingDuplicates a bit more.

for a basic block, use it when the block is defined instead of deleting it
and creating a new one.  Also, only create at most ONE forward reference
for any block, instead of one for each forward reference.

8c89a0a1fd Now that basic blocks are eagerly inserted into the Function, we can use 
the funciton symbol table to check for conflicts instead of having to
keep a shadow named LocalSymtab.  Totally eliminate LocalSymtab.  Verified
that this did not cause a regression on the testcase for PR107.

8ab406d5bd A couple of substantial cleanup fixes: 
1. Split setValueName into two separate functions, one that is only used
     at function scope and doesn't have to deal with duplicates, and one
     that can be used either at global or function scope but that does deal
     with conflicts.  Conflicts were only in there because of the crappy old
     CFE and probably should be entirely eliminated.
  2. Insert BasicBlock's into the parent functions when they are created
     instead of when they are complete.  This effects name lookup (for the
     better), which will be exploited in the next patch.

b89e071aea Factor some code to handle "load (constantexpr cast foo)" just like 
"load (cast foo)".  This allows us to compile C++ code like this:

class Bclass {
  public: virtual int operator()() { return 666; }
};

class Dclass: public Bclass {
  public: virtual int operator()() { return 667; }
} ;

int main(int argc, char** argv) {
  Dclass x;
  return x();
}

Into this:

int %main(int %argc, sbyte** %argv) {
entry:
        call void %__main( )
        ret int 667
}

Instead of this:

int %main(int %argc, sbyte** %argv) {
entry:
        %x = alloca "struct.std::bad_typeid"            ; <"struct.std::bad_typeid"*> [#uses=3]
        call void %__main( )
        %tmp.1.i.i = getelementptr "struct.std::bad_typeid"* %x, uint 0, uint 0, uint 0         ; <int (...)***> [#uses=1]
        store int (...)** getelementptr ([3 x int (...)*]*  %vtable for Bclass, int 0, long 2), int (...)*** %tmp.1.i.i
        %tmp.3.i = getelementptr "struct.std::bad_typeid"* %x, int 0, uint 0, uint 0            ; <int (...)***> [#uses=1]
        store int (...)** getelementptr ([3 x int (...)*]*  %vtable for Dclass, int 0, long 2), int (...)*** %tmp.3.i
        %tmp.5 = load int ("struct.std::bad_typeid"*)** cast (int (...)** getelementptr ([3 x int (...)*]*  %vtable for Dclass, int 0, long 2) to int
("struct.std::bad_typeid"*)**)          ; <int ("struct.std::bad_typeid"*)*> [#uses=1]
        %tmp.6 = call int %tmp.5( "struct.std::bad_typeid"* %x )                ; <int> [#uses=1]
	ret int %tmp.6
        ret int 0
}

In order words, we now resolve the virtual function call.

- Standardize use of space around ( and ).
- Consolidate the ConstantPlaceHolder class
- Rename two methods to be more meaningful (ParseType, ParseTypes)
- Correct indentation of blocks
- Add documentation
- Convert input dependent asserts to error(...) so it throws instead.
Provide placeholder implementations of read_float and read_double that
still read in platform-specific endianess. When I figure out how to do
this without knowing the endianess of the platform, it will get implemented
correctly.

efffdc9408 As much as I hate to say it, the whole setNode interface for DSNodeHandles 
is HOPELESSLY broken.  The problem is that the embedded getNode call can
change the offset of the node handle in unpredictable ways.

As it turns out, all of the clients of this method really want to set
both the node and the offset, thus it is more efficient (and less buggy)
to just do both of them in one method call.  This fixes some obscure bugs
handling non-forwarded node handles.

0e25e1cdcf Adjust the slot machine to handle Types separately from Values. This was 
done by doubling up the data structures so that Type based equivalents are
used. A consequence of this is overloading of function members that take a
Type* instead of a Value*. Various other cleanups related to Type != Value
(bug 122) were also implemented.

24ab28f1e5 For bug 122: 
Separate Types from Values because Type no longer inherits from Value. The
changes for this are too numerous to list. In essence, any data structure
that contained a Value was doubled so that Types could be contained
similarly. New members include Types, TypeMap, CompactionTypes, and
CompactionTypeMap. Functions taking a Value* were overloaded with a variant
that takes a Type* that acts on the new data structures.

fc3c82a804 Add a trivially simple pass to delete unreachable blocks from the CFG. This 
pass is required to paper over problems in the code generator (primarily
live variables and its clients) which doesn't really have any well defined
semantics for unreachable code.

The proper solution to this problem is to have instruction selectors not
select blocks that are unreachable.  Until we have a instruction selection
framework available for use, however, we can't expect all instruction
selector writers to do this.  Until then, this pass should be used.

the simplifycfg pass.  Eliminating this makes bugpoint much more useful
