8d442c2dc4 * Fix multiplication by powers of two and otherwise
* Clarify variable name (StoreInst SI instead of LI)

d88998db01 Pull out code shared between GV forward-decl and definition processing.
This gives us only a single call site for setValueNameMergingDuplicates.
The next stage is the start merging them together.

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.

2e2ed2995a Revamp handling of labels. In particular, if we create a forward reference
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.

46b002cd9b Various cleanups:
- Remove tabs
- 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.

011bed5ef8 Fix a backwards compatibility bug found by Tanya. In version 1.2, the
global type plane starts with a length and the TypeTyID value to identify
the type plane has having type definitions. This doesn't happen in 1.3
because the types are read from a known position in the file. However, the
TypeTyID must be read in (and ignored) if its a 1.2 bytecode file.

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.

  included/needed.
- Remove defunct BCR_TRACE lines
- Standardize error handling with the PARSE_ERROR macro.
- Integrate ConstantReader.cpp and InstructionReader.cpp and reorgnize
  the definition order so that gcc has a chance at optimizing this module
- Standardize case and style of method names.
- Eliminate unneeded header files
- Prepare for Type != Value (bug122) change by splitting Types into their
  own data structures.
- Implement the BytecodeHandler interface calls.
- Provide default implementation of BytecodeHandler interface.

more operand in GEPOps than there are types in GEPTypes: the pointer that is the
first operand of the GEP instruction.

c7fd0f4675 Use correct add*Imm form in more BuildMI calls.
Fix bug in emitGEPOperation where we weren't passing MBB, IP to getReg.
(hey, wouldn't a constant expression lowering pass be cool? huh huhuhuh)
Fix bug in emitGEPOperation where we might try to OR a constant into a
register which was too big to fit in the immediate field.
Support and, or, xor of longs.
