Chris Lattner 0e352963fd Emit series of conditionals with &&, emitting stuff like this: 
if (N1.getOpcode() == ISD::LOAD &&
        N1.hasOneUse() &&
        !CodeGenMap.count(N1.getValue(0)) &&
        !CodeGenMap.count(N1.getValue(1))) {

instead of this:

    if (N1.getOpcode() == ISD::LOAD) {
      if (N1.hasOneUse()) {
        if (!CodeGenMap.count(N1.getValue(0))) {
          if (!CodeGenMap.count(N1.getValue(1))) {

GCC not jump-threading across this common code, and produces far nicer
output.

Chris Lattner 5255c6c627 now that we have control over emission of the code, emit the code using nested 
"if" statements (indenting it appropriately, of course) instead of using goto's.

This inverts the logic for all of the if statements, which makes things simpler
to understand in addition to making the generated code easier to read.

Chris Lattner 4c4da201bf Change PatternCodeEmitter to emit code into a buffer instead of emitting it 
directly to the output file.  This makes things simple because the code doesn't
have to worry about indentation or the case when there is no goto.  It also
allows us to indent the code better without touching everything :)

Chris Lattner d02b05473c Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make it 
faster.  This cuts about 120 lines of code out of the legalizer (mostly code
checking to see if operands have changed).

It also fixes an ugly performance issue, where the legalizer cloned the entire
graph after any change.  Now the "UpdateNodeOperands" method gives it a chance
to reuse nodes if the operands of a node change but not its opcode or valuetypes.

This speeds up instruction selection time on kimwitu++ by about 8.2% with a
release build.

Chris Lattner 9dcce6da8e Several major changes: 
1. Pull out the expand cases for BSWAP and CT* into a separate function,
   reducing the size of LegalizeOp.
2. Fix a bug where expand(bswap i64) was wrong when i64 is legal.
3. Changed LegalizeOp/PromoteOp so that the legalizer never needs to be
   iterative.  It now operates in a single pass over the nodes.
4. Simplify a LOT of code, with a net reduction of ~280 lines.

Chris Lattner fd4a7f76a9 Eliminate the need for ExpandOp to set 'needsanotheriteration', as it already 
relegalizes the stuff it returns.

Add the ability to custom expand ADD/SUB, so that targets don't need to deal
with ADD_PARTS/SUB_PARTS if they don't want.

Evan Cheng e9025f1f3b Another folding problem: if a node r/w chain or flag, don't fold it if it 
has already been selected. The number of use check is not strong enough since
a node can be replaced with newly created target node. e.g. If the original
node has two uses, when it is selected for one of the uses it is replaced with
another. Each node now has a single use but isel still should not fold it.

Duraid Madina 0ebb0b1c5c fix stack corruption! Previously, 16-byte whole-FP-register stores were 
being treated as needing only 8 bytes (though they were 16 byte aligned.)

This should fix a bunch of tests - anyone have any comments, though?

  - in Target.td , SpillSize and SpillAlignment seem dead - is this what
    Size and Alignment do now?
  - in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
    DeclaredSpillAlignment seem dead.
  - there are a bunch of comments here and there that don't clearly
    distinguish between 'size' and 'spillsize' etc. hmm.

Duraid Madina cc87402925 fix register corruption! (my god.) r15 is a scratch reg, using that as 
a frame pointer is a pretty doofus thing to do. use r5 instead, and
mark it callee-saved, coz that's what it is!

Chris Lattner c66da83a89 Speedup and simplify pass registration by the observation that there is 
exactly one PassInfo object per RegisterPass object and that their lifetimes
are the same.  As such, there is no reason for the RegisterPass object to
dynamically allocate the PassInfo object at compiler startup time: just inline
the object by-value.  This should reduce codesize, heap size, and startup time. Yaay.

Chris Lattner af044cc84b It doesn't make sense to give llc a list of passes on the command line, 
LLVM doesn't use it and it can't work anyway.

Chris Lattner 33081b4648 Make this more efficient in the following ways: 
1. Do not statically construct a map when the program starts up, this
   is expensive and cannot be optimized.  Instead, create a list.
2. Do not insert entries for all function in the module into a hashmap
   that lives the full life of the compiler.
