because they have an aggressive linker that does dead code stripping.

2. Codegen this comparison:

as:

3fe6c1d389 Legalize is no longer limited to cleverness with just constant shift amounts. 
Allow it to be clever when possible and fall back to the gross code when needed.

This allows us to compile:

long long foo1(long long X, int C) {
  return X << (C|32);
}
long long foo2(long long X, int C) {
  return X << (C&~32);
}

to:
_foo1:
        rlwinm r2, r5, 0, 27, 31
        slw r3, r4, r2
        li r4, 0
        blr


        .globl  _foo2
        .align  4
_foo2:
        rlwinm r2, r5, 0, 27, 25
        subfic r5, r2, 32
        slw r3, r3, r2
        srw r5, r4, r5
        or r3, r3, r5
        slw r4, r4, r2
        blr

instead of:

_foo1:
        ori r2, r5, 32
        subfic r5, r2, 32
        addi r6, r2, -32
        srw r5, r4, r5
        slw r3, r3, r2
        slw r6, r4, r6
        or r3, r3, r5

cf9d0acfef Fold the PPCISD shifts when presented with 0 inputs. This occurs for code 
like:
long long test(long long X, int Y) {
  return 1ULL << Y;
}
long long test2(long long X, int Y) {
  return -1LL << Y;
}

which we used to compile to:

_test:
        li r2, 1
        subfic r3, r5, 32
        li r4, 0
        addi r6, r5, -32
        srw r3, r2, r3
        slw r4, r4, r5
        slw r6, r2, r6
        or r3, r4, r3
        slw r4, r2, r5
        or r3, r3, r6
        blr
_test2:
        li r2, -1
        subfic r3, r5, 32
        addi r6, r5, -32
        srw r3, r2, r3
        slw r4, r2, r5
        slw r2, r2, r6
        or r3, r4, r3
        or r3, r3, r2
        blr

Now we produce:

_test:
        li r2, 1
        addi r3, r5, -32
        subfic r4, r5, 32
        slw r3, r2, r3
        srw r4, r2, r4
        or r3, r4, r3
        slw r4, r2, r5
        blr
_test2:
        li r2, -1
        subfic r3, r5, 32
        addi r6, r5, -32
        srw r3, r2, r3
        slw r4, r2, r5
        slw r2, r2, r6
        or r3, r4, r3
        or r3, r3, r2
        blr

b74ed07bfd Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

2926869b4a Fix a long-standing wart in the code generator: two-address instruction lowering 
actually *removes* one of the operands, instead of just assigning both operands
the same register.  This make reasoning about instructions unnecessarily complex,
because you need to know if you are before or after register allocation to match
up operand #'s with the target description file.

Changing this also gets rid of a bunch of hacky code in various places.

This patch also includes changes to fold loads into cmp/test instructions in
the X86 backend, along with a significant simplification to the X86 spill
folding code.

1911fd4f85 Completely rearchitect the interface between targets and the pass manager. 
This pass:

1. Splits TargetMachine into TargetMachine (generic targets, can be implemented
any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by
things using libcodegen and other support).
2. Instead of having each target fully populate the passmgr for file or JIT
   output, move all this to common code, and give targets hooks they can
   implement.
3. Commonalize the target population stuff between file emission and JIT
   emission.
4. All (native code) codegen stuff now happens in a FunctionPassManager, which
   paves the way for "fast -O0" stuff in the CFE later, and now LLC could
   lazily stream .bc files from disk to use less memory.
5. There are now many fewer #includes and the targets don't depend on the
   scalar xforms or libanalysis anymore (but codegen does).
6. Changing common code generator pass ordering stuff no longer requires
   touching all targets.
7. The JIT now has the option of "-fast" codegen or normal optimized codegen,
   which is now orthogonal to the fact that JIT'ing is being done.

1453de5aa9 Oops. Bad typo. Without the check of N1.hasOneUse() bad things can happen. 
Suppose the TokenFactor can reach the Op:

       [Load chain]
           ^
           |
         [Load]
         ^    ^
         |    |
        /      \-
       /         |
      /          [Op]
     /          ^ ^
     |        ..  |
     |       /    |
   [TokenFactor]  |
       ^          |
       |          |
        \        /
         \      /
         [Store]

If we move the Load below the TokenFactor, we would have created a cycle in
the DAG.

b9ca92661c Encode pc-relative conditional branch offset as pc+(num of bytes / 4). The 
asm printer will print it as offset*4. e.g. bne cr0, $+8.

The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.

bd564bfc63 Start eliminating temporary vectors used to create DAG nodes. Instead, pass 
in the start of an array and a count of operands where applicable.  In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap.  In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.

I updated a lot of code calling getNode that takes a vector, but ran out of
time.  The rest of the code should be updated, and these methods should be
removed.

We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.

It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

- Added synchronizeICache() to TargetJITInfo. It is called after each block
  of code is emitted to flush the icache. This ensures correct execution
  on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.

2a785500e0 bswapped load/store instructions are only availble in indexed addressing form. 
As such, use xoaddr (indexed only), not xaddr for address selection.

This fixes CodeGen/PowerPC/2006-07-19-stwbrx-crash.ll, a crash compiling lencod.
