3ed469ccd7 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

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.

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.

a69571c799 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.

b0636041c8 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.

2b4ea795a2 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

64aa0ea4e9 this is a hack, which may or may not hang around. In short: 
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?

f2db9b88da DAG->DAG instruction selection for ia64! "hello world" works, not much else. 
use -enable-ia64-dag-isel to turn this on

TODO: delete lowering stuff from the pattern isel
    : get operations on predicate bits working
    : get other bits of pseudocode going
    : use sampo's mulh/mull-using divide-by-constant magic
    : *so* many patterns ("extr", "tbit" and "dep" will be fun :)
    : add FP
    : add a JIT!
    : get it working 100%

in short: this'll be happier in a couple of weeks, but it's here now so
the tester can make me feel guilty sooner.

OTHER: there are a couple of fixes to the pattern isel, in particular
making the linker happy with big blobs of fun like pypy.

cheaper in a release build).

e0fe225e89 Make several cleanups to Andrews varargs change: 
1. Pass Value*'s into lowering methods so that the proper pointers can be
   added to load/stores from the valist
2. Intrinsics that return void should only return a token chain, not a token
   chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.
4. Now that we have Value*'s available in the lowering methods, pass them
   into any load/stores from the valist that are emitted

(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.

b2322561cb * Add code to reduce multiplies by constant integers to shifts, adds and 
subtracts. This is a very rough and nasty implementation of Lefevre's
  "pattern finding" algorithm. With a few small changes though, it should
  end up beating most other methods in common use, regardless of the size
  of the constant (currently, it's often one or two shifts worse)

  TODO: rewrite it so it's not hideously ugly (this is a translation from
        perl, which doesn't help ;)
        bypass most of it for multiplies by 2^n+1
	(eventually) teach it that some combinations of shift+add are
	cheaper than others (e.g. shladd on ia64, scaled adds on alpha)
	get it to try multiple booth encodings in search of the cheapest
	routine
	make it work for negative constants

  This is hacked up as a DAG->DAG transform, so once I clean it up I hope
  it'll be pulled out of here and put somewhere else. The only thing backends
  should really have to worry about for now is where to draw the line
  between using this code vs. going ahead and doing an integer multiply
  anyway.

1ce0c015ad print negative 64 bit immediates as negative numbers, makes things a little 
easier on the eyes, not that numbers like 18446744073709541376 are bad or
anything

ed09502a0b * add the shladd instruction 
* fold left shifts of 1, 2, 3 or 4 bits into adds

  This doesn't save much now, but should get a serious workout once
  multiplies by constants get converted to shift/add/sub sequences.
  Hold on! :)

c02780eed1 * if ANDing with a constant of the form: 
0x00000..00FFF..FF
      ^      ^
      ^      ^
    any number of
    0's followed by
    some number of
    1's

    then we use dep.z to just paste zeros over the input. For the special
    cases where this is zxt1/zxt2/zxt4, we use those instructions instead,
    because we're all about readability!!!
    that's what it's about!! readability!

  *twitch* ;D

6ac614a4f2 Remove special handling of ZERO_EXTEND_INREG. This pessimizes code, causing 
things like this:

       mov r9 = 65535;;
       and r8 = r8, r9;;

To be emitted instead of:

        zxt2 r8 = r8;;

To get this back, the selector for ISD::AND should recognize this case.

e8fd25f5c5 * OK, after changing to use liveIn/liveOut instead of IDEFs, 
to avoid redundant mov out3=r44 type instructions, we need to
tell the register allocator the truth about out? registers.

FIXME: unfortunately, since the list of allocatable registers is immutable,
we can't simply 'delete r127' from the allocation order, say, if 'out0' is
used. The only correct thing we can do is have a linear order of regs:

out7, out6 ... out2, out1, out0, r32, r33, r34 ... r126, r127

and slide a 'window' of 96 registers along this line, depending on how many
of the out? regs a function actually uses. The only downside of this is
that the out? registers will be allocated _first_, which makes the
resulting assembly ugly. :( Note this in the README. Hope this gets fixed
soon. :) (note the 3rd person speech there)
