0f66a91721 Add two new methods isTargetOpcode() which returns true if the node type 
is greater than the range of building selection dag node types, and
getTargetOpcode(), which returns the node opcode less the value of
isd::builtin_op_end, which specifies the end of the builtin types.

d5d0f9bd20 Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef) 
used to tack a register number onto the node.

Instead of doing this, make a new node, RegisterSDNode, which is a leaf
containing a register number.  These three operations just become normal
DAG nodes now, instead of requiring special handling.

Note that with this change, it is no longer correct to make illegal
CopyFromReg/CopyToReg nodes.  The legalizer will not touch them, and this
is bad, so don't do it. :)

e5d63829fd Some SELECT_CC cleanups: 
1. move assertions for node creation to getNode()
2. legalize the values returned in ExpandOp immediately
3. Move select_cc optimizations from SELECT's getNode() to SELECT_CC's,
   allowing them to be cleaned up significantly.

This paves the way to pick up additional optimizations on SELECT_CC, such
as sum-of-absolute-differences.

7cf7e3f33f Eliminate the SetCCSDNode in favor of a CondCodeSDNode class. This pulls the 
CC out of the SetCC operation, making SETCC a standard ternary operation and
CC's a standard DAG leaf.  This will make it possible for other node to use
CC's as operands in the future...

6a9746127a Like constants, globals on some platforms are GOT relative. This means they have to be allocated 
near the GOT, which new doesn't do.  So break out the allocate into a new function.

Also move GOT index handling into JITResolver.  This lets it update the mapping when a Lazy
function is JITed.  It doesn't managed the table, just the mapping.  Note that this is
still non-ideal, as any function that takes a function address should also take a GOT
index, but that is a lot of changes.  The relocation resolve process updates any GOT entry
it sees is out of date.

a0f5bf306c For: memory operations -> stores 
This is the first incremental patch to implement this feature. It adds no
functionality to LLVM but setup up the information needed from targets in
order to implement the optimization correctly. Each target needs to specify
the maximum number of store operations for conversion of the llvm.memset,
llvm.memcpy, and llvm.memmove intrinsics into a sequence of store operations.
The limit needs to be chosen at the threshold of performance for such an
optimization (generally smallish). The target also needs to specify whether
the target can support unaligned stores for multi-byte store operations.
This helps ensure the optimization doesn't generate code that will trap on
an alignment errors.
More patches to follow.

5f48ff7d1f Major refactor of the ELFWriter code. Instead of building up one big 
vector that represents the .o file at once, build up a vector for each
section of the .o file.  This is needed because the .o file writer needs
to be able to switch between sections as it emits them (e.g. switch
between the .text section and the .rel section when emitting code).

This patch has no functionality change.

ee448630bd For PR540: 
This patch completes the changes for making lli thread-safe. Here's the list
of changes:
* The Support/ThreadSupport* files were removed and replaced with the
  MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard.
  The implementation of MutexGuard.h is now based on sys::Mutex which hides
  its implementation and makes it unnecessary to have the -NoSupport.h and
  -PThreads.h versions of ThreadSupport.

* All places in ExecutionEngine that previously referred to "Mutex" now
  refer to sys::Mutex

* All places in ExecutionEngine that previously referred to "MutexLocker"
  now refer to MutexGuard (this is frivolous but I believe the technically
  correct name for such a class is "Guard" not a "Locker").

These changes passed all of llvm-test. All we need now are some test cases
that actually use multiple threads.

be used if (and only if) pthreads is not available.

fb5792f416 Implement Subtarget support 
Implement the X86 Subtarget.

This consolidates the checks for target triple, and setting options based
on target triple into one place.  This allows us to convert the asm printer
and isel over from being littered with "forDarwin", "forCygwin", etc. into
just having the appropriate flags for each subtarget feature controlling
the code for that feature.

This patch also implements indirect external and weak references in the
X86 pattern isel, for darwin.  Next up is to convert over the asm printers
to use this new interface.

a229c5cce7 Final Changes For PR495: 
This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:

makeReadable        -> makeReadableOnDisk
makeWriteable       -> makeWriteableOnDisk
makeExecutable      -> makeExecutableOnDisk
setStatusInfo       -> setStatusInfoOnDisk
createDirectory     -> createDirectoryOnDisk
createFile          -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy             -> eraseFromDisk
rename              -> renamePathOnDisk

These changes pass the Linux Deja Gnu tests.

dd04df0ec3 For PR495: 
Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:

appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set

Changes pass Dejagnu and llvm-test/SingleSource tests.

2d86ea21dd Implement Value* tracking for loads and stores in the selection DAG. This enables one to use alias analysis in the backends. 
(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.

when there are immediates, let's not worry about the memory overhead of

* add addU64Imm(uint64_t val) to machineinstrbuilder

(seriously: this seems required to support 64-bit immediates cleanly. if it
_really_ gets on your nerves, feel free to pull it out ;) )

855a519741 add support for prefix/suffix strings to go around GlobalValue(s) 
(which may or be function pointers) in the asmprinter. For the moment,
this changes nothing, except the IA64 backend which can use this to write:

  data8.ua  @fptr(blah__blah__mangled_function_name)

  (by setting FunctionAddrPrefix/Suffix to "@fptr(" / ")")

fc1b1dad88 Add ISD::UNDEF node 
Teach the SelectionDAG code how to expand and promote it
Have PPC32 LowerCallTo generate ISD::UNDEF for int arg regs used up by fp
  arguments, but not shadowing their value.  This allows us to do the right
  thing with both fixed and vararg floating point arguments.
