a31708e6b3 Change ConstantPoolSDNode to actually hold the Constant itself instead of 
putting it into the constant pool.  This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.

a1470f81ae For PR616: 
These patches make threading optional in LLVM. The configuration scripts are now
modified to accept a --disable-threads switch. If this is used, the Mutex class
will be implemented with all functions as no-op. Furthermore, linking against
libpthread will not be done. Finally, the ParallelJIT example needs libpthread
so its makefile was changed to always add -lpthread to the link line.

180f2050d0 Keep the killed/dead sets sorted, so that "KillsRegister" can do a quick 
binary search to test for membership.  This speeds up LLC a bit more on KC++,
e.g. on itanium from 16.6974s to 14.8272s, PPC from 11.4926s to 10.7089s and
X86 from 10.8128s to 9.7943s, with no difference in generated code (like all
of the RA patches).

With these changes, isel is the slowest pass for PPC/X86, but linscan+live
intervals is still > 50% of the compile time for itanium.  More work could
be done, but this is the last for now.

3bb878f134 Change live variables from using multimaps to using maps of vectors and 
rearrange some of the accessors to be more efficient.

This makes it much more efficient to iterate over all of the things with the
same value.  This speeds up liveintervals analysis from 8.63s to 3.79s with
a release build of llc on kc++ with -march=ia64.  This also speeds up live
var from 1.66s -> 0.87s as well, reducing total llc time from 20.1s->15.2s.

This also speeds up other targets slightly, e.g. llc time on X86 from 16.84
-> 16.45s, and PPC from 17.64->17.03s.

3b7e157005 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. :)

02e0c80ecb 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.

40c5ebe4eb 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.

40fbf63df8 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.

Reid Spencer
78910545f0 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.

5f037ea395 For PR540: 
Add a Mutex class for thread synchronization in a platform-independent way.
The current implementation only supports pthreads. Win32 use of Critical
Sections will be added later. The design permits other threading models to
be used if (and only if) pthreads is not available.

626fb671c8 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.

04d734c2f6 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.

5534b2d505 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.

a416f4bbf3 * store immediate values as int64_t, not int. come on, we should be happy 
when there are immediates, let's not worry about the memory overhead of
this :)

* 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 ;) )

9b289130f7 Eliminate the explicit opcode field in ConstantExpr, using the SubclassData 
field to hold it instead.  This shrinks memory usage for 176.gcc from
57628728 to 57598144 bytes, a small reduction of about 30K.

7eb45f89a5 Eliminate the explicit volatile fields in LoadInst and StoreInst. This shrinks 
LoadInst from 60 -> 56 bytes and StoreInst from 76 -> 72 bytes.

Note however, that this doesn't actually save any memory on common systems
where 'malloc' returns 8-byte aligned memory, as the saved space is replaced
by useless alignment padding.  :(

fdbedbbb45 Switch from using an ilist for uses to using a custom doubly linked list. 
This list does not provide the ability to go backwards in the list (its
more of an unordered collection, stored in the shape of a list).

This change means that use iterators are now only forward iterators, not
bidirectional.

This improves the memory usage of use lists from '5 + 4*#use' per value to
'1 + 4*#use'.  While it would be better to reduce the multiplied factor,
I'm not smart enough to do so.  This list also has slightly more efficient
operators for manipulating list nodes (a few less loads/stores), due to not
needing to be able to iterate backwards through the list.

This change reduces the memory footprint required to hold 176.gcc from
66.025M -> 57.687M, a 14% reduction.  It also speeds up the compiler,
7.73% in the case of bytecode loading alone (release build loading 176.gcc).

ee6bc42f3e * Make some methods more const correct. 
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists.
  This makes many operations on these lists much more natural, and avoids
  *exteremely* expensive copying of DSCallSites (e.g. moving nodes around
  between lists, erasing a node from not the end of the vector, etc).

With a profile build of analyze, this speeds up BU DS from 25.14s to
12.59s on 176.gcc.  I expect that it would help TD even more, but I don't
have data for it.

This effectively eliminates removeIdenticalCalls and children from the
profile, going from 6.53 to 0.27s.

e9c443b500 Adjust to ilist changes. 
Based on the ilist changes avoid allocating an entire Use object for the
end of the Use chain.  This saves 8 bytes of memory for each Value allocated
in the program.  For 176.gcc, this reduces us from 69.5M -> 66.0M, a 5.3%
memory savings.

3f035ee52d There is no reason to include ostream here, include iosfwd instead. 
This file was schizophrenic when it came to representing sizes.  In some
cases it represented them as 'unsigneds', which are not enough for 64-bit
hosts.  In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.

This patch unifies all of the sizes to use size_t instead.

c6c1106909 Instead of storing operands as std::vector<Use>, just maintain a pointer 
and num operands in the User class.  this allows us to embed the operands
directly in the subclasses if possible.  For example, for binary operators
we store the two operands in the derived class.

The has several effects:
  1. it improves locality because the operands and instruction are together
  2. it makes accesses to operands faster (one less load) if you access them
     through the derived class pointer.  For example this:

Value *GetBinaryOperatorOp(BinaryOperator *I, int i) {
  return I->getOperand(i);
}

Was compiled to:

_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
        movl    4(%esp), %edx
        movl    8(%esp), %eax
        sall    $4, %eax
        movl    24(%edx), %ecx
        addl    %ecx, %eax
        movl    (%eax), %eax
        ret

and is now compiled to:

_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
        movl    8(%esp), %eax
        movl    4(%esp), %edx
        sall    $4, %eax
        addl    %edx, %eax
        movl    44(%eax), %eax
        ret

Accesses through "Instruction*" are unmodified.

   3. This reduces memory consumption (by about 3%) by eliminating 1 word of
      vector overhead and a malloc header on a seperate object.
   4. This speeds up gccas about 10% (both debug and release builds) on
      large things (such as 176.gcc).  For example, it takes a debug build
      from 172.9 -> 155.6s and a release gccas from 67.7 -> 61.8s

766ad3378c This giant patch speeds up Type::isSized(). Before, this would have to search 
large nested types over and over again to determine if they are sized or not.
Now, isSized() is able to make snap decisions about all concrete types, which
are a common occurance (and includes all primitives).

On 177.mesa, this speeds up DSE from 39.5s -> 21.3s and GCSE from
13.2s -> 11.3s, reducing gccas time from 80s -> 61s (this is a debug build).

DSE and GCSE are still too slow on this testcase, but this is a simple
improvement.
