61ee100b97 raw_ostream::indent is used for PadToColumn which often prints more
than 16 spaces. Make the Spaces array wide enough to handle common cases.

32e1eef631 split raw_os_ostream out to its own header and implementation file. This
means that raw_ostream no longer has to #include <iosfwd>.  Nothing in llvm
should use raw_os_ostream.h, but llvm-gcc and some unit tests do.

23132b188b prune the #includes in raw_ostream.h by moving a
member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

74382b7c69 Prune #includes from llvm/Linker.h and llvm/System/Path.h,
forcing them down into various .cpp files.

This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
   for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
   clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
   instead.
4. Weans llvm-db off <iostream>

sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

9441cfe488 Fix off-by-one in llvm::Format::print.
- This also shortens the Format.h implementation, and uses the print buffer
   fully (it was wasting a character).

 - This manifested as llvm-test failures, because one side effect was that
   raw_ostream would write garbage '\x00' values into the output stream if it
   happened that the string was at the end of the buffer. This meant that grep
   would report 'Binary file matches', which meant the silly pattern matching
   llvm-test eventually does would fail. Cute. :)

17e9edc4a7 Change raw_fd_ostream to take flags as an optional bitmask
instead of as two bools.  Use this to add a F_Append flag
which has the obvious behavior.

Other unrelated changes conflated into this patch:

1. REmove EH stuff from llvm-dis and llvm-as, the try blocks
   are dead.
2. Simplify the filename inference code in llvm-as/llvm-dis,
   because raw_fd_ostream does the right thing with '-'.
3. Switch machine verifier to use raw_ostream instead of ostream
   (Which is the thing that needed append in the first place).

d14787e497 Change raw_svector_ostream to reserve the input buffer if necessary, Ted was
right.
 - This class turns out to be much more convenient to use if we do this; clients
   can make sure the buffer is always big enough if they care (since our current
   idiom tends to be to use a SmallString<256> for the input to this we should
   generally be avoiding an unnecessary malloc).

Also, add a convenience raw_svector_ostream::str method which flushes the buffer
and returns a StringRef for the vector contents.

- Kill off begin(), end(), and iterator. It isn't clear what these

   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.

3c2d4bf97f Pass target triple string in to TargetMachine constructor.
This is not just a matter of passing in the target triple from the module;
currently backends are making decisions based on the build and host
architecture. The goal is to migrate to making these decisions based off of the
triple (in conjunction with the feature string). Thus most clients pass in the
target triple, or the host triple if that is empty.

This has one important change in the way behavior of the JIT and llc.

For the JIT, it was previously selecting the Target based on the host
(naturally), but it was setting the target machine features based on the triple
from the module. Now it is setting the target machine features based on the
triple of the host.

For LLC, -march was previously only used to select the target, the target
machine features were initialized from the module's triple (which may have been
empty). Now the target triple is taken from the module, or the host's triple is
used if that is empty. Then the triple is adjusted to match -march.

The take away is that -march for llc is now used in conjunction with the host
triple to initialize the subtarget. If users want more deterministic behavior
from llc, they should use -mtriple, or set the triple in the input module.

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this

95eb3ad353 Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

e87b2abe91 Change raw_ostream so that it doesn't call llvm_report_error
immediately on every output error. Instead, add a flag to
raw_ostream, and set the flag whenever an error is detected.

The flag can be queried and cleared from the public API. This
gives applications more flexibility to handling errors in
application-specific ways.

If the flag is not cleared when the raw_ostream is destructed,
llvm_report_error is called from the destructor. This ensures
that errors are not implicitly silenced, and provides
convenient default behavior for tools like llc and opt.
Clients wishing to avoid llvm_report_error calls from
raw_ostream should check for errors and clear the error flag.

bb06129140 Add new TargetRegistry.
Targets implement a single global Target structure which will live in a new
<Target>/TargetInfo library; this will be present in any image which the target
is usable in.
 - Optional target specific classes can then be registered and attached to the
   Target description.

 - Registration for normal Targets will be done via the initialization functions
   instead of using static constructors.

 - This allows clients to use a single interface to obtain target data, without
   requiring the code generator be linked in. It also provides a natural
   extension point for adding new optional target data (assembler parser,
   disassembler, etc.).

 - This also provides a new entry point for obtaining a target for a particular
   triple (without a module).

 - Not yet used, however this should eventually replace the TargetMachineRegistry.

1b25cb2416 Fix internal representation of fp80 to be the
same as a normal i80 {low64, high16} rather
than its own {high64, low16}.  A depressing number
of places know about this; I think I got them all.
Bitcode readers and writers convert back to the old
form to avoid breaking compatibility.

cf2a2c6a26 raw_ostream: Lift out flush_nonempty.
- Flush a known non-empty buffers; enforces the interface to
   flush_impl and kills off HandleFlush (which I saw no reason to be
   an inline method, Chris?).

 - Clarify invariant that flush_impl is only called with OutBufCur >
   OutBufStart.

 - This also cleary collects all places where we have to deal with the
   buffer possibly not existing.

 - A few more comments and fixing the unbuffered behavior remain in
   this commit sequence.

d52ec65b6d Fix a hashing bug in APInt. A certain pathological testcase (too
large for the testsuite) took over six minutes to compile on my Mac.
The patched LLVM-GCC compiles that testcase in three seconds (GCC
takes less than one second).  This hash function is more complex
(about 35 instructions on x86) than what Chris wanted, but I expect it
will be well-behaved with arbitrary inputs.

Thank you to everyone who responded to my previous request for advice.

feels a kinship to machine stacks that grow down.  Now we get
stuff like this:

13319ceffd The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF.
Add support for two additional DWARF attributes to encode Objective-C runtime version number.

aff9c270de Unbreak the build on win32.
Cleanup some warning.

Remark: when struct/class are declared differently than they are defined, this make problem for VC++ since it seems to mangle class differently that struct. These error are very hard to understand and find. So please, try to keep your definition/declaration in sync.

Only tested with VS2008. hope it does not break anything. feel free to revert.
