d4347e1af9 Define a new intrinsic, @llvm.debugger. It will be similar to __builtin_trap(),
but it generates int3 on x86 instead of ud2.

30759542aa change the objectsize intrinsic signature: add a 3rd parameter to denote the maximum runtime performance penalty that the user is willing to accept.
This commit only adds the parameter. Code taking advantage of it will follow.

a5d2435409 [docs] Remove POD based man page docs (and build system support).
- Currently this leaves us with less build system support (e.g., installing man pages) for the docs than is desired. I'm working on fixing this, but it may take a while. If someone finds this particularly egregious let me know and I will prioritize it.

3c00db75e1 [CMake] Restructure how Clang, Polly and other external projects get included.
While making lld build under the tools directory I decided to refactor how this
works.

There is now a macro, add_llvm_external_project, which takes the name of the
expected subdirectory. This sets up two CMake options.

 * LLVM_EXTERNAL_${NAME}_SOURCE_DIR
     This is the path to the source. It defaults to
     ${CMAKE_CURRENT_SOURCE_DIR}/${name}.
 * LLVM_EXTERNAL_${NAME}_BUILD
     Enable and disable building the tool as part of LLVM.

I chose LLVM_EXTERNAL_${NAME} as a prefix so they all show up together in the
GUI.

76271a3366 First implementation of:
- FlatArrayMap. Very simple map container that uses flat array inside.
- MultiImplMap. Map container interface, that has two modes, one for small amount of elements and one for big amount.
- SmallMap. SmallMap is DenseMap compatible MultiImplMap. It uses FlatArrayMap for small mode, and DenseMap for big mode. 

Also added unittests for new classes and update for ProgrammersManual.
For more details about new classes see ProgrammersManual and comments in sourcecode.

75338097c7 Remove llvm-ld and llvm-stub (which is only used by llvm-ld).
llvm-ld is no longer useful and causes confusion and so it is being removed.

* Does not work very well on Windows because it must call a gcc like driver to
  assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
  ld, or fully replaced by Clang.

I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.

8883c43ddc Make it possible to indicate relaxed floating point requirements at the IR level
through the use of 'fpmath' metadata.  Currently this only provides a 'fpaccuracy'
value, which may be a number in ULPs or the keyword 'fast', however the intent is
that this will be extended with additional information about NaN's, infinities
etc later.  No optimizations have been hooked up to this so far.

5e5c5f8259 Rename "fpaccuracy" metadata to the more generic "fpmath". That's because I'm
thinking of generalizing it to be able to specify other freedoms beyond accuracy
(such as that NaN's don't have to be respected).  I'd like the 3.1 release (the
first one with this metadata) to have the more generic name already rather than
having to auto-upgrade it in 3.2.

cc85160672 Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnu
* Removed test/lib/llvm.exp - it is no longer needed 
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
  left in the test suite so this code is no longer required. test/lit.cfg is
  now much shorter and clearer 
* Removed a lot of duplicate code in lit.local.cfg files that need access to
  the root configuration, by adding a "root" attribute to the TestingConfig
  object. This attribute is dynamically computed to provide the same
  information as was previously provided by the custom getRoot functions. 
* Documented the config.root attribute in docs/CommandGuide/lit.pod

cebb4ee93a Add Foreach Loop
Add some data structures to represent for loops.  These will be
referenced during object processing to do any needed iteration and
instantiation.

Add foreach keyword support to the lexer.

Add a mode to indicate that we're parsing a foreach loop.  This allows
the value parser to early-out when processing the foreach value list.

Add a routine to parse foreach iteration declarations.  This is
separate from ParseDeclaration because the type of the named value
(the iterator) doesn't match the type of the initializer value (the
value list).  It also needs to add two values to the foreach record:
the iterator and the value list.

Add parsing support for foreach.

Add the code to process foreach loops and create defs based
on iterator values.

Allow foreach loops to be matched at the top level.

When parsing an IDValue check if it is a foreach loop iterator for one
of the active loops.  If so, return a VarInit for it.

Add Emacs keyword support for foreach.

Add VIM keyword support for foreach.

Add tests to check foreach operation.

Add TableGen documentation for foreach.

Support foreach with multiple objects.

Support non-braced foreach body with one object.

Do not require types for the foreach declaration.  Assume the iterator
type from the iteration list element type.

62588622d4 Add a Briggs and Torczon sparse set implementation.
For objects that can be identified by small unsigned keys, SparseSet
provides constant time clear() and fast deterministic iteration. Insert,
erase, and find operations are typically faster than hash tables.

SparseSet is useful for keeping information about physical registers,
virtual registers, or numbered basic blocks.

164b86b439 Extend Attributes to 64 bits
Problem: LLVM needs more function attributes than currently available (32 bits).
One such proposed attribute is "address_safety", which shows that a function is being checked for address safety (by AddressSanitizer, SAFECode, etc).

Solution:
- extend the Attributes from 32 bits to 64-bits
- wrap the object into a class so that unsigned is never erroneously used instead
- change "unsigned" to "Attributes" throughout the code, including one place in clang.
- the class has no "operator uint64 ()", but it has "uint64_t Raw() " to support packing/unpacking.
- the class has "safe operator bool()" to support the common idiom:  if (Attributes attr = getAttrs()) useAttrs(attr);
- The CTOR from uint64_t is marked explicit, so I had to add a few explicit CTOR calls
- Add the new attribute "address_safety". Doing it in the same commit to check that attributes beyond first 32 bits actually work.
- Some of the functions from the Attribute namespace are worth moving inside the class, but I'd prefer to have it as a separate commit.

Tested:
"make check" on Linux (32-bit and 64-bit) and Mac (10.6)
built/run spec CPU 2006 on Linux with clang -O2.


This change will break clang build in lib/CodeGen/CGCall.cpp.
The following patch will fix it.

7739cad69d Add a new kind of MachineOperand: MO_RegisterMask.
Register masks will be used as a compact representation of large clobber
lists.  Currently, an x86 call instruction has some 40 operands
representing call-clobbered registers.  That's more than 1kB of useless
operands per call site.

A register mask operand references a bit mask of call-preserved
registers, everything else is clobbered.  The bit mask will typically
come from TargetRegisterInfo::getCallPreservedMask().

By abandoning ImplicitDefs for call-clobbered registers, it also becomes
possible to share call instruction descriptions between calling
conventions, and we can get rid of the WINCALL* instructions.

This patch introduces the new operand kind.  Future patches will add
RegMask support to target-independent passes before finally the fixed
clobber lists can be removed from call instruction descriptions.

d9e5c764bf Freeze reserved registers before starting register allocation.
The register allocators don't currently support adding reserved
registers while they are running.  Extend the MRI API to keep track of
the set of reserved registers when register allocation started.

Target hooks like hasFP() and needsStackRealignment() can look at this
set to avoid reserving more registers during register allocation.

-fplugin-arg-dragonegg-enable-gcc-optzns, though it usually isn't
a win.

cc966de237 Add a link from the LLVM release notes to the Clang release notes.
I suspect we could profitably remove/move some of the bullet points
under Clang here to the Clang notes in order to keep things clean on
both sides. Unless I hear objections I'll start doing that once folks
have read over the Clang notes a bit.
