I made my best guess at the Makefile, since I don't have a make build.
I'm not sure if it should be valid to add an empty list of things, but
it seemed the sort of degenerate case.

This constructor is more efficient for symbols that have already been emitted,
since it avoids the construction/execution of a std::function.
Update the ObjectLinkingLayer to use this new constructor where possible.

This patch replaces most of the Orc indirection utils API with a new class:
JITCompileCallbackManager, which creates and manages JIT callbacks.
Exposing this functionality directly allows the user to create callbacks that
are associated with user supplied compilation actions. For example, you can
create a callback to lazyily IR-gen something from an AST. (A kaleidoscope
example demonstrating this will be committed shortly).
This patch also refactors the CompileOnDemand layer to use the
JITCompileCallbackManager API.

and LazyEmittingLayer of Orc.
This method allows you to immediately emit and finalize a module. It is required
by an upcoming refactor of the indirection utils and the compile-on-demand
layer.
I've filed http://llvm.org/PR22608 to write unit tests for this and other Orc
APIs.

LLVM's include tree and the use of using declarations to hide the
'legacy' namespace for the old pass manager.
This undoes the primary modules-hostile change I made to keep
out-of-tree targets building. I sent an email inquiring about whether
this would be reasonable to do at this phase and people seemed fine with
it, so making it a reality. This should allow us to start bootstrapping
with modules to a certain extent along with making it easier to mix and
match headers in general.
The updates to any code for users of LLVM are very mechanical. Switch
from including "llvm/PassManager.h" to "llvm/IR/LegacyPassManager.h".
Qualify the types which now produce compile errors with "legacy::". The
most common ones are "PassManager", "PassManagerBase", and
"FunctionPassManager".

std::strings) rather than StringRefs in JITSymbol get-address lambda.
Capturing a StringRef by-value is still effectively capturing a reference, which
is no good here because the referenced string may be gone by the time the lambda
is being evaluated the original value may be gone. Make sure to capture a
std::string instead.
No test case: This bug doesn't manifest under OrcMCJITReplacement, since it
keeps IR modules (from which the StringRefs are sourced) alive permanently.

As far as I can tell r228568 was the right workaround, and r228567 was
unnecessary. If reverting this causes problems on the bots I'll reinstate it.

Apparently gcc-4.7.2 is touchy about 'this' appearing in a lambda capture list
along with other captures. I've rewritten my captures to try to avoid the issue.

This patch refactors a key piece of the Orc APIs: It removes the
*::getSymbolAddress and *::lookupSymbolAddressIn methods, which returned target
addresses (uint64_ts), and replaces them with *::findSymbol and *::findSymbolIn
respectively, which return instances of the new JITSymbol type. Unlike the old
methods, calling findSymbol or findSymbolIn does not cause the symbol to be
immediately materialized when found. Instead, the symbol will be materialized
if/when the getAddress method is called on the returned JITSymbol. This allows
us to query for the existence of symbols without actually materializing them. In
the future I expect more information to be attached to the JITSymbol class, for
example whether the returned symbol is a weak or strong definition. This will
allow us to properly handle weak symbols and multiple definitions.

This was a trivial think-o, but it's in a method of a templated class
and doesn't have any callers yet, so the compiler let it pass. I hope
to add a unit test to cover this soon.

finalization time.
As currently implemented, RuntimeDyldELF requires the original object
file to be avaible when relocations are being resolved. This patch
ensures that the ObjectLinkingLayer preserves it until then. In the
future RuntimeDyldELF should be rewritten to remove this requirement, at
which point this patch can be reverted.
Regression test cases for Orc (which include coverage of this bug) will
be committed shortly.

These constructors were causing trouble for MSVC and older GCCs. This should
fix more of the build failures from r226940.

This patch adds a new set of JIT APIs to LLVM. The aim of these new APIs is to
cleanly support a wider range of JIT use cases in LLVM, and encourage the
development and contribution of re-usable infrastructure for LLVM JIT use-cases.
These APIs are intended to live alongside the MCJIT APIs, and should not affect
existing clients.
Included in this patch:
1) New headers in include/llvm/ExecutionEngine/Orc that provide a set of
components for building JIT infrastructure.
Implementation code for these headers lives in lib/ExecutionEngine/Orc.
2) A prototype re-implementation of MCJIT (OrcMCJITReplacement) built out of the
new components.
3) Minor changes to RTDyldMemoryManager needed to support the new components.
These changes should not impact existing clients.
4) A new flag for lli, -use-orcmcjit, which will cause lli to use the
OrcMCJITReplacement class as its underlying execution engine, rather than
MCJIT itself.
Tests to follow shortly.
Special thanks to Michael Ilseman, Pete Cooper, David Blaikie, Eric Christopher,
Justin Bogner, and Jim Grosbach for extensive feedback and discussion.
