is that the unit test doesn't have IntTy equal to APInt, instead it uses a class
derived from APInt. When, as in these lines, an IntTy& reference is returned
but is assigned to an APInt&, the compiler destroys the temporary the IntTy& was
referring to, leaving the APInt& referring to garbage. This causes the unittest
to fail systematically on my machine; it can also be caught by running the test
under valgrind.

Some ELF relocations require adding the a value to the original contents of the object buffer at the specified location. In order to properly handle multiple applications of a relocation, the RuntimeDyld code should be grabbing the original value from the object buffer and writing a new value into the loaded section buffer. This patch changes the parameters passed to resolveRelocations to accommodate this need.

The new analysis is not yet ready for prime time. It has a *critical*
flawed assumption, and some troubling shortages of testing. Until it's
been hammered into better shape, let's stick with the working code. This
should be easy to revert itself when the analysis is ready.
Fixes PR14241, a miscompile of any memcpy-able loop which uses a pointer
as the induction mechanism. If you have been seeing miscompiles in this
revision range, you really want to test with this backed out. The
results of this miscompile are a bit subtle as they can lead to
downstream passes concluding things are impossible which are in fact
possible.
Thanks to David Blaikie for the majority of the reduction of this
miscompile. I'll be checking in the test case in a non-revert commit.

This allows parallel make for profiling code, without it there are file
collisions as each parallel run uses the default file name.
There is already code in the runtime library to specify the output file name
via the command line, but this only works for programs which already process
argc/argv. This patch builds on that support.

When target cost information is available, compute explicit costs of inserting and
extracting values from vectors. At this point, all costs are estimated using the
target information, and the chain-depth heuristic is not needed. As a result, it is now, by
default, disabled when using target costs.

the inttoptr instruction. The conceptual model here is that
'getAddressSpace' refers to the address space of this instruction's
type. It just happens that for GEPs, that is always the same as the
pointer operand's address space. We want both names so that access
patterns can be consistent between different instruction types.

These clarify that the methods called 'getPointerAddressSpace' apply to
the pointer *operand* of the instruction.

r165941: Resubmit the changes to llvm core to update the functions to
support different pointer sizes on a per address space basis.
Despite this commit log, this change primarily changed stuff outside of
VMCore, and those changes do not carry any tests for correctness (or
even plausibility), and we have consistently found questionable or flat
out incorrect cases in these changes. Most of them are probably correct,
but we need to devise a system that makes it more clear when we have
handled the address space concerns correctly, and ideally each pass that
gets updated would receive an accompanying test case that exercises that
pass specificaly w.r.t. alternate address spaces.
However, from this commit, I have retained the new C API entry points.
Those were an orthogonal change that probably should have been split
apart, but they seem entirely good.
In several places the changes were very obvious cleanups with no actual
multiple address space code added; these I have not reverted when
I spotted them.
In a few other places there were merge conflicts due to a cleaner
solution being implemented later, often not using address spaces at all.
In those cases, I've preserved the new code which isn't address space
dependent.
This is part of my ongoing effort to clean out the partial address space
code which carries high risk and low test coverage, and not likely to be
finished before the 3.2 release looms closer. Duncan and I would both
like to see the above issues addressed before we return to these
changes.
