Tobias Grosser 5416a0395f Adjust multidim test cases to not access out-of-bound memory
We do this currently only for test cases where we have integer offsets that
clearly access array dimensions out-of-bound.

-;   for (long i = 0; i < n; i++)
-;     for (long j = 0; j < m; j++)
-;       for (long k = 0; k < o; k++)
+;   for (long i = 0; i < n - 3; i++)
+;     for (long j = 4; j < m; j++)
+;       for (long k = 0; k < o - 7; k++)
 ;         A[i+3][j-4][k+7] = 1.0;

This will be helpful if we later want to simplify the access functions under the
assumption that they do not access memory out of bounds.

Fixes PR19932, but no test since I wasn't able to get any symptoms to appear, not even with valgrind and the testcase from the PR. It's clear what happened from inspection of the code.

Andrew Trick 8d2ee37f31 Add a subtarget hook: enablePostMachineScheduler.
As requested by AArch64 subtargets.

Note that this will have no effect until the
AArch64 target actually enables the pass like this:
substitutePass(&PostRASchedulerID, &PostMachineSchedulerID);

As soon as armv7 switches over, PostMachineScheduler will become the
default postRA scheduler, so this won't be necessary any more.
Targets using the old postRA schedule would then do:
substitutePass(&PostMachineSchedulerID, &PostRASchedulerID);

Andrew Trick 3ccf71d4d6 Move GenericScheduler and PostGenericScheduler into a header.
These were not exposed previously because I didn't want out-of-tree
targets to be too dependent on their internals. They can be reused for
a very wide variety of processors with casual scheduling needs without
exposing the classes by instead using hooks defined in
MachineSchedPolicy (we can add more if needed). When targets are more
aggressively tuned or want to provide custom heuristics, they can
define their own MachineSchedStrategy. I tend to think this is better
once you start customizing heuristics because you can copy over only
what you need. I don't think that layering heuristics generally works
well.

However, Arch64 targets now want to reuse the Generic scheduling logic
but also provide extensions. I don't see much harm in exposing the
Generic scheduling classes with a major caveat: these scheduling
strategies may change in the future without validating performance on
less mainstream processors. If you want to be immune from changes,
just define your own MachineSchedStrategy.

Alp Toker 1d257e1d0a Remove the last remaining llvm/Config/config.h includes
This corrects long-standing misuses of LLVM's internal config.h.

In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.

included by clang or other modules.

David Blaikie 19a8b90763 DebugInfo: Partial revert r209984 due to more cases where abstract DbgVariables do not have associated DIEs.
Along with a test case to demonstrate that due to inlining order there
are cases where abstract variable DIEs are not constructed since the
abstract subprogram was built due to a previous inlining that optimized
away those variables. This produces incorrect debug info (the 'missing'
abstract variable causes the inlined instance of that variable to be
emitted with a full description (name, line, file) rather than
referencing the abstract origin), but this commit at least ensures that
it doesn't crash...

Hans Wennborg e9af316423 Downgrade "definition of dllimport static field" error to warning for class templates (PR19902)
This allows us to compile the following kind of code, which occurs in MSVC
headers:

  template <typename> struct S {
    __declspec(dllimport) static int x;
  };
  template <typename T> int S<T>::x;

The definition works similarly to a dllimport inline function definition and
gets available_externally linkage.

Nick Kledzik cb9f890b77 [mach-o] Refactor sections -> atoms to be table driven.
Previously each section kind had its own code to loop over the section and
parse it into atoms.  This refactoring has two tables.  The first maps sections
to ContentType.  The second maps ContentType to information on how to find 
the atom boundaries.  

A few bugs in test cases were discovered as part of the refactoring.  
No change in functionality intended.

Sebastian Pop 422e33f363 record delinearization result and reuse it in polyhedral translation
Without this patch, the testcase would fail on the delinearization of the second
array:

; void foo(long n, long m, long o, double A[n][m][o]) {
;   for (long i = 0; i < n; i++)
;     for (long j = 0; j < m; j++)
;       for (long k = 0; k < o; k++) {
;         A[i+3][j-4][k+7] = 1.0;
;         A[i][0][k] = 2.0;
;       }
; }

; CHECK: [n, m, o] -> { Stmt_for_body6[i0, i1, i2] -> MemRef_A[3 + i0, -4 + i1, 7 + i2] };
; CHECK: [n, m, o] -> { Stmt_for_body6[i0, i1, i2] -> MemRef_A[i0, 0, i2] };

Here is the output of FileCheck on the testcase without this patch:

; CHECK: [n, m, o] -> { Stmt_for_body6[i0, i1, i2] -> MemRef_A[i0, 0, i2] };
         ^
<stdin>:26:2: note: possible intended match here
 [n, m, o] -> { Stmt_for_body6[i0, i1, i2] -> MemRef_A[o0] };
 ^

It is possible to find a good delinearization for A[i][0][k] only in the context
of the delinearization of both array accesses.

There are two ways to delinearize together all array subscripts touching the
same base address: either duplicate the code from scop detection to first gather
all array references and then run the delinearization; or as implemented in this
patch, use the same delinearization info that we computed during scop detection.
