Summary:
We can't check the error message for this one because there's another lw/sw
available that covers a larger range. We therefore check the transition
between the two sizes.

It's a bug fix.
For rerolled loops SE trip count remains unchanged. It leads to incorrect work of the next passes.
My patch just resets SE info for rerolled loop forcing SE to re-evaluate it next time it requested.
I also added a verifier call in the exisitng test to be sure no invalid SE data remain. Without my fix this test would fail with -verify-scev.

When a tls access is optimized, a group of relocations is converted at a
time.
We were already skipping relocations that were optimized out in
relocate, but not in scanRelocs.
This is a small optimization. I got here while working on a patch that
will always keep scanRelocs and relocate in sync.
llvm-svn: 264048
R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX relocations were added in latest ABI:
https://github.com/hjl-tools/x86-psABI/wiki/x86-64-psABI-r249.pdf
They should be generated instead of R_X86_64_GOTPCREL for cases
when relaxation is possible. Currently this patch just process them in the
same way like R_X86_64_GOTPCREL. That should work for now
and we can implement relaxations later.
There is no testcases provided as I think there is no way to generate
such relocations using llvm-mc atm.

Summary: A checker (will be uploaded after this patch) needs to check implicit casts. Existing generic matcher "has" ignores implicit casts and parenthesized expressions and no specific matcher for matching return value expression preexisted. The patch adds such a matcher (hasReturnValue).

Some basic checks next to the implementation should futher lower the
possibility to introduce regressions. (Note that this would have catched
the ordering issue fixed in rL258866 and pointed to rL263940.)
The tests are implementation dependent in one point because they assume that
thread ids are assigned in ascending order. This is not defined by the standard
but currently ensured in libomp. We have to think about another way of ordering
the threads should this ever be subject to change...
Note that this isn't aiming at replacing the implementation independent
test-suite at https://github.com/OpenMPToolsInterface/ompt-test-suite!

IsExact shouldn't be set to true in WeakObjectProfileTy::getBaseInfo
when the receiver is a class because having a class as the receiver
doesn't guarantee that the Base is exact.

This reverts commit r264022.
This breaks the Window's bots which don't like that i'm calling ~Atom when
the this pointer is a sublcass of Atom.
Reverting for now until I try find a better fix. I tried using std::unique_ptr with
a custom deleter as a quick fix, but it didn't work well in the YAML parser.
llvm-svn: 264023
Currently each File contains an BumpPtrAllocator in which Atom's are
allocated. Some Atom's contain data structures like std::vector which
leak as we don't run ~Atom when they are BumpPtrAllocate'd.
Now each File actually owns its Atom's using an OwningAtomPtr. This
is analygous to std::unique_ptr and may be replaced by it if possible.
An Atom can therefore only be owned by a single File, so the Resolver now
moves them from one File to another. The MachOLinkingContext owns the File's
and so clears all the Atom's in ~MachOLinkingContext, then delete's all the
File's. This makes sure all Atom's have been destructed before any of the
BumpPtrAllocator's in which they run have gone away.
Should hopefully fix the remaining leaks. Will keep an eye on the bots to
make sure.

With this change, the class
struct A {
A(int _i);
~A();
int foo(double d);
double bar(A *a) { return 1.3; }
};
appears in the VS2015 Locals Window as
D 0x02dbb378 struct A
|- DeclKind CXXRecord
|- Members
|- [0] implicit struct A
|- [1] Constructor {A(int _i)}
|- [2] Destructor {~A()}
|- [3] Method {int foo(double d)}
|- [4] Method {double bar(struct A *)}
|- [Raw View] /* Other stuff */
Note that these changes only benefit VS2015 as
VS2013 does not have views and only displays the
struct name "A", but the change does no apparent
harm in VS2013, so is still a win.

Summary:
After this change, deopt operand bundles can be lowered directly by
SelectionDAG into STATEPOINT instructions (which are then lowered to a
call or sequence of nop, with an associated __llvm_stackmaps entry0.
This obviates the need to round-trip deoptimization state through
gc.statepoint via RewriteStatepointsForGC.

printf is an inline function in VS 2015, giving these tests an
unexpected extra point of coverage. This change works around that by
avoiding printf.

These functions cannot be implemented as atomicrmw or cmpxchg
instructions, so they are implemented as a call to the NVVM intrinsics

VS 2015 moved the priority of their exception filter initializer from
XIY to XCAA. We now set ours to XCAB, which makes it run after both CRT
versions but before user constructors, as it should.

failures remain.

There are some places in the CRT (such as mbctype) that directly call
_malloc_base. If you are incrementally linking a binary with ASan from

Retrying the link succeeds for some reason.

In trying to fix the leaks in the MachO lld codebase, we need to have
a better model for file and atom ownership. Having the context own
everything seems like the simplest model, so change all the passes to
allocate File's on the context instead of owning files as a member.

This patch adds a new set of substitutions to the lit run lines for order files and PGO generation which run the clang driver to get the cc1 command, then execute the cc1 command directly. This allows the scripts to bypass profiling the clang driver over and over again.
The approach in this patch was discussed via IRC with Sean Silvas.
Special thanks to Daniel Dunbar whose out-of-tree code I liberally plagiarized.

IRExecutionUnits contain code and data that persistent declarations can
depend on. In order to keep them alive and provide for lookup of these
symbols, we now allow any PersistentExpressionState to keep a list of
execution units. Then, when doing symbol lookup on behalf of an
expression, any IRExecutionUnit can consult the persistent expression
states on a particular Target to find the appropriate symbol.
