Michael Liao 62ebfd8786 Fix PR16360
When (srl (anyextend x), c) is folded into (anyextend (srl x, c)), the
high bits are not cleared. Add 'and' to clear off them.

Andrew Trick 6b9c49a275 Handle more cases in LiveRangeEdit::eliminateDeadDefs.
Live intervals for dead physregs may be created during coalescing. We
need to update these in the event that their instruction goes away.

crash.ll is the unit test that catches it when MI sched is enabled on
X86.

Andrew Trick 75961ecc1a Modify the -join-globalcopies option (off by default).
Always coalesce in forward order to propagate rematerialization.
I'm fixing this option so I can enable it by default soon.

Jordan Rose e83cb0922b Revert "[analyzer] Handle zeroing CXXConstructExprs."
Per review from Anna, this really should have been two commits, and besides
it's causing problems on our internal buildbot. Reverting until these have
been worked out.

Ulrich Weigand 91add7dfbf [PowerPC] Support R_PPC_REL16 family of relocations
The GNU assembler supports (as extension to the ABI) use of PC-relative
relocations in half16 fields, which allows writing code like:

  li 1, base-.

This patch adds support for those relocation types in the assembler.

Ulrich Weigand 876a0d0133 [PowerPC] Support various tls-related modifiers
The current code base only supports the minimum set of tls-related
relocations and @modifiers that are necessary to support compiler-
generated code.  This patch extends this to the full set defined
in the ABI (and supported by the GNU assembler) for the benefit
of the assembler parser.

Ulrich Weigand e67c565dc1 [PowerPC] Support @h modifier
This adds necessary infrastructure to support the @h modifier.
Note that all required relocation types were already present
(and unused).

This patch provides support for using @h in the assembler;
it would also be possible to now use this feature in code
generated by the compiler, but this is not done yet.

Ulrich Weigand d51c09f5d9 [PowerPC] Rename some more VK_PPC_ enums
This renames more VK_PPC_ enums, to make them more closely reflect
the @modifier string they represent.  This also prepares for adding
a bunch of new VK_PPC_ enums in upcoming patches.

For consistency, some MO_ flags related to VK_PPC_ enums are
likewise renamed.

No change in behaviour.

Reid Kleckner 23f4c4b64f [ms-cxxabi] Destroy temporary record arguments in the callee
Itanium destroys them in the caller at the end of the full expression,
but MSVC destroys them in the callee.  This is further complicated by
the need to emit EH-only destructor cleanups in the caller.

This should help clang compile MSVC's debug iterators more correctly.
There is still an outstanding issue in PR5064 of a memcpy emitted by the
LLVM backend, which is not correct for C++ records.

Fixes PR16226.

The output can be in different orders, which breaks the test in some

difference is. This fixes our internal build. If it is not the right
solution, feel free to roll back.

Tobias Grosser edab1359a0 Use isl_val instead of isl_int in the core of Polly
isl recently introduced isl_val as an abstract interface to represent arbitrary
precision numbers. This interface superseeds the old isl_int interface. In
contrast to the old interface which implemented arbitrary precision arithmetic
using macros that forward to the gmp library, the new library hides the math
library implementation in isl. This allows us to switch the math library used by
isl without affecting users such as Polly.

David Blaikie 512b3f22bb DebugInfo: When asm printing include a '[def]' tag for tag decls that are definitions (& rename the 'fwd' tag to 'decl' for clarity)

David Blaikie 03039fe9ba DebugInfo: handle the DI asm printing change to reword '[fwd]' as '[decl]' and add '[def]' for non-decl tag types
This is to make test cases looking for definitions more legible by
making the definition explicit rather than just the absence of '[fwd]'.
This allowed the debug-info-record tests to be rephrased - and in the
interests of reducing the number of individual test cases/invocations we
have, I merged them into one file, separated them with namespaces (&
then moved them to C++ because namespaces are great). If they need to
remain 'C' only tests, they can be moved back. (I didn't group them with
'debug-info-class.cpp' because these tests only apply to
-fno-limit-debug-info)

I removed the pieces of code that would cause these tests to pass under
-flimit-debug-info to ensure the tests remain relevant to their fixes
should we ever improve -flimit-debug-info to catch that kind of code.

This commit is version locked with the corresponding change to
DebugInfo.h in LLVM. Except some transient buildbot fallout.
