Dimitry Andric 972e2c0cfb Avoid undefined behavior in LinkAllPasses.h
The LinkAllPasses.h file is included in several main programs, to force
a large number of passes to be linked in.  However, the ForcePassLinking
constructor uses undefined behavior, since it calls member functions on
`nullptr`, e.g.:

      ((llvm::Function*)nullptr)->viewCFGOnly();
      llvm::RGPassManager RGM;
      ((llvm::RegionPass*)nullptr)->runOnRegion((llvm::Region*)nullptr, RGM);

When the optimization level is -O2 or higher, the code below the first
nullptr dereference is optimized away, and replaced by `ud2` (on x86).

Therefore, the calls after that first dereference are never emitted.  In
my case, I noticed there was no call to `llvm::sys::RunningOnValgrind()`!

Replace instances of dereferencing `nullptr` with either objects on the
stack, or regular function calls.

Daniel Jasper 50780ce110 clang-format: [ObjC+JS] Allow bin-packing of array literals.
After reading the style guides again, they don't actually say how to
pack or not pack array literals. Based on some user reports, array
initializers can unnecessarily get quite long if they contain many
small elements. Array literals with trailing commas are still formatted
one per line so that users have a way to opt out of the packing.

Before:
  var array = [
    aaaaaa,
    aaaaaa,
    aaaaaa,
    aaaaaa,
    aaaaaa,

Tamas Berghammer 808ff186f6 Silence an incorrect dwarf parsing warning
We have a check what warns if the offset of a class member is greater
then or equal to the size of the class. The warning is valid in most
case but it is invalid when the last data member is a 0 size array
because in this case the member offset can be equal to the class size
(subject to alignment limitations).

This CL fixis LLDB to not print out a warning in this special case.

Artem Dergachev 73f018e381 [analyzer] Fix SVal/SymExpr/MemRegion class and enum names for consistency.
The purpose of these changes is to simplify introduction of definition files
for the three hierarchies.

1. For every sub-class C of these classes, its kind in the relevant enumeration
is changed to "CKind" (or C##Kind in preprocessor-ish terms), eg:

  MemRegionKind   -> MemRegionValKind
  RegionValueKind -> SymbolRegionValueKind
  CastSymbolKind  -> SymbolCastKind
  SymIntKind      -> SymIntExprKind

2. MemSpaceRegion used to be inconsistently used as both an abstract base and
a particular region. This region class is now an abstract base and no longer
occupies GenericMemSpaceRegionKind. Instead, a new class, CodeSpaceRegion,
is introduced for handling the unique use case for MemSpaceRegion as
"the generic memory space" (when it represents a memory space that holds all
executable code).

3. BEG_ prefixes in memory region kind ranges are renamed to BEGIN_ for
consisitency with symbol kind ranges.

4. FunctionTextRegion and BlockTextRegion are renamed to FunctionCodeRegion and
BlockCodeRegion, respectively. The term 'code' is less jargony than 'text' and
we already refer to BlockTextRegion as a 'code region' in BlockDataRegion.

Ulrich Weigand 46ff7ec317 [PowerPC] Fix large code model with the ELFv2 ABI
The global entry point prologue currently assumes that the TOC
associated with a function is less than 2GB away from the function
entry point.  This is always true when using the medium or small
code model, but may not be the case when using the large code model.

This patch adds a new variant of the ELFv2 global entry point prologue
that lifts the 2GB restriction when building with -mcmodel=large.
This works by emitting a quadword containing the distance from the
function entry point to its associated TOC immediately before the
entry point, and then using a prologue like:

ld r2,-8(r12)
add r2,r2,r12

Since creation of the entry point prologue is now split across two
separate routines (PPCLinuxAsmPrinter::EmitFunctionEntryLabel emits
the data word, PPCLinuxAsmPrinter::EmitFunctionBodyStart the prolog
code), I've switched to using named labels instead of just temporaries
to indicate the locations of the global and local entry points and the
new TOC offset data word.

These names are provided by new routines in PPCFunctionInfo modeled
after the existing PPCFunctionInfo::getPICOffsetSymbol.

Note that a corresponding change was committed to GCC here:
https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00355.html

binary appended at the beginning can assume where some inputs are.
