Rafael Espindola ed1233e8a7 Call powerpc-darwin external tools with -arch ppc.
With this patch we call external tools for powerpc-darwin with "-arch ppc"
instead of "-arch powerpc", so as to be compatible with the cctools assembler
and ld64 linker.

Todd Fiala 0b903a0f69 Ensure the Host wait4 thread is able to show pid in thread name.
For hosts that cannot support long thread names, shrink the host
wait4 thread name so that it does not truncate the PID in the thread name.

Rafael Espindola b43d51de95 On MachO, don't put non-private constants in mergeable sections.
On MachO, putting a symbol that doesn't start with a 'L' or 'l' in one of the
__TEXT,__literal* sections prevents the linker from merging the context of the
section.

Since private GVs are the ones the get mangled to start with 'L' or 'l', we now
only put those on the __TEXT,__literal* sections.

Rui Ueyama 4a6ead7a9f [PECOFF] Another Win64 relocation bug fix

Sanjay Patel 81ecbb0737 Fix a logic bug in x86 vector codegen: sext (zext (x) ) != sext (x) (PR20472).
Remove a block of code from LowerSIGN_EXTEND_INREG() that was added with:
http://llvm.org/viewvc/llvm-project?view=revision&revision=177421

And caused:
http://llvm.org/bugs/show_bug.cgi?id=20472 (more analysis here)
http://llvm.org/bugs/show_bug.cgi?id=18054

The testcases confirm that we (1) don't remove a zext op that is necessary and (2) generate
a pmovz instead of punpck if SSE4.1 is available. Although pmovz is 1 byte longer, it allows 
folding of the load, and so saves 3 bytes overall.

Todd Fiala a9882cee50 llgs: add proper exec support for Linux.
This change:
* properly captures execs in NativeProcessLinux.
* clears out all non-main-thread thread metadata in NativeProcessLinux on exec.
* adds a DidExec() method to the NativeProcessProtocol delegate.
* clears out the auxv data cache when we exec (on Linux).

This is a small part of the llgs for local Linux debugging work going on here:
https://github.com/tfiala/lldb/tree/dev-llgs-local

I'm breaking it into small patches.

Oliver Stannard 28ee5d2e90 [ARM] Change default ABI for AArch32 to be "aapcs" (was "apcs-gnu")
The current default abi when no environment is given is "apcs-gnu",
which is obsolete. This patch changes the default to "aapcs". "aapcs" has both
hard- and soft-float variants, so the -mhard-float, -msoft-float and
-mfloat-abi= options now all behave as expected when no environment is
specified in the triple.

While writing this I also noticed that a preprocessor test claims to be
checking darwin, but is actually checking the defaults, which are
different for darwin.

`__clz` has already been implemented in the arm_acle.h header file. The rest are not supported yet. This patch completes ACLE data processing intrinsics.

Richard Trieu 8d08a2770e During cross field uninitialized checking, when processing an assignment,
don't mark the field as initialized until the next initializer instead of
instantly.  Since this checker is AST based, statements are processed in tree
order instead of following code flow.  This can result in different warnings
from just reordering the code.  Also changed to use one checker per constructor
instead of creating a new checker per field.

class T {
  int x, y;

  // Already warns
  T(bool b) : x(!b ? (1 + y) : (y = 5)) {}

  // New warning added here, previously (1 + y) comes after (y = 5) in the AST
  // preventing the warning.
  T(bool b) : x(b ? (y = 5) : (1 + y)) {}

Juergen Ributzka 31328168bb [FastISel] Undo phi node updates when falling-back to SelectionDAG.
The included test case would fail, because the MI PHI node would have two
operands from the same predecessor.

This problem occurs when a switch instruction couldn't be selected. This happens
always, because there is no default switch support for FastISel to begin with.

The problem was that FastISel would first add the operand to the PHI nodes and
then fall-back to SelectionDAG, which would then in turn add the same operands
to the PHI nodes again.

This fix removes these duplicate PHI node operands by reseting the
PHINodesToUpdate to its original state before FastISel tried to select the
instruction.

This fixes <rdar://problem/18155224>.
