John McCall 611d9b6659 Ensure that debugger calls to signature-less functions default to
passing arguments in the fixed style.

We have an abstraction for deciding this, but it's (1) deep in
IR-generation, (2) necessarily tied to exact argument lists, and
(3) triggered by unprototyped function types, which we can't
legitimately make in C++ mode.  So this solution, wherein Sema
rewrites the function type to an exact prototype but leaves the
variadic bit enabled so as to request x86-64-like platforms to
pass the extra variadic info, is very much a hack, but it's one
that works in practice on the platforms that LLDB will support
in the medium term --- the only place we know of where it's a
problem is instance methods in Windows, where variadic functions
are implicitly cdecl.  We may have a more abstracted base on which
to build a solution by then.

Michael Gottesman 79b0967548 Revert "Revert "[APFloat] Removed APFloat constructor which initialized to either zero/NaN but allowed you to arbitrarily set the category of the float.""
This reverts commit r185099.

Looks like both the ppc-64 and mips bots are still failing after I reverted this
change.

Since:

1. The mips bot always performs a clean build,
2. The ppc64-bot failed again after a clean build (I asked the ppc-64
maintainers to clean the bot which they did... Thanks Will!),

I think it is safe to assume that this change was not the cause of the failures
that said builders were seeing. Thus I am recomitting.

Michael Gottesman a7b73d4534 Revert "Revert r184787: "Added arm_neon intrinsic tests.""
This reverts commit r184817. The failure Chandler was seeing was most likely the
bug that Bob Wilson fixed in r184870 (which was a bug caught by these tests).

To be safe, I just checked again on x86-64 mac os x/linux that this test passed
(which it did).

Tim Northover 0614fcd0e3 Prevent race in when stopping a "read thread"
Both StopReadThread and the thread being stopped set the thread id to
0 after m_read_thread_enabled was set to false. If the thread being
stopped got there first then StopReadThread called pthread_join on an
invalid thread number. This is not a Good Thing,

Should fix a fairly regular segfault when quitting on Linux.

Douglas Gregor f83b4ea8b6 Under -fms-extensions, only inject a friend tag name when we didn't see a tag with that name in an enclosing scope.
r177473 made us correctly consider only those declarations in the
enclosing namespace scope when looking for a friend declaration. Under
ms-extensions mode, where we do some level of friend injection, this
meant that we were introducing a new tag type into a different scope
than what Microsoft actually does. Address this by only doing the
friend injection when we didn't see any tag with that name in any
outer scope. Fixes <rdar://problem/14250378>.

Michael Gottesman ccaf3321f1 Revert "[APFloat] Removed APFloat constructor which initialized to either zero/NaN but allowed you to arbitrarily set the category of the float."
This reverts commit r185095. This is causing a FileCheck failure on
the 3dnow intrinsics on at least the mips/ppc bots but not on the x86
bots.

Reverting while I figure out what is going on.

Michael Gottesman 03255a1675 [APFloat] Removed APFloat constructor which initialized to either zero/NaN but allowed you to arbitrarily set the category of the float.
The category which an APFloat belongs to should be dependent on the
actual value that the APFloat has, not be arbitrarily passed in by the
user. This will prevent inconsistency bugs where the category and the
actual value in APFloat differ.

I also fixed up all of the references to this constructor (which were
only in LLVM).

Chad Rosier ccd0664393 Improve the compression of the tablegen DiffLists by introducing a new sort
algorithm when assigning EnumValues to the synthesized registers.

The current algorithm, LessRecord, uses the StringRef compare_numeric
function.  This function compares strings, while handling embedded numbers.
For example, the R600 backend registers are sorted as follows:

  T1
  T1_W
  T1_X
  T1_XYZW
  T1_Y
  T1_Z
  T2
  T2_W
  T2_X
  T2_XYZW
  T2_Y
  T2_Z

In this example, the 'scaling factor' is dEnum/dN = 6 because T0, T1, T2
have an EnumValue offset of 6 from one another.  However, in other parts
of the register bank, the scaling factors are different:

dEnum/dN = 5:
  KC0_128_W
  KC0_128_X
  KC0_128_XYZW
  KC0_128_Y
  KC0_128_Z
  KC0_129_W
  KC0_129_X
  KC0_129_XYZW
  KC0_129_Y
  KC0_129_Z

The diff lists do not work correctly because different kinds of registers have
different 'scaling factors'.  This new algorithm, LessRecordRegister, tries to
enforce a scaling factor of 1.  For example, the registers are now sorted as
follows:

  T1
  T2
  T3
  ...
  T0_W
  T1_W
  T2_W
  ...
  T0_X
  T1_X
  T2_X
  ...
  KC0_128_W
  KC0_129_W
  KC0_130_W
  ...

For the Mips and R600 I see a 19% and 6% reduction in size, respectively.  I
did see a few small regressions, but the differences were on the order of a
few bytes (e.g., AArch64 was 16 bytes).  I suspect there will be even
greater wins for targets with larger register files.

Patch reviewed by Jakob.

Tom Stellard 1baa03aba6 R600: Remove alu-split.ll test
The purpose of this test was to check boundary conditions for the size
of an ALU clause.  This test is very sensitive to changes to the
optimizer or scheduler, because it requires an exact number of ALU
instructions in order to remain valid.  It's not good to have a test
this sensitive, because it is confusing to developers who implement
optimizations and then 'break' the test.

I'm not sure if there is a good way to test these limits using lit, but
if I can come up with replacement test that isn't as sensitive I'll add
it back to the tree.
