Peter Collingbourne a1099840ff [dfsan] Abort at runtime on indirect calls to uninstrumented vararg functions.
We currently have no infrastructure to support these correctly.

This is accomplished by generating a call to a runtime library function that
aborts at runtime in place of the regular wrapper for such functions. Direct
calls are rewritten in the usual way during traversal of the caller's IR.

We also remove the "split-stack" attribute from such wrappers, as the code
generator cannot currently handle split-stack vararg functions.

Ben Langmuir 6caebfda78 Remove superceded warning warn_forgotten_module_header
This DefaultIgnore warning under -Wincomplete-module was firing on
any module map files that happened to be parsed (it's only supposed to
fire on headers), and it has been superceded by
-Wnon-modular-include-in-module anyway.

For compatibility, I rewired -Wincomplete-module to imply
-Wnon-modular-include-in-module.

Andrea Di Biagio ce46b97b48 [X86] Teach method 'isVectorClearMaskLegal' how to check for legal blend masks.
This patch improves the folding of vector AND nodes into blend operations for
targets that feature SSE4.1. A vector AND node where one of the operands is
a constant build_vector with elements that are either zero or all-ones can be
converted into a blend.

This allows for example to simplify the following code:

define <4 x i32> @test(<4 x i32> %A, <4 x i32> %B) {
  %1 = and <4 x i32> %A, <i32 0, i32 0, i32 0, i32 -1>
  %2 = and <4 x i32> %B, <i32 -1, i32 -1, i32 -1, i32 0>
  %3 = or <4 x i32> %1, %2
  ret <4 x i32> %3
}

Before this patch llc (-mcpu=corei7) generated:
        andps  LCPI1_0(%rip), %xmm0, %xmm0
        andps  LCPI1_1(%rip), %xmm1, %xmm1
        orps   %xmm1, %xmm0, %xmm0
        retq

With this patch we generate a single 'vpblendw'.

Oliver Stannard 9e89d8cc5c [ARM] Honor FeatureD16 in the assembler and disassembler
Some ARM FPUs only have 16 double-precision registers, rather than the
normal 32. LLVM represents this with the D16 target feature. This is
currently used by CodeGen to avoid using high registers when they are
not available, but the assembler and disassembler do not.

I fix this in the assmebler and disassembler rather than the
InstrInfo.td files, as the latter would require a large number of
changes everywhere one of the floating-point instructions is referenced
in the backend. This solution is similar to the one used for
co-processor numbers and MSR masks.

Jay Foad 70a3841a8f Get the Linux ptrace test working on PowerPC64
The test refers to user_regs_struct.rip so it can only ever have worked
on x86-64. Put this code inside an appropriate #if, and add a similar
case for PowerPC64. (If we do likewise for ARM we can probably remove
the XFAILs, but I have no way of testing that.)

Those changes are enough to get the test working for me on big-endian
PowerPC64 Fedora 19.

David Majnemer ff9848ab08 PECOFF: Set the AddressOfRelocationTable in the DOS header

Tim Northover dc0d9e46a5 ARM: try to add extra CS-register whenever stack alignment >= 8.
We currently try to push an even number of registers to preserve 8-byte
alignment during a function's prologue, but only when the stack alignment is
prcisely 8. Many of the reasons for doing it apply also when that alignment > 8
(the extra store is often free, and can save another stack adjustment, though
less frequently for 16-byte stack alignment).
