Sanjoy Das 7869d4b846 [LazyCallGraph] Port test case from r240039 to LCG.
Summary:
r240039 adds a test case to check that CallGraph does the right thing
with respect to non-leaf intrinsics like statepoint and patchpoint.
This ports the same test case to LazyCallGraph.  LazyCallGraph already
does the right thing with respect to escaping function pointers so there
is no need to change any code.

Peter Collingbourne 581f438f4c Driver: add support for linking the UBSan runtime library on Windows.
On Windows the user may invoke the linker directly, so we might not have an
opportunity to add runtime library flags to the linker command line. Instead,
instruct the code generator to embed linker directive in the object file
that cause the required runtime libraries to be linked.

We might also want to do something similar for ASan, but it seems to have
its own special complexities which may make this infeasible.

Eric Christopher e100226879 Implement TargetTransformInfo::hasCompatibleFunctionAttributes for X86.
This checks subtarget feature compatibility for inlining by verifying
that the callee is a strict subset of the caller's features. This includes
the cpu as part of the subtarget we can get via the incoming functions as
the backend takes CPUs as feature sets.

This allows us to inline things like:

int foo() { return baz(); }

int __attribute__((target("sse4.2"))) bar() {
  return foo();
}

so that generic code can be inlined into specialized functions.

Rui Ueyama 18f8d2c5c0 COFF: Change GCRoot member type from StringRef to Undefined. NFC.

This patch adds initial general-dynamic TLS support for AArch64.  Currently
no optimization is done to realx for more performance-wise models (initial-exec

Jingyue Wu a0a56601c0 [NVPTX] expand extload/truncstore for vectors of floats
Summary:
According to PTX ISA:

For convenience, ld, st, and cvt instructions permit source and destination data operands to be wider than the instruction-type size, so that narrow values may be loaded, stored, and converted using regular-width registers. For example, 8-bit or 16-bit values may be held directly in 32-bit or 64-bit registers when being loaded, stored, or converted to other types and sizes. The operand type checking rules are relaxed for bit-size and integer (signed and unsigned) instruction types; floating-point instruction types still require that the operand type-size matches exactly, unless the operand is of bit-size type.

So, the ISA does not support load with extending/store with truncatation for floating numbers. This is reflected in setting the loadext/truncstore actions to expand in the code for floating numbers, but vectors of floating numbers are not taken care of.

As a result, loading a vector of floats followed by a fp_extend may be combined by DAGCombiner to a extload, and the extload may be lowered to NVPTXISD::LoadV2 with extending information. However, NVPTXISD::LoadV2 does not perform extending, and no extending instructions are inserted. Finally, PTX instructions with mismatched types are generated, like
ld.v2.f32 {%fd3, %fd4}, [%rd2]

This patch adds the correct actions for vectors of floats, so DAGCombiner would not create loads with extending, and correct code is generated.

Patched by Gang Hu. 

Test Plan: Test case attached.

Reid Kleckner eb11c41900 [SEH] Delete the 32-bit IR lowering for __finally blocks and use x64
32-bit finally funclets are intended to be called both directly from the
parent function and indirectly from the EH runtime. Because we aren't
contorting LLVM's X86 prologue to match MSVC's, calling the finally
block directly passes in a different value of EBP than the one that the
runtime provides. We need an adapter thunk to adjust EBP to the expected
value. However, WinEHPrepare already has to solve this problem when
cleanups are not pre-outlined, so we can go ahead and rely on it rather
than duplicating work.

Now we only do the llvm.x86.seh.recoverfp dance for 32-bit SEH filter
functions.

the frontend is pre-outlining the finally bodies so that it ends up
