Enable LoopLoadElimination by default
Summary:
I re-benchmarked this and results are similar to original results in
D13259:
On ARM64:
SingleSource/Benchmarks/Polybench/linear-algebra/solvers/dynprog -59.27%
SingleSource/Benchmarks/Polybench/stencils/adi -19.78%
On x86:
SingleSource/Benchmarks/Polybench/linear-algebra/solvers/dynprog -27.14%
And of course the original ~20% gain on SPECint_2006/456.hmmer with Loop
Distribution.
In terms of compile time, there is ~5% increase on both
SingleSource/Benchmarks/Misc/oourafft and
SingleSource/Benchmarks/Linkpack/linkpack-pc. These are both very tiny
loop-intensive programs where SCEV computations dominates compile time.
The reason that time spent in SCEV increases has to do with the design
of the old pass manager. If a transform pass does not preserve an
analysis we *invalidate* the analysis even if there was *no*
modification made by the transform pass.
This means that currently we don't take advantage of LLE and LV sharing
the same analysis (LAA) and unfortunately we recompute LAA *and* SCEV
for LLE.
(There should be a way to work around this limitation in the case of
SCEV and LAA since both compute things on demand and internally cache
their result. Thus we could pretend that transform passes preserve
these analyses and manually invalidate them upon actual modification.
On the other hand the new pass manager is supposed to solve so I am not
sure if this is worthwhile.)

[WinEH] Make setjmp work correctly with EH
32-bit X86 EH on Windows utilizes a stack of registration nodes
allocated and deallocated on entry/exit. A registration node contains a
bunch of EH personality specific information like which try-state we are
currently in.
Because a setjmp target allows control flow from arbitrary program
points, there is no way to ensure that the try-state we are in is
correctly updated once we transfer control.
MSVC compatible compilers, like MSVC and ICC, utilize runtime helpers to
reinitialize the try-state when a longjmp occurs. This is implemented
by adding additional arguments to _setjmp3: the desired try-state and
a helper routine to update the try-state.

These are really just stubs for now, but they give a nice API surface
that Clang or other tools can start learning about and enabling for
experimentation.
I've also wired up parsing various synthetic module pass names to
generate these set pipelines. This allows the pipelines to be combined
with other passes and have their order controlled, with clear separation
between the *kind* of canned pipeline, and the *level* of optimization
to be used within that canned pipeline.
The most interesting part of this patch is almost certainly the spec for
the different optimization levels. I don't think we can ever have hard
and fast rules that would make it easy to determine whether a particular
optimization makes sense at a particular level -- it will always be in
large part a judgement call. But hopefully this will outline the
expected rationale that should be used, and the direction that the
pipelines should be taken. Much of this was based on a long llvm-dev

these pipelines, and now, at long long last I'm returning to the task of

IIUC, range was an experiment to see how N3350 would work in LLD.
It turned out it didn't get traction, and it is basically duplicate

AMDGPU: More bits of frame index are known to be zero
The maximum private allocation for the whole GPU is 4G,
so the maximum possible index for a single workitem is the
maximum size divided by the smallest granularity for a dispatch.
This increases the number of known zero high bits, which
enables more offset folding. The maximum private size per
workitem with this is 128M but may be smaller still.

DAGCombiner: Don't unnecessarily swap operands in ReassociateOps
In the case where op = add, y = base_ptr, and x = offset, this
transform:
(op y, (op x, c1)) -> (op (op x, y), c1)
breaks the canonical form of add by putting the base pointer in the
second operand and the offset in the first.
This fix is important for the R600 target, because for some address
spaces the base pointer and the offset are stored in separate register
classes. The old pattern caused the ISel code for matching addressing
modes to put the base pointer and offset in the wrong register classes,
which required no-trivial code transformations to fix.

[UBSan] Fix isDerivedFromAtOffset on iOS ARM64
Summary:
iOS on ARM64 doesn't unique RTTI.
Ref: clang's iOS64CXXABI::shouldRTTIBeUnique()
Due to this, pointer-equality will not necessarily work in this
architecture, across dylib boundaries.
dynamic_cast<>() will (as expected) still work, since Apple ships with
one prepared for this, but we can't rely on the type names being
pointer-equal.
I've limited the expensive strcmp check to the specific architecture
which needs it.
Example which triggers this bug:
lib.h:
struct X {
virtual ~X() {}
};
X *libCall();
lib.mm:
X *libCall() {
return new X;
}
prog.mm:
int main() {
X *px = libCall();
delete px;
}
Expected output: Nothing
Actual output:
<unknown>: runtime error: member call on address 0x00017001ef50 which does not point to an object of type 'X'
0x00017001ef50: note: object is of type 'X'
