Provided test case crashes otherwise.
Much like to the opposite case.

Provided test case crashes otherwise.

If NewTy is already DL.getIntPtrType(NewTy),
CreateBitCast() won't actually create any bitcast,
so we are better off just doing the general thing.

[IR] GetUnderlyingObject(), stripPointerCastsAndOffsets(): don't crash on `bitcast <1 x i8*> to i8*`

I'm not sure how to write standalone tests for each of two changes here.
If either one of these two fixes is missing, the test fill crash.

Even if we know that RHS of a bitcast is a pointer,
we can't assume LHS is, because it might be
a single-element vector of pointer.

This makes it usable from outside of SCEV,
while previously it was internal to the ScalarEvolution.cpp

In particular, i want to use it in an WIP alloca promotion helper pass,
to analyze if some SCEV is a multiple of some other SCEV.

This reverts commit 39819ccd.

The dependency was introduced in
5134020e. The only functional change
from this removal would be the new PM interface for the two codegen
passes. This is not necessary since we don't have codegen pipeline using
new PM yet. This removal is to break the potential circular dependency between
Passes and CodeGen once the codegen begins to gain new PM support.

This reverts commit b5740105.

The ARM ARM considers p10/p11 valid arguments for MCR/MRC instructions.
MRC instructions with p10 arguments are also used in kernel code which
is shared for different architectures. Turn usage of p10/p11 to warnings
for ARMv7/ARMv8-M.

llvm/include/llvm/TextAPI/MachO/ inappropriately uses the llvm::MachO namespace (this is for BinaryFormat and Object) and causes conflicts in some MSVC builds::

http://lab.llvm.org:8011/builders/sanitizer-windows/builds/65324/steps/stage%201%20build/logs/stdio

Removing `using namespace llvm::MachO` should decrease name collisions.

I'm probably going to rewrite this function anyway, but, in
the meanwhile.

Summary:
Get back `const` partially lost in one of recent changes.
Additionally specify explicit qualifiers in few places.

EmitTargetMetadata passed to emitTargetMD a null pointer as returned
from GetGlobalValue, for an unused inline function which has been
removed from the module at that point.

A FIXME in CodeGenModule.cpp commented that the calling code in
EmitTargetMetadata should be moved into the one target that needs it
(XCore). A review comment agreed. So the calling loop has been moved
into the XCore subclass. The check for null is done in that loop.

D68667 introduced a tighter limit to the number of GEPs to simplify
together. The limit was based on the vector element size of the pointer,
but the pointers themselves are not actually put in vectors.

IIUC we try to vectorize the index computations here, so we should base
the limit on the vector element size of the computation of the index.

This restores the test regression on AArch64 and also restores the
vectorization for a important pattern in SPEC2006/464.h264ref on
AArch64 (@test_i16_extend). We get a large benefit from doing a single
load up front and then processing the index computations in vectors.

Note that we could probably even further improve the AArch64 codegen, if
we would do zexts to i32 instead of i64 for the sub operands and then do
a single vector sext on the result of the subtractions. AArch64 provides
dedicated vector instructions to do so. Sketch of proof in Alive:

Otherwise, it's painful to insert new code.  There are many existing
examples in the same test file where the line numbers are not

I intend to do the same for several other OpenMP tests, but I want to
