Andrzej Warzynski fa9439fac8 [AArch64][SVE] Add intrinsics for first-faulting gather loads
Summary:
The following intrinsics are added:
  * @llvm.aarch64.sve.ldff1.gather
  * @llvm.aarch64.sve.ldff1.gather.index
  * @llvm.aarch64.sve.ldff1.gather_sxtw
  * @llvm.aarch64.sve.ldff1.gather.uxtw
  * @llvm.aarch64.sve.ldff1.gather_sxtw.index
  * @llvm.aarch64.sve.ldff1.gather.uxtw.index
  * @llvm.aarch64.sve.ldff1.gather.scalar.offset

Although this patch is quite substantial, the vast majority of the
implementation is just a 'copy & paste' of the implementation of regular
gather loads, including tests. There's only a handful of new
definitions:
  * AArch64ISD nodes defined in AArch64ISelLowering.h (e.g. GLDFF1)
  * Seleciton DAG Types in AArch64SVEInstrInfo.td (e.g.
    AArch64ldff1_gather)
  * intrinsics in IntrinsicsAArch64.td (e.g. aarch64_sve_ldff1_gather)
  * Pseudo instructions in SVEInstrFormats.td to workaround the issue of
    use-before-def for the FFR register.

Hans Wennborg 5122e82870 [driver][darwin] Don't use -platform_version flag by default (PR44813)
The code in llvmorg-10-init-12188-g25ce33a6e4f is a breaking change for
users of older linkers who don't pass a version parameter, which
prevents a drop-in clang upgrade. Old tools can't know about what future
tools will do, so as a general principle the burden should be new tools
to be compatible by default. Also, for comparison, none of the other
tests of Version within AddLinkArgs add any new behaviors unless the
version is explicitly specified. Therefore, this patch changes the
-platform_version behavior from opt-out to opt-in.

David Stenberg 6d857166d2 [DebugInfo] Describe call site values for chains of expression producing instrs
Summary:
If the describeLoadedValue() hook produced a DIExpression when
describing a instruction, and it was not possible to emit a call site
entry directly (the value operand was not an immediate nor a preserved
register), then that described value could not be inserted into the
worklist, and would instead be dropped, meaning that the parameter's
call site value couldn't be described.

This patch extends the worklist so that each entry has an DIExpression
that is built up when iterating through the instructions.

This allows us to describe instruction chains like this:

  $reg0 = mv $fp
  $reg0 = add $reg0, offset
  call @call_with_offseted_fp

Since DW_OP_LLVM_entry_value operations can't be combined with any other
expression, such call site entries will not be emitted. I have added a
test, dbgcall-site-expr-entry-value.mir, which verifies that we don't
assert or emit broken DWARF in such cases.

the two lambda functions addToWorklist() and finishCallSiteParams() grow
a bit, so move those out to separate functions. This patch also prepares
for each parameter register having their own expression moving the
creation of the DbgValueLoc into finishCallSiteParams().

Nemanja Ivanovic c46b85aaf4 [LoopVectorize] Fix cost for calls to functions that have vector versions
A recent commit
(https://reviews.llvm.org/rG66c120f02560ef528a60924104ead66f330190f1) changed
the cost for calls to functions that have a vector version for some
vectorization factor. However, no check is performed for whether the
vectorization factor matches the current one being cost modeled. This leads to
attempts to widen call instructions to a vectorization factor for which such a
function does not exist, which in turn leads to an assertion failure.

This patch adds the check for vectorization factor (i.e. not just that the
called function has a vector version for some VF, but that it has a vector
version for this VF).

Craig Topper 15e2831fcd [X86] Explicitly pass Pointer, MachinePointerInfo and Alignment to BuildFILD.
Previously this code was called into two ways, either a FrameIndexSDNode
was passed in StackSlot. Or a load node was passed in the argument
called StackSlot. This was determined by a dyn_cast to FrameIndexSDNode.

In the case of a load, we had to go find the real pointer from
operand 0 and cast the node to MemSDNode to find the pointer info.

For the stack slot case, the code assumed that the stack slot
was perfectly aligned despite not being the creator of the slot.

This commit modifies the interface to make the caller responsible
for passing all of the required information to avoid all the
guess work and reverse engineering.

I'm not aware of any issues with the original code after an
earlier commit to fix the alignment of one of the stack objects.
This is just clean up to make the code less surprising.
