MaheshRavishankar ba72cfe734 [mlir] Add an interface to allow operations to specify how they can be tiled.
An interface to allow for tiling of operations is introduced. The
tiling of the linalg.pad_tensor operation is modified to use this
interface.

Chris Lattner faf1c22408 [Builder] Eliminate the StringRef/StringAttr forms of getSymbolRefAttr.
The StringAttr version doesn't need a context, so we can just use the
existing `SymbolRefAttr::get` form.  The StringRef version isn't preferred
so we want to encourage people to use StringAttr.

There is an additional form of getSymbolRefAttr that takes a (SymbolTrait
implementing) operation.  This should also be moved, but I'll do that as
a separate patch.

Keno Fischer ea8539111d [COFF] Force Symbols containing '.' to be quoted
In D87099, the mangler learned to quote export directives that contain
special characters. Only alhpanumerical characters as well as
'_', '$', '.' and '@' were exmpt from this quoting. However, at least
binutils considers an unquoted '.' to be syntax and object files
containing such symbols will cause errors during linking. Fix that
by removing '.' from the list of allowed exemptions.

Andrew Litteken c58d4c4bd3 [IROutliner] Changing outliner to prioritize reductions on assembly rather than IR instruction
Currently, the IROutliner uses a simple metric to outline the largest amount
of IR possible to outline first if it fits the cost model. This is model
loses out on smaller blocks of code that have higher reductions in cost that
are contained within larger blocks of IR.

This reverses the order, where we calculate all of the costs first, and then
reorder and extract items based on the calculated results.

Craig Topper 201f6446da [LegalizeTypes][X86] Improve ExpandIntRes_FP_TO_SINT/ExpandIntRes_FP_TO_UINT when input is SoftPromoteHalf.
Instead of splitting off the fp16 to float conversion and generating
a libcall, we should split the operation into fp16 to float and float
to integer operations. This will allow the float to integer conversion
to go through any custom handling the target has. If the target doesn't
have custom handling then we should come back to ExpandIntRes_FP_TO_SINT/
ExpandIntRes_FP_TO_UINT automatically to create the libcall.

This avoids generating libcalls on 32-bit X86. These library functions may
not exist in 32-bit libgcc. At least for LLVM, we never generate them when
hardware floating point instructions are available.

Bjorn Pettersson 789f01283d [SelectionDAG] Fix miscompile bugs related to smul.fix.sat with scale zero
When expanding a SMULFIXSAT ISD node (usually originating from
a smul.fix.sat intrinsic) we've applied some optimizations for
the special case when the scale is zero. The idea has been that
it would be cheaper to use an SMULO instruction (if legal) to
perform the multiplication and at the same time detect any overflow.
And in case of overflow we could use some SELECT:s to replace the
result with the saturated min/max value. The only tricky part
is to know if we overflowed on the min or max value, i.e. if the
product is positive or negative. Unfortunately the implementation
has been incorrect as it has looked at the product returned by the
SMULO to determine the sign of the product. In case of overflow that
product is truncated and won't give us the correct sign bit.

This patch is adding an extra XOR of the multiplication operands,
which is used to determine the sign of the non truncated product.

This patch fixes PR51677.

David Green efa340fbd2 [ARM] Workaround tailpredication min/max costmodel
The min/max intrinsics are not yet canonical, but when they are the tail
predications analysis will change from treating them like icmp to
treating them like intrinsics. Unfortunately, they can currently produce
better code by not being tail predicated thanks to the vectorizer picking
higher VF's and the backend folding to better instructions (especially
for saturate patterns). In the long run we will need to improve the
vectorizers cost modelling, recognizing the instruction directly, but in
the meantime this treats min/max as before to prevent performance
regressions.

Nico Weber 83df94067d [lld/mac] Tweak estimateStubsInRangeVA a bit
- Move a few variables closer to their uses, remove some completely
  (no behavior change)
- Add some comments
- Make maxPotentialThunks include calls to stubs. It's possible that
  an earlier call to a stub late in the stub table will need a thunk,
  and that inserted thunk could push a stub earlier in the stub table
  out of range. This is unlikely to happen, but usually there are
  way fewer stub calls than non-stub calls, so if we're doing a
  conservative approximation here we might as well do it correctly.
  (For chromium's unit_tests target, 134421/242639 stub calls are
  direct calls without this change, compared to 134408/242639 with
  this change)

No real, meaningful behavior difference.

decide we can use a rotate, but then fail the legality checks. If
that happens we should not fall back to a vector type. This triggers

In theory we could use a shufflevector in place of the rotate, but

such as "./" that is relative path string , it will crash as soon as I press the
[Tab] key. For example, debugging an executable file named "hello" that is
compiled from a file named "hello.c" , and I’ll put a breakpoint on line 3 of
hello.c.

```

The crash was caused because substr() (in lldb/source/Host/common/Editline.cpp)

I modified the code that erase the user's intput string from current line and
then add the completion string.

Djordje Todorovic 86f5288eae [LiveDebugValues] Cleanup Transfers when removing Entry Value
If we encounter a new debug value, describing the same parameter,
we should stop tracking the parameter's Entry Value. At that point,
in some cases, the Transfer which uses the parameter's Entry Value,
is already emitted. Thanks to the RemoveRedundantDebugValues pass,
many problems with incorrect instruction order and number of DBG_VALUEs
are fixed. However, we still cannot rely on the rule that each new
debug value is set by the previous non-debug instruction in Machine
Basic Block.

When new parameter debug value triggers removal of Backup Entry Value
for the same parameter, do the cleanup of Transfers emitted from Backup
Entry Values. Get the Transfer Instruction which created the new debug
value and search for debug values already emitted from the to-be-deleted
Backup Entry Value and attached to the Transfer Instruction. If found,
delete the Transfer and remove "primary" Entry Value Var Loc from
OpenRanges.
