c15b588852 [lld/mac] Don't assert during thunk insertion if there are undefined symbols
We end up calling resolveBranchVA(), which asserts for Undefineds.

As fix, just return early in Writer::run() if there are any diagnostics
after processing relocations (which is where undefined symbol errors are
emitted). This matches what the ELF port does.

75620fadf5 [RISCV] Change how we encode AVL operands in vector pseudoinstructions to use GPRNoX0.
This patch changes the register class to avoid accidentally setting
the AVL operand to X0 through MachineIR optimizations.

There are cases where we really want to use X0, but we can't get that
past the MachineVerifier with the register class as GPRNoX0. So I've
use a 64-bit -1 as a sentinel for X0. All other immediate values should
be uimm5. I convert it to X0 at the earliest possible point in the VSETVLI
insertion pass to avoid touching the rest of the algorithm. In
SelectionDAG lowering I'm using a -1 TargetConstant to hide it from
instruction selection and treat it differently than if the user
used -1. A user -1 should be selected to a register since it doesn't
fit in uimm5.

This is the rest of the changes started in D109110. As mentioned there,
I don't have a failing test from MachineIR optimizations anymore.

b6d1a31c1b [mlir][sparse] refine heuristic for iteration graph topsort
The sparse index order must always be satisfied, but this
may give a choice in topsorts for several cases. We broke
ties in favor of any dense index order, since this gives
good locality. However, breaking ties in favor of pushing
unrelated indices into sparse iteration spaces gives better
asymptotic complexity. This revision improves the heuristic.

Note that in the long run, we are really interested in using
ML for ML to find the best loop ordering as a replacement for
such heuristics.

29c3ef5a0e Remove blank from NaN string representation
Flang front end function DumpHexadecimal generates a string
representation of a REAL value.  When the value is a NaN, the string
contains a blank, as in "NaN 0x7fc00000".  This function is used by
lowering to generate a string that is then passed to llvm Support
function convertFromStringSpecials, which does not expect a blank
in the string.  Remove the blank to allow correct recognition of a
NaN by this llvm function.

Note that function DumpHexadecimal is not exercised by the front end
itself.  This functionality is only exercised by code that is not yet
present in llvm.

a375bfb5b7 [analyzer][NFCI] Allow clients of NoStateChangeFuncVisitor to check entire function calls, rather than each ExplodedNode in it
D105553 added NoStateChangeFuncVisitor, an abstract class to aid in creating
notes such as "Returning without writing to 'x'", or "Returning without changing
the ownership status of allocated memory". Its clients need to define, among
other things, what a change of state is.

For code like this:

f() {
  g();
}

foo() {
  f();
  h();
}

We'd have a path in the ExplodedGraph that looks like this:

             -- <g> -->
            /          \
         ---     <f>    -------->        --- <h> --->
        /                        \      /            \
--------        <foo>             ------    <foo>     -->

When we're interested in whether f neglected to change some property,
NoStateChangeFuncVisitor asks these questions:

                       ÷×~
                -- <g> -->
           ß   /          \$    @&#*
            ---     <f>    -------->        --- <h> --->
           /                        \      /            \
   --------        <foo>             ------    <foo>     -->

Has anything changed in between # and *?
Has anything changed in between & and *?
Has anything changed in between @ and *?
...
Has anything changed in between $ and *?
Has anything changed in between × and ~?
Has anything changed in between ÷ and ~?
...
Has anything changed in between ß and *?
...
This is a rather thorough line of questioning, which is why in D105819, I was
only interested in whether state *right before* and *right after* a function
call changed, and early returned to the CallEnter location:

if (!CurrN->getLocationAs<CallEnter>())
  return;
Except that I made a typo, and forgot to negate the condition. So, in this
patch, I'm fixing that, and under the same hood allow all clients to decide to
do this whole-function check instead of the thorough one.

dc5dd77ac7 [AArch64][SME] Support NEON vector to GPR integer moves in streaming mode
A small subset of the NEON instruction set is legal in streaming mode.
This patch adds support for the following vector to integer move
instructions:

  0x00 1110 0000 0001 0010 11xx xxxx xxxx # SMOV W|Xd,Vn.B[0]
  0x00 1110 0000 0010 0010 11xx xxxx xxxx # SMOV W|Xd,Vn.H[0]
  0100 1110 0000 0100 0010 11xx xxxx xxxx # SMOV Xd,Vn.S[0]
  0000 1110 0000 0001 0011 11xx xxxx xxxx # UMOV Wd,Vn.B[0]
  0000 1110 0000 0010 0011 11xx xxxx xxxx # UMOV Wd,Vn.H[0]
  0000 1110 0000 0100 0011 11xx xxxx xxxx # UMOV Wd,Vn.S[0]
  0100 1110 0000 1000 0011 11xx xxxx xxxx # UMOV Xd,Vn.D[0]

Only the zero index variants are legal, all others indexes are illegal.
To support this, new instructions are defined specifically for zero
index which is hardcoded, along an implicit 'VectorIndex0' operand.
Since the index operand is implicit and takes no bits in the encoding,
custom decoding is required to add the operand.

I'm not sure if this is the best approach but the predicate constraint
on a subset of an operand is unusual. Would be interested to hear some
alternatives.

The instructions are predicated on 'HasNEONorStreamingSVE', i.e. they're
enabled by either +neon or +streaming-sve. This follows on from the work
in D106272 to support the subset of SVE(2) instructions that are legal
in streaming mode.

Depends on D107902.

49af2a6275 [mlir][flang] Do not prevent integer types from being parsed as MLIR keywords
DialectAsmParser::parseKeyword is rejecting `'i' digit+` while it is
a valid identifier according to mlir/docs/LangRef.md.

Integer types actually used to be TOK_KEYWORD a while back before the
change: 6af866c58d.

This patch Modifies `isCurrentTokenAKeyword` to return true for tokens that
match integer types too.

The motivation for this change is the parsing of `!fir.type<{` `component-name: component-type,`+ `}>`
type in FIR that represent Fortran derived types. The component-names are
parsed as keywords, and can very well be i32 or any ixxx (which are
valid Fortran derived type component names).

The Quant dialect type parser had to be modified since it relied on `iw` not
being parsed as keywords.

The size of common block should be extended to cover any storage
sequence that are storage associated with the common block via

In symbol size and offset computation, the size of the common block
was not always extended to cover storage association. It was only done
if the "base symbol of an equivalence group"(*) appeared in a common block
statement. Correct this to cover all cases where a symbol appearing in a
common block statement is storage associated.

(*) the base symbol of an equivalence group is the symbol whose storage
starts first in a storage association (if several symbols starts first,
the base symbol is the last one visited by the algorithm going through
the equivalence sets).
