[mlir] [mem2reg] Adapt to be pattern-friendly.

This revision modifies the mem2reg interfaces and algorithm to be more
omfortable to use as a pattern. The motivation behind this is that
currently the pattern needs to be applied to the scope op of the region
in which allocators should be promoted. However, a more natural way to
apply the pattern would be to apply it on the allocator directly. This
is not only clearer but easier to parallelize.

This revision changes the mem2reg pattern to operate this way. This
required restraining the interfaces to only mutate IR using
RewriterBase, as the previously used escape hatch is not granular enough
to match on the region that is modified only. This has the unfortunate
cost of preventing batching allocator promotion and making the block
argument adding logic more complex. Because batching no longer made any
sense, I made the internal analyzer/promoter decoupling private again.

This also adds statistics to the mem2reg infrastructure.

FastRegAlloc: Fix implicit operands not rewritten

This patch fixes a potential crash due to RegAllocFast not rewriting virtual
registers. This essentially happens because of a call to
MachineInstr::addRegisterKilled() in the process of allocating a "killed" vreg.
The former can eventually delete implicit operands without RegAllocFast
noticing, leading to some operands being "skipped" and not rewritten to use
physical registers.

Note that I noticed this crash when working on a solution for tying a register
with one/multiple of its sub-registers within an instruction. (See problem
description here:
https://discourse.llvm.org/t/pass-to-tie-an-output-operand-to-a-subregister-of-an-input-operand/67184).

Aside from this fix, I believe there could be further improvements to the
RegAllocFast when it comes to instructions with multiple uses of a same virtual
register. You can see it in the added test where the implicit uses have been
re-written in a somewhat surprising way because of phase ordering. Ultimately,
when allocating vregs for an instruction, I believe we should iterate on the
vregs it uses (and then process all the operands that use this vregs), instead
of directly iterating on operands and somewhat assuming each operand uses a
different vreg. This would in the end be quite close to what
greedy+virtregrewriter does. If that makes sense, I would probably spin off
another patch (after I get more familiar with RegAllocFast).

use the usual code clamped to BitWidth-1 rather than just giving up
entirely.

Additionally, there was an implementation bug where the known zero
bits for the individual shift amounts were not set in the shl/lshr

[OpenMP] Use CMAKE_CXX_STANDARD for setting the C++ version

Previously, we tried to check whether the -std=c++17 option was
supported and manually add the flag. That doesn't work for compilers
that do support C++17 but use a different option syntax, like
clang-cl.

OpenMP itself probably doesn't specifically require C++17, therefore
CXX_STANDARD_REQUIRED is left off, but in some cases, we may
have code that only works in C++17 mode.

refactoring that works when built with Clang in C++17 mode, but not
in C++14 mode. MSVC accepts the construct in both language modes.

For libomptarget, we've had specific checks that require C++17
(or the -std=c++17 option) to be supported. It's doubtful that
libomptarget has got any code which more specifically requires C++17;
this seems to be a remnant from when libomptarget was added
originally in 2467df6e4f04e3d0e8e78d662473ba1b87c0a885 / D14031.
At that point, the rest of OpenMP didn't require C++11, while
libomptarget did require it. Now, it's unlikely that anyone attempts
building it with a toolchain that doesn't support C++11.

At this point, we could also probably just set CXX_STANDARD_REQUIRED
to true, requiring C++17 as baseline for all the OpenMP libraries.

[LLVM][Uniformity] Improve detection of uniform registers

The MachineUA now queries the target to determine if a given register holds a
uniform value. This is determined using the corresponding register bank if
available, or by a combination of the register class and value type. This
assumes that the target is optimizing for performance by choosing registers, and
the target is responsible for any mismatch with the inferred uniformity.

For example, on AMDGPU, an SGPR is now treated as uniform, except if the
register bank is VCC (i.e., the register holds a wave-wide vector of 1-bit
values) or equivalently if it has a value type of s1.

 - This does not always work with inline asm, where the register bank or the
   value type might not be present. We assume that the SGPR is uniform, because
   it is not expected to be s1 in the vast majority of cases.
 - The pseudo branch instruction SI_LOOP is now hard-coded to be always
   divergent, although its condition is an SGPR.

long the function name is, like this:

```

People are unlikely to use this feature in a Verilog port list because
the formatter already puts the port list on its own lines.  A comment
at the start of a port list is probably a comment for the port on the

[RISCV][MC] .debug_line/.debug_frame/.eh_frame: emit relocations for assembly input files with relaxation

When assembling `.debug_line` for both explicitly specified and synthesized
`.loc` directives. the integrated assembler may incorrectly omit relocations for
-mrelax.

For an assembly file, we have a `MCAssembler` object and `evaluateAsAbsolute`
will incorrectly fold `AddrDelta` to a constant (which is not true in the
presence of linker relaxation).
`MCDwarfLineAddr::Emit` will emit a special opcode, which does not take into
account of linker relaxation. This is a sufficiently complex function that
I think should be called in any "fast paths" for linker relaxation aware assembling.

The following script demonstrates the bugs.

```
cat > x.c <<eof
void f();
void _start() {
  f();
  f();
  f();
}
eof
# C to object file: correct DW_LNS_fixed_advance_pc

# Assembly to object file with synthesized line number information: incorrect special opcodes
clang --target=riscv64 -S x.c && clang --target=riscv64 -g -c x.s

llvm-dwarfdump --debug-line -v x.o | grep \ DW_LNS_fixed_advance_pc -q; test $? -eq 1
```

The `MCDwarfLineAddr::Emit` code path is an old optimization in commit
57ab708bdd3231b23a8ef4978b11ff07616034a2 (2010) that seems no longer relevant.
It don't trigger for direct machine code emission (label differences are not
foldable without a `MCAssembler`). MCDwarfLineAddr::Emit does complex operations
that are repeated in MCAssembler::relaxDwarfLineAddr, which an intricate RISCV
override.

Let's remove the "fast path". Assembling the assembly output of
X86ISelLowering.cpp with `-g` may be 2% slower, but I think the cost is fine.
There are opportunities to make the "slow path" faster, e.g.

* Optimizing the current new MC*Fragment pattern that allocates new fragments on
  the heap.
* Reducing the number of relaxation times for .debug_line and .debug_frame, as
  well as possibly other sections using LEB128. For instance, LEB128 can have a
  one-byte estimate to avoid the second relaxation iteration.

For assembly input with -mno-relax, in theory we can prefer special opcodes to
DW_LNS_fixed_advance_pc to decrease the size of .debug_line, but such a change
may be overkill and unnecessarily diverge from -mrelax behaviors and GCC.

---

For .debug_frame/.eh_frame, MCDwarf currently emits DW_CFA_advance_loc without
relocations. Remove the special case to enable relocations. Similar to
.debug_line, even without the bug fix, the MCDwarfFrameEmitter::encodeAdvanceLoc
special case is a sufficiently complex code path that should be avoided.

---

When there are more than one section, we generate .debug_rnglists for
DWARF v5. We currently emit DW_RLE_start_length using ULEB128, which
is incorrect. The new test gen-dwarf.s adds a TODO.

---

About other `evaluateAsAbsolute` uses. `MCObjectStreamer::emit[SU]LEB128Value`
have similar code to MCDwarfLineAddr. They are fine to keep as we don't have
LEB128 relocations to correctly represent link-time non-constants anyway.

---

In the future, we should investigate ending a MCFragment for a relaxable
instruction, to further clean up the assembler support for linker relaxation
and fix `evaluateAsAbsolute`.

See bbea64250f65480d787e1c5ff45c4de3ec2dcda8 for some of the related code.

[CMake] Use LLVM own tools in extract_symbols.py

As for now, 'extract_symbols.py' can use several tools to extract
symbols from object files and libraries and to guess if the target is
32-bit Windows. The tools are being found via PATH, so in most cases,
they are just system tools. This approach has a number of limitations,
in particular:

* System tools may not be able to handle the target format in case of
  cross-platform builds,
* They cannot read symbols from LLVM bitcode files, so the staged LTO

* The auto-selected tools may be suboptimal (see D113557),
* Support for multiple tools for a single task increases the complexity
  of the script code.

The patch proposes using LLVM's own tools to solve these issues.
Specifically, 'llvm-readobj' detects the target platform, and 'llvm-nm'
reads symbols from all supported formats, including bitcode files. The
tools can be built in Release mode for the host platform or overridden
using CMake settings 'LLVM_READOBJ' and 'LLVM_NM' respectively. The

Dave Lee [Mon, 8 May 2023 17:13:33 +0000 (10:13 -0700)]
[lldb] Refine call to decl printing helper (NFC)

When `ValueObjectPrinter` calls its `m_decl_printing_helper`, not all state is passed to
the helper. In particular, the helper doesn't have access to `m_curr_depth`, and thus
can't act on the logic within `ShouldShowName`.

To address this, this change passes in a modified copy of `m_options`. The modified copy
has has `m_hide_name` set according to the results of `ShouldShowName`. This allows
helper functions to know whether the name should be shown or hidden, without having
access to `ValueObjectPrinter`'s full state.

This is NFC in mainline lldb, as the only decl printing helper doesn't make use of this.
However in swift-lldb at least, there are decl printing helpers that do need this
information passed to them. See https://github.com/apple/llvm-project/pull/6795 where a
test is also included.

[TOSA] Add QuantizationDialect to TOSA's dependentDialects

This adds QuantizationDialect to the dependent dialects of TOSA

LLVM ERROR: can't create type 'mlir::quant::UniformQuantizedType' because storage uniquer isn't initialized: the dialect was likely not loaded, or the type wasn't added with addTypes<...>() in the Dialect::initialize() method.
