each option.

The only place where this is not the case is the nullptr

HICPP guidelines alias this modernize check, and there is

If a chain of two selects share a true/false value and are controlled
by two setcc nodes, that are never both true, we can fold away one of

[mlir][sparse] Factoring out SparseTensorType class

This change adds a new `SparseTensorType` class for making the "dim" vs "lvl" distinction more overt, and for abstracting over the differences between sparse-tensors and dense-tensors.  In addition, this change also adds new type aliases `Dimension`, `Level`, and `FieldIndex` to make code more self-documenting.

Although the diff is very large, the majority of the changes are mechanical in nature (e.g., changing types to use the new aliases, updating variable names to match, etc).  Along the way I also made many variables `const` when they could be; the majority of which required only adding the keyword.  A few places had conditional definitions of these variables, requiring actual code changes; however, that was only done when the overall change was extremely local and easy to extract.  All these changes are included in the current patch only because it would be too onerous to split them off into a separate patch.

[InstCombine] fold icmp of the sum of ext bool based on limited range

For the pattern `(zext i1 X) + (sext i1 Y)`, the constant range is [-1, 1].
We can simplify the pattern by logical operations. Like:

```
    (zext i1 X) + (sext i1 Y) == -1 -->  ~X & Y
    (zext i1 X) + (sext i1 Y) == 0  --> ~(X ^ Y)
    (zext i1 X) + (sext i1 Y) == 1 --> X & ~Y
```
And other predicates can the combination of these results:

```
    (zext i1 X) + (sext i1 Y)) != -1 --> X | ~Y
    (zext i1 X) + (sext i1 Y)) s> -1 --> X | ~Y
    (zext i1 X) + (sext i1 Y)) u< -1 --> X | ~Y
    (zext i1 X) + (sext i1 Y)) s> 0 --> X & ~Y
    (zext i1 X) + (sext i1 Y)) s< 0 --> ~X & Y

Liren Peng [Wed, 15 Feb 2023 02:18:41 +0000 (02:18 +0000)]
[SeparateConstOffsetFromGEP] Fix: `b - a` matched `a - b` during reuniteExts

During the SeparateConstOffsetFromGEP pass, a - b and b - a will be
considered equivalent in some instances.

An example- the IR contains:

  BB1:
      %add = add %a, 511
      br label %BB2
  BB2:
      %sub2 = sub %b,  %a
      br label %BB3
  BB3:
      %sub1 = sub %add, %b
      %gep = getelementptr float, ptr %p, %sub1

Step 1 in the SeparateConstOffsetFromGEP pass, after split constant index:

  BB1:
      %add = add %a, 511
      br label %BB2
  BB2:
      %sub2 = sub %b,  %a
      br label %BB3
  BB3:
      %sub.t = sub %a, %b
      %gep.base = getelementptr float, ptr %p, %sub.t
      %gep = getelementptr float, ptr %gep.base, 511

Step 2, after reuniteExts:

  BB1:
      br label %BB2
  BB2:
      %sub2 = sub %b,  %a
      br label %BB3
  BB3:
      %gep.base = getelementptr float, ptr %p, %sub2
      %gep = getelementptr float, ptr %gep.base, 511

Obviously, reuniteExts treated a - b and b - a as equivalent.
This patch fixes that.

Chia-hung Duan [Fri, 10 Feb 2023 21:54:03 +0000 (21:54 +0000)]
[scudo] Add the thread-safety annotations

This CL adds the proper thread-safety annotations for most of the
functions and variables. However, given the restriction of the current
architecture, in some cases, we may not be able to use the annotations
easily. The followings are two exceptions,

1. enable()/disable(): Many structures in scudo are enabled/disabled by
   acquiring the lock in each instance. This makes those structure act
   like a `lock`. We can't mark those functions with ACQUIRE()/RELEASE()
   because that makes the entire allocator become another `lock`. In the
   end, that implies we need to *acquire* the `allocator` before each
   malloc et al. request. Therefore, adding a variable to tell the
   status of those structures may be a better way to cooperate with
   thread-safety annotation.

2. TSD/TSD shared/TSD exclusive: These three have simiar restrictions as
   mentioned above. In addition, they don't always need to be released
   if it's a thread local instance. However, thread-safety analysis
   doesn't support conditional branch. Which means we can't mark the
   proper annotations around the uses of TSDs. We may consider to make
   it consistent and which makes the code structure simpler.

This CL is supposed to introduce the annotations with the least code
refactoring. So only trivial thread safety issues will be addressed
here. For example, lacking of acquiring certain lock before accessing
certain variables will have the ScopedLock inserted. Other than that,
they are supposed to be done in the later changes.

[InstSimplify] fix/improve folding with an SNaN operand

There are 2 issues here:

1. In the default LLVM FP environment (regular FP math instructions),
   SNaN is some flavor of "don't care" which we will nail down in
   D143074, so this is just a quality-of-implementation improvement
   for default FP.
2. In the constrained FP environment (constrained intrinsics), SNaN
   must not propagate through a math operation; it has to be quieted
   according to IEEE-754 spec. That is independent of exception
   handling mode, so the current behavior is a miscompile.

[openmp] Fix building for mingw targets after import library changes

06d9bf5e64d472db5485815d9c3f70631064bb25 (https://reviews.llvm.org/D143431)
did a large restructuring of how the import library is created;
previously, a second step to tweak the import library was only
done for MSVC style targets, but after this commit, that logic
was applied for mingw targets too.

Since LIBOMP_GENERATED_IMP_LIB_FILENAME and LIBOMP_IMP_LIB_FILE
are equal on mingw targets (both are "libomp.dll.a", while they
are "libomp.dll.lib" and "libomp.lib" for MSVC targets), this caused
a conflict, with errors like this:

  ninja: error: build.ninja:875: multiple rules generate runtime/src/libomp.dll.a [-w dupbuild=err]

Skip the logic with a second step to recreate the import library
for mingw targets. The MSVC specific logic for this relies on
running the static archiver with CMAKE_LINK_DEF_FILE_FLAG, which
with MS lib.exe (and llvm-lib) ignore the input object files and
just generates an import library - but mingw style tools don't
support this mode of operation. (By attemptinig the same, mingw tools
would generate a static library with the def file as one member.)
With mingw tools, the same can be achieved by invoking the dlltool
executable instead.

Instead of adding alternative logic for invoking dlltool, just skip
the second import library step, since neither GNU nor LLVM mingw
tools actually generate import libraries that link by ordinal - so
there's no need for a second import library.

it can lead to spurious "... macro redefined" warnings when the defined macro
