Fangrui Song 7f7cb79b57 [llvm-cov gcov] Don't suppress .gcov output if .gcda is corrupted
If .gcda is corrupted, gcov continues to produce a .gcov and just
assumes execution counts are zeros. This is reasonable, because the
program can corrupt its .gcda output. The code path should be similar to
the code path without .gcda.

Daniel Sanders e35ba09961 [gicombiner] Allow generated combiners to store additional members
Summary:
Adds the ability to add members to a generated combiner via
a State base class. In the current AArch64PreLegalizerCombiner
this is used to make Helper available without having to
provide it to every call.

As part of this, split the command line processing into a
separate object so that it still only runs once even though
the generated combiner is constructed more frequently.

Depends on D81862

Christopher Tetreault b3e77c6d55 [SVE] Remove invalid calls to VectorType::getNumElements from BasicTTIImpl
Summary:
Most of these operations are reasonable for scalable vectors. Due to
this, we have decided not to change the interface to specifically take
FixedVectorType despite the fact that the current implementations make
fixed width assumptions. Instead, we cast to FixedVectorType and assert
in the body. If a developer makes some change in the future that causes
one of these asserts to fire, they should either change their code or
make the function they are trying to call handle scalable vectors.

Fangrui Song def2156389 [gcov] Add -i --intermediate-format
Between gcov 4.9~8, `gcov -i $file` prints coverage information to
$file.gcov in an intermediate text format (single file, instead of
$source.gcov for each source file).

lcov newer than 2019-05-24 detects -i support and uses it to increase
processing speed.  gcov 9 (GCC r265587) removed --intermediate-format
and -i was changed to mean --json-format. However, we consider this
format still useful and support it. geninfo (part of lcov) supports this

Summary:

static data like an additional helper. Another patch will follow to

Alex Zinenko b4bc72afb7 [mlir] refactor Linalg LoopNestBuilder to use common infra
Recent work has introduced support for constructing loops via `::build` with
callbacks that construct loop bodies using only the core OpBuilder. This is now
supported on all loop types that Linalg lowers to. Refactor LoopNestBuilder in
Linalg to rely on this functionality instead of using a custom EDSC-based
approach to creating loop nests.

The specialization targeting parallel loops is also simplified by factoring out
the recursive call into a separate static function and considering only two
alternatives: top-level loop is parallel or sequential.

This removes the last remaining in-tree use of edsc::LoopBuilder, which is now
deprecated and will be removed soon.

Similar to binops, we are avoiding scalarization of a loaded
value because that could avoid a register transfer in codegen.
This requires 1 extra predicate that I am aware of: we do not
want to scalarize the condition value of a vector select. That
might also invert a transform that we do in instcombine that
prefers a vector condition operand for a vector select.

The Standard documents the signature of std::advance as

Furthermore, it does not appear to put any restriction on what the type
of Distance should be. While it is understood that it should usually
be std::iterator_traits::difference_type, I couldn't find any wording
that mandates that. Similarly, I couldn't find wording that forces the
distance to be a signed type.

This patch changes std::advance to accept any type in the second argument,
which appears to be what the Standard mandates. We then coerce it to the
iterator's difference type, but that's an implementation detail.
