Enable partial and runtime unrolling with a threshold of 30, which
was derived from a large number of kernels running on node and
wasmtime for amd64 and aarch64.

Unrolling is enabled by default at -O2 and -O3 and is disabled at
-Oz and -Os. Compiling with -Os is recommended if the wasm binary
size is the most important factor.

Similar to the case for G_ADD.

There was a function in CTMark/pairlocalalign which was missing this case,
causing GlobalISel to emit a add + csel when a csinc is all that is necessary.

Minor code size improvements on CTMark at -Os.

This reverts commit 3500cc8d.

This old commit was made over a completely false premise. OSSymbols
aren't different from other OSObjects and we shouldn't treat them
differently for the purposes of static analysis.

Previously broadcast was a binary op. Now it can support more inputs.
This has been changed in such a way that for now, this is an NFC for
all broadcast operations that were previously legal.

Even though it has some oddities, both pipelines should be as similar as
possible. Also use report_fatal_error instead of assertions to ensure a
proper failure in release builds for unsupported options.

This finalizes the patch serious to make Polly run in the default
configuration when using the NewPM by default.

In particular, print the ast with -debug-only=polly-ast, print a
per-scop header with print<polly-ast> and force-add the analysis with
-polly-code-generation=ast.

1. LegacyPM: Rename SimplifyLegacyPass to SimplifyWrapperPass.
2. LegacyPM: Complete create/init functions in LinkAllPasses.h
3. NewPM: Only invalidate non-Scop passes if changed.
4. NewPM: Add to default pass pipeline.
5. NewPM: Print -analyze header for each print<polly-simplify>

TargetTransformInfo is required by IslScheduleOptimizer, as ScopPass.
Unfortunately it is not possible to get arbitrary larger-unit analyses
in for as ScopPass. Loop passes also already use TargetTransformInfo as
LoopStandardAnalysisResults, hence wei might expect it to be available
to Scop passes as well.

The pass-instrumentation pass is implicitly execute by the NewPM
whenever a new analysis runs. Not registering it will cause the crash
whenever a scop pass requests an analysis.

For instance this is the case for the IstAstAnalysis requesting the
DependenceAnalsis result.

glibc deprecates `mallinfo` in the latest version of 2.33. This patch replaces the usage of `mallinfo` with the new `mallinfo2` when it's available.

They are analogous to the existing tests, but use different starting offset
which can be important for some transforms.

Since ToolChain::GetCXXStdlibType() is a simple getter that might emit
the "invalid library name in argument" warning, it can conceivably be
called several times while initializing the build pipeline.

Before this patch, a simple 'clang++ -stdlib=foo ./test.cpp' would print
the warning twice, -rt=lib=foo would print 6 times.

Change this and always only print the warning once. Keep the rest of the
semantics of the functions.

These are similar to maxnum and minnum, but they're defined to treat -0
as less than +0.  This behavior can't be expressed using float
comparisons and selects, since comparisons are defined to treat
different-signed zeros as equal.  So, the only way to communicate this
behavior into LLVM IR without defining target-specific intrinsics is to
add the corresponding ops.

Previously it reported an op had side-effects iff it declared that it
didn't have any side-effects.  This had the undesirable result that
canonicalization would always delete any intrinsic calls that did memory
stores and returned void.

This reverts commit 5eb2e994.

In addition to that regression tests should not test the intire pass
pipeline (unless they are testing the pipeline itself), the Polly-ACC
currently does not support the new pass manager. If enabled by default,
such tests will therefore fail.

Use the -polly-gpu-runtime and -polly-gpu-arch options also as default
values for the PPCGCodeGeneration pass. This requires to move the option
to be moved from the pipeline-building Register passes to the
PPCGCodeGeneration implementation.

Fixes the spir-typesize.ll buildbot fail.

BlockPointerSyntheticFrontEnd does a CopyType which results in it copying the type
back into its own context. This will result in a call to ASTImporterDelegate::setOrigin
with &decl->getASTContext() == origin.ctx this can result in an infinite recursion
later on in ASTImporter since it will attempt to find the decl in its origin which will be itself.

The code previously assumed that `getChunk` would return a non-null pointer for
every symbol, but in fact it only returns non-null pointers for DefinedFunction
and DefinedData symbols. This patch fixes the segfault by checking whether
`getChunk` returns a null for each symbol and skipping the mapping output for
any symbols for which it does.

Differential Revision: https://reviews.llvm.org/D96189

This revision adds a new `AliasAnalysis` class that represents the main alias analysis interface in MLIR. The purpose of this class is not to hold the aliasing logic itself, but to provide an interface into various different alias analysis implementations. As it evolves this should allow for users to plug in specialized alias analysis implementations for their own needs, and have them immediately usable by other analyses and transformations.

This revision also adds an initial simple generic alias, LocalAliasAnalysis, that provides support for performing stateless local alias queries between values. This class is similar in scope to LLVM's BasicAA.

Merging directories and files may produce different results on different
platforms.

Merging "./Inputs" and "source-interleave-x86_64.c" will use different
separators in POSIX and Windows.

Dedicated tests are needed for dealing with removing trailing separators
for POSIX (consider only '/') and Windows (consider '/' and '\').
