Commit f8da95cd7e68ea66010843ef44adbe8d2807170c by leonardchan
[compiler-rt] Add shared_cxxabi requirement to some tests

This adds REQUIRES: shared_cxxabi to a bunch of tests that would fail if this
weak reference in sanitizer common was undefined. This is necessary in cases
where libc++abi.a is statically linked in. Because there is no strong reference
to __cxa_demangle in compiler-rt, then if libc++abi is linked in via a static
archive, then the linker will not extract the archive member that would define
that weak symbol. This causes a handful of tests to fail because this leads to
the symbolizer printing mangled symbols where tests expect them demangled.

Technically, this feature is WAI since sanitizer runtimes shouldn't fail if
this symbol isn't resolved, and linking statically means you wouldn't need to
link in all of libc++abi. As a workaround, we can simply make it a requirement
that these tests use shared libc++abis.

[ThinLTO] Update combined index for SamplePGO indirect calls to locals

In ThinLTO for locals we normally compute the GUID from the name after
prepending the source path to get a unique global id. SamplePGO indirect
call profiles contain the target GUID without this uniquification,
however (unless compiling with -funique-internal-linkage-names).

In order to correctly handle the call edges added to the combined index
for these indirect calls, during importing and bitcode writing we
consult a map of original to full GUID to identify the actual callee.
However, for a large application this was consuming a lot of compile
time as we need to do this repeatedly (especially during importing where
we may traverse call edges multiple times).

To fix this implement a suggestion in one of the FIXME comments, and
actually modify the call edges during a single traversal after the index
is built to perform the fixups once. I combined this fixup with the dead
code analysis performed on the index in order to avoid adding an
additional walk of the index. The dead code analysis is the first
analysis performed on the index.

This reduced the time required for a large thin link with SamplePGO by
about 20%.

No new test added, but I confirmed that there are existing tests that
will fail when no fixup is performed.

[InstCombine] fold lshr(trunc(lshr X, C1)) C2

Only the multi-use cases are changing here because there's
another fold that catches the simpler patterns.

But that other fold is the source of infinite loops when we
try to add D110170, so removing that is planned as a follow-up.

Attempt to show the general proof in Alive2:
https://alive2.llvm.org/ce/z/Ns1uS2

Note that the overshift fold-to-zero tests are not
currently handled by instsimplify. If they were, we
could assert that the shift amount sum is less than
the source bitwidth.

* It removes the weird duplication of generic parser/printer hooks,

[IR] Handle large element size when calculating GEP indices

This is a fix for the issue reported at
https://reviews.llvm.org/D110043#3019942:
The ElementSize is a uint64_t and as such may be larger than the
index space, or be negative in the index space. This is UB, but
shouldn't cause assertion failures.

We address this by detecting whether the size is too large and
use a zero index in that case (which is always conservatively
correct).

[SystemZ][z/OS] Introduce the GOFFMCAsmInfo Interface for z/OS

- This patch adds in the GOFFMCAsmInfo interfaces for the z/OS target.
- This patch decouples the previously existing SystemZMCAsmInfo interface for the ELF target and the z/OS target.
- This patch also removes a small test in the SystemZAsmLexerTest.cpp. The reason for this is because, the test is set up for the s390x-ibm-linux (SystemZ ELF triple), and the test checks a function which is overridden only for the z/OS target. The reason we can't change the test to use a z/OS triple outright is because there is still missing support which prevents the successful running of a test (assert in AsmParser.cpp due to missing GOFFAsmParser support)

[mlir] Create a generic reduction detection utility

This patch introduces a generic reduction detection utility that works
across different dialecs. It is mostly a generalization of the reduction
detection algorithm in Affine. The reduction detection logic in Affine,
Linalg and SCFToOpenMP have been replaced with this new generic utility.

The utility takes some basic components of the potential reduction and
returns: 1) the reduced value, and 2) a list with the combiner operations.
The logic to match reductions involving multiple combiner operations disabled
until we can properly test it.

[AutoFDO][llvm-profgen] Profile generation for LBR(non-CS) sample

This patch introduces non-CS AutoFDO profile generation into LLVM. The profile is supposed to be well consumed by compiler using `-fprofile-sample-use=[profile]`.

After range and branch counters are extracted from the LBR sample, here we go through each addresses for symbolization, create FunctionSamples and populate its sub fields like TotalSamples, BodySamples and HeadSamples etc. For inlined code, as we need to map back to original code, so we always add body samples to the leaf frame's function sample.

[AutoFDO][llvm-profgen] Report zero count for unexecuted part of function code

In order to be consistent with compiler that interprets zero count as unexecuted(cold), this change reports zero-value count for unexecuted part of function code. For the implementation, it leverages the range counter, initializes all the executed function range with the zero-value. After all ranges are merged and converted into disjoint ranges, the remaining zero count will indicates the unexecuted(cold) part of the function.

This change also extends the current `findDisjointRanges` method which now can support adding zero-value range.

[RISCV] Add another isel optimization for (and (shl X, c2), c1).

Where c1 is a shifted mask with 32-c2 leading zeros and c3 trailing
zeros and c3>c2. We can select it as (slli (srliw X, c3-c2), c3).

Fixed a bug in https://reviews.llvm.org/rG8eb617d719bdc6a4ed7773925d2421b9bbdd4b7a.

For compressed profile when reading an unknown section, the data reader pointer
adjustment was incorrect. This patch fixed that.

[llvm] Improve export.sh with help and snapshot

This change adds the ability to create source tarballs for unreleased or untagged code by providing the `--git-ref <GIT_REF>` flag to the `llvm/utils/release/export.sh` script. This is useful for creating daily snapshot tarballs that can easily be consumed by packagers who want to build a daily snapshot.

The default behavior of `export.sh` hasn't changed.

You may also provide a `--template` argument to say how the artifacts
are supposed to be named (as suggested by @hans).

The `-help` output of `export.sh` was changed quite significantly to look like this:

```
Export the Git sources and build tarballs from them.

Usage: export.sh [-release|--release <major>.<minor>.<patch>]
                      [-rc|--rc <num>]
                      [-final|--final]
                      [-git-ref|--git-ref <git-ref>]
                      [-template|--template <template>]

Flags:

  -release  | --release <major>.<minor>.<patch>    The version number of the release
  -rc       | --rc <num>                           The release candidate number
  -final    | --final                              When provided, this option will disable the rc flag
  -git-ref  | --git-ref <git-ref>                  (optional) Use <git-ref> to determine the release and don't export the test-suite files
  -template | --template <template>                (optional) Possible placeholders: $PROJECT $YYYYMMDD $GIT_REF $RELEASE $RC.
                                                   Defaults to '${PROJECT}-${RELEASE}${RC}.src.tar.xz'.

The following list shows the filenames (with <placeholders>) for the artifacts
that are being generated (given that you don't touch --template).

  * llvm-<RELEASE><RC>.src.tar.xz
  * clang-<RELEASE><RC>.src.tar.xz
  * compiler-rt-<RELEASE><RC>.src.tar.xz
  * libcxx-<RELEASE><RC>.src.tar.xz
  * libcxxabi-<RELEASE><RC>.src.tar.xz
  * libclc-<RELEASE><RC>.src.tar.xz
  * clang-tools-extra-<RELEASE><RC>.src.tar.xz
  * polly-<RELEASE><RC>.src.tar.xz
  * lldb-<RELEASE><RC>.src.tar.xz
  * lld-<RELEASE><RC>.src.tar.xz
  * openmp-<RELEASE><RC>.src.tar.xz
  * libunwind-<RELEASE><RC>.src.tar.xz
  * flang-<RELEASE><RC>.src.tar.xz

Additional files being generated:

  * llvm-project-<RELEASE><RC>.src.tar.xz    (the complete LLVM source project)
  * test-suite-<RELEASE><RC>.src.tar.xz      (only when not using --git-ref)

To ease the creation of snapshot builds, we also provide these files

  * llvm-release-<YYYYMMDD>.txt        (contains the <RELEASE> as a text)
  * llvm-rc-<YYYYMMDD>.txt             (contains the rc version passed to the invocation of export.sh)
  * llvm-git-revision-<YYYYMMDD>.txt   (contains the current git revision sha1)

Example values for the placeholders:

  * <RELEASE>  -> 13.0.0
  * <YYYYMMDD> -> 20210414
  * <RC>       -> rc4        (will be empty when using --git-ref)

In order to generate snapshots of the upstream main branch you could do this for example:

  export.sh --git-ref upstream/main --template '${PROJECT}-${YYYYMMDD}.src.tar.xz'

```
