This skips all the lldb-vscode tests when running the test suite with
reproducers.

This reverts commit 1108f5c7.

This reverts commit 307e8539.

Summary:
Replace any extant metadata uses of a dying instruction with undef to
preserve debug info accuracy. Some alternatives include:

- Treat Instruction like any other Value, and point its extant metadata
  uses to an empty ValueAsMetadata node. This makes extant dbg.value uses
  trivially dead (i.e. fair game for deletion in many passes), leading to
  stale dbg.values being in effect for too long.

- Call salvageDebugInfoOrMarkUndef. Not needed to make instruction removal
  correct. OTOH results in wasted work in some common cases (e.g. when all
  instructions in a BasicBlock are deleted).

This came up while discussing some basic cases in
https://reviews.llvm.org/D80052.

Summary:
This patch fixes a problem when pmull2 instruction is not
generated for vmull_high_p64 intrinsic.

ISel has a pattern for int_aarch64_neon_pmull64 intrinsic to generate
PMULL2 instruction. That pattern assumes that extraction operations
are located in the same basic block. We need to sink them
if they are not. Handle operands of int_aarch64_neon_pmull64
into AArch64TargetLowering::shouldSinkOperands.

Buildbot has been failing since

This patch fix the minor issues that cause warnings.

PS4 supports these relocations types; so, we want to enable them by default.

Summary: With complex IR, the difference engine can enter an inconsistent state where the instruction and block difference engines return different results. Prevent a crash by refusing to pop beyond the end of the vector.

This commit increases the convenience of using the MsgPackDocument API,
especially when creating a document for writing out.

It adds direct assignment of bool, integer and string types to a
DocNode, as long as that DocNode is already inside a document, e.g. the
result of a map lookup. It also adds map lookup given an integer type
(it already had that for string).

So, to assign a string to a map element whose key is an int, you can
now write
  MyMap[42] = "towel";
instead of
  MyMap[MyMap.getDocument()->getNode(42)] =
      MyMap.getDocument()->getNode("towel");

Also added MapDocNode::erase methods.

Summary:
To support all targets, the mayAlias member function needs to support instructions with multiple operands.

This revision also changes the order of the emitted instructions in some test cases.

Promote alloca to vector before SROA and loop unroll. If we manage
to eliminate allocas before unroll we may choose to unroll less.

This assert just caught me, and this improved message would have saved
me some time.

The set of patterns for unpredicated load/store was incomplete: it only
included non-extending stores.  Fill out the remaining patterns for
extending stores, and add the corresponding support to frame offset
lowering.

The readFromBlob method can now be used to read MsgPack into a Document

This is a test commit as per Chris to verify commit access.

Thanks!

Fixes transposed names in comment.

Summary:
For some targets generic combines don't really do much and they
consume a disproportionate amount of time.
There's not really a mechanism in SDISel to tactically disable
combines, but we can have a switch to disable all of them and
let the targets just implement what they specifically need.

Reland [libc++] [LWG3321] Mark "year_month_day_last::day() specification does not cover !ok() values" issue as "Nothing to do", but add assertion.

Summary:
This LWG issue states that the result of `year_month_day_last::day()` is implementation defined if `ok()` is `false`.
However, from user perspective, calling `day()` in this situation will lead to a (possibly difficult to find) crash.
Hence, I have added an assertion to warn user at least when assertions are enabled.

Fixes warning: control reaches end of non-void function [-Wreturn-type]

Enable inset/extract/construct composite ops as well as access chain for
cooperative matrix. ConstantComposite requires more change and will be done in
a separate patch. Also fix the getNumElements function for coopMatrix per
feedback from Jeff Bolz. The number of element is implementation dependent so
it cannot be known at compile time.

Instead of linking the tests against a library in some version of the
SDK, always link against the latest library, but still run against the
specified back-deployment target dylib.

This makes more sense since what we're really trying to test is that
the current library can be used to produce binaries that run on some
deployment target -- not that linking against the library in some
previous SDK makes that possible.

This solves an additional issue that when linking against a system dylib,
the -rpath argument given to the tests is ignored because the install_name
of the system library we link against is absolute.

Summary:
Module::setProfileSummary currently calls addModuelFlag. This prevents from
updating the ProfileSummary metadata in the module and results in a second
ProfileSummary added instead of replacing an existing one. I don't think this is
the expected behavior. It prevents updating the ProfileSummary and it does not
make sense to have more than one. To address this, add Module::setModuleFlag and
use it from setProfileSummary.

Summary:
This patch fixes a bug where initialization code for .bss segments was
emitted in the memory initialization function even though the .bss
segments were discounted in the datacount section and omitted in the
data section. This was producing invalid binaries due to out-of-bounds
segment indices on the memory.init and data.drop instructions that
were trying to operate on the nonexistent .bss segments.
