This should be the last step in the current cleanup.
Follow-ups should resolve the TODO about cost calc
and enable the more general case where we extract
different elements.
Summary:
This change allows a hard coded relative PYTHONHOME setting. So that
python can easily be packaged together with lldb.
The change includes:
1. Extend LLDB_RELOCATABLE_PYTHON to all platforms. It defaults to ON
for platforms other than Windows, to keep the behavior compatible.
2. Allows to customize LLDB_PYTHON_HOME. But still defaults to
PYTHON_HOME.
3. LLDB_PYTHON_HOME can be a path relative to liblldb. If it is
relative, we will resolve it before send it to Py_DecodeLocale.

This moves all the logic of converting LLVM Triples to
MachO::CPU_(SUB_)TYPE from the specific target (Target)AsmBackend to
more convenient functions in lib/BinaryFormat.
This also gets rid of the separate two X86AsmBackend classes.
The previous attempt was to add it to libObject, but that adds an
unnecessary dependency to libObject from all the targets.

isPrefix was added to support the patches to align branches.
it relies on a switch over instruction names.
This moves those opcodes to a new format so the information is
tablegen and we can just check for a specific value in some bits
in TSFlags instead.
I've left the other function in place for now so that the
existing patches in phabricator will still work. I'll work with
the owner to get them migrated.
Summary:
Added register + immediate and register + register addressing modes for the following intrinsics:
1. Masked load and stores:
* Sign and zero extended load and truncated stores.
* No extension or truncation.
2. Masked non-temporal load and store.

By default the RISC-V target doesn't have the atomics standard extension
enabled. The first RUN line in `clang/test/CodeGen/atomic_ops.c` didn't
specify a target triple, which meant that on RISC-V Linux hosts it would
target RISC-V, but because it used clang cc1 we didn't get the toolchain
driver functionality to automatically turn on the extensions implied by
the target triple (riscv64-linux includes atomics). This would cause the
test to fail on RISC-V hosts.
This patch changes the test to have RUN lines for two explicit targets,
one with native atomics and one without. To work around FileCheck
limitations and more accurately match the output, some tests now have
separate prefixes for the two cases.

Otherwise, the `availability=XXX` lit feature is set even when we're
testing trunk and _LIBCPP_DISABLE_AVAILABILITY is defined, which causes
tests that check for availability markup to be enabled and unexpectedly
pass.
The legalizer helper functions are unusably awkward to perform the 3-5
part legalization. This needs to be widened, scalarized, lowered, and
we should avoid creating vector extends and truncates. Manually do all
of this and expand.
Summary:
The purpose of this patch is to make identifying missing dependencies clearer to the user.
`find_package` will report if a package is not found, that output, combined with the exiting
status message, is clearer than not having the additional verbosity.
If the SWIG dependency is required {LLDB_ENABLE_PYTHON, LLDB_ENABLE_LUA}
and SWIG is not available, fail the configuration step. Terminate the
configure early rather than later with a clear error message.
We could possibly modify:
`llvm-project/lldb/cmake/modules/FindPythonInterpAndLibs.cmake`
However, the patch here seems clear in my opinion.

I tried to use some of the new tablegen features to avoid creating
different operand list permutations, but I still don't see a way to
programmatically build a source pattern dag.
Also add GlobalISel tests, which now all import successfully.
Some of the fneg fold tests are incorrect, which need to be fixed in a
future commit
G_SHUFFLE_VECTOR is legal since it theoretically may help match op_sel
for VOP3P instructions. Expand it in some other way in case it doesn't
fold into the use instructions.
Summary:
When we have a long name for the undefined symbol, we would hit this assertion:
Assertion failed: I != StringIndexMap.end() && "String is not in table!"
This patch addresses that.

This patch implements the RFCs proposed here:
https://llvm.discourse.group/t/rfc-modify-ifop-in-loop-dialect-to-yield-values/463https://llvm.discourse.group/t/rfc-adding-operands-and-results-to-loop-for/459/19.
It introduces the following changes:
- All Loop Ops region, except for ReduceOp, terminate with a YieldOp.
- YieldOp can have variadice operands that is used to return values out of IfOp and ForOp regions.
- Change IfOp and ForOp syntax and representation to define values.
- Add unit-tests and update .td documentation.
- YieldOp is a terminator to loop.for/if/parallel
- YieldOp custom parser and printer
Lowering is not supported at the moment, and will be in a follow-up PR.

This fixes a small mistake from D72944: The worklist add should
happen before assigning the new operand, not after.
In case an actual replacement happens, the old operand needs to
be added for DCE. If no actual replacement happens, then old/new
are the same, so it doesn't matter.
This drops one iteration from the annotated test case.
Summary:
This prevents BFI queries on new blocks (from
MachineSinking::GetAllSortedSuccessors) and fixes a bunch of assert failures
under -check-bfi-unknown-block-queries=true.

The Blocks runtime provide a header named Block.h.
It is generally preferable to avoid name collision with system headers
(reducing reliance on -isystem order, more friendly when navigating files in

This changes the SimplifyLibCalls utility to accept an IRBuilderBase,
which allows us to pass through the IRBuilder used by InstCombine.
This will ensure that new instructions get added to the worklist.
The annotated test-case drops from 4 to 2 InstCombine iterations thanks
to this.
To achieve this, I'm adding an IRBuilderBase::OperandBundlesGuard,
which is basically the same as the existing InsertPointGuard and
FastMathFlagsGuard, but for operand bundles. Also add a
setDefaultOperandBundles() method so these can be set outside the
constructor.

A cost query for a vector instruction should return a cost even without
target vector support, and not trigger an assert.
VectorCombine does this with an input containing source code vectors.
Review: Ulrich Weigand
We don't use this, and matching from the def doesn't make much sense.
There are multiple tablegen bugs with default operand
handling. undef_tied_input should work to handle the vdst_in
correctly, but this breaks the operand register class constraint which
it should be able to infer.
Summary:
This revision adds matchers that match calls to the gtest EXPECT and ASSERT
macros almost like function calls. The matchers are placed in separate files
(GtestMatchers...), because they are specific to the gtest library.

We should try the generated matchers before the manual selection. This
means the patterns are now handling the common cases, but the manual
selection code is not yet dead. It's still handling the non-s32/s64
cases (like v2s16 and v2s32). Currently tablegen doesn't have a nice
way to have a single pattern that covers multiple types.
