This covers:
* usual arithmetic conversions (comparisons, arithmetic, conditionals)
between different enumeration types
* usual arithmetic conversions between enums and floating-point types
* comparisons between two operands of array type
The deprecation warnings are on-by-default (in C++20 compilations); it
seems likely that these forms will become ill-formed in C++23, so
warning on them now by default seems wise.
For the first two bullets, off-by-default warnings were also added for
all the cases where we didn't already have warnings (covering language
modes prior to C++20). These warnings are in subgroups of the existing
-Wenum-conversion (except that the first case is not warned on if either
enumeration type is anonymous, consistent with our existing
-Wenum-conversion warnings).
If you don't do this you end up running arbitrary code with
only one thread allowed to run, which can cause deadlocks.

Summary:
[libomptarget][nfc] Wrap cuda min() in target_impl
nvptx forwards to cuda min, amdgcn implements directly.
Sufficient to build parallel.cu for amdgcn, added to CMakeLists.
All call sites are homogenous except one that passes a uint32_t and an
int32_t. This could be smoothed over by taking two type parameters
and some care over the return type, but overall I think the inline
<uint32_t> calling attention to what was an implicit sign conversion
is cleaner.

Summary: With the new LLVM_ENABLE_RUNTIMES option introduced in https://reviews.llvm.org/D40233, compiler-rt can now be included as a runtime. Since compiler-rt is needed for PGO, runtimes needs to be included as a dependency of clang-bootstrap-deps when building the stage1 compiler.

Summary:
This is needed because on some platforms we can't install signal
handlers and so the application just traps (i.e. crashes) rather than being intercepted
by ASan's signal handler which in the default Darwin config doesn't
exit with a crashing exit code.

This patch de-duplicates most compressed pair constructors
to use the same code in C++11 and C++03.
Part of doing that is deleting the "__second_tag()" and replacing
it with a "__value_init_tag()" which has the same effect, but
allows for the removal of the special "one-arg" first element
constructor.
This patch is intended to have no semantic change.
This patch makes it so that cases where multiple instructions that
differ only in their ConstantInt or ConstantFP MachineOperand values no
longer collide. For instance:
%0:_(s1) = G_CONSTANT i1 true
%1:_(s1) = G_CONSTANT i1 false
%2:_(s32) = G_FCONSTANT float 1.0
%3:_(s32) = G_FCONSTANT float 0.0
Prior to this patch the first two instructions would collide together.
Also, the last two G_FCONSTANT instructions would also collide. Now they
will no longer collide.

Currently -fuse-init-array option is not effective when target triple
does not specify os, on x86,x86_64.
i.e.
// -fuse-init-array is not honored.
$ clang -target i386 -fuse-init-array test.c -S
// -fuse-init-array is honored.
$ clang -target i386-linux -fuse-init-array test.c -S
This patch fixes first case.
And does cleanup.

Differential Revision: https://reviews.llvm.org/D71493
Summary:
In https://reviews.llvm.org/D62550 @rsmith pointed out that there are
many situations in which a coroutine body statement may be
transformed/rebuilt as part of a template instantiation, and my naive
check whether the coroutine was a generic lambda was insufficient.
This is indeed true, as I've learned by reading more of the
TreeTransform code. Most transformations are written in a way that
doesn't assume the resulting types are not dependent types. So the
assertion in 'TransformCoroutineBodyStmt', that the promise type must no
longer be dependent, is out of place.
This patch removes the assertion, spruces up some code comments, and
adds a test that would have failed with my naive check from
https://reviews.llvm.org/D62550.

If you set LLDB_TABLEGEN_EXE in a CMake cache file or in the CMake
invocation line, your setting isn't respected. Setting up the tablegen
for the host will overwrite the value that we set LLDB_TABLEGEN_EXE to,
which defeats the whole point of setting it in the first place.
This change introduces the __default_init_tag to memory, and a corresponding
element constructor to allow for default initialization of either of the pair
values. This is useful for classes such as std::string where most (all)
constructors explicitly initialize the values in the constructor.

This reverts commit b1e542f302.
The original 'hack' didn't chop out fp-16 to double conversions, so
systems that use FP16ConversionIntrinsics end up in IR-CodeGen with an
i16 type isntead of a float type (like PPC64-BE). The bots noticed
this.
Reverting until I figure out how to fix this

This skips calling `pthread_self` when `main_thread_identity` hasn't
been initialized yet. `main_thread_identity` is only ever assigned in
`__tsan::InitializePlatform`. This change should be relatively safe; we
are not changing behavior other than skipping the call to `pthread_self`
when `main_thread_identity == 0`.

dependent template names.
Apparently we didn't test this in the test suite because we have
a lot of redundant ways of representing this situation that kick
in in the more common situations. For example, DependentTST stores
a qualifier + identifier pair rather than a TemplateName.
The FP-classification builtins (__builtin_isfinite, etc) use variadic
packs in the definition file to mean an overload set. Because of that,
floats were converted to doubles, which is incorrect. There WAS a patch
to remove the cast after the fact.
THis patch switches these builtins to just be custom type checking,
calls the implicit conversions for the integer members, and makes sure
the correct L->R casts are put into place, then does type checking like
normal.
A future direction (that wouldn't be NFC) would consider making
conversions for the floating point parameter legal.
Summary:
This patch restricts loop fusion to only consider rotated loops as valid candidates.
This simplifies the analysis and transformation and aligns with other loop optimizations.

Summary:
The instructions were originally implemented via builtins and
intrinsics so users would have to explicitly opt-in to using
them. This was useful while were validating whether these instructions
should have been merged into the spec proposal. Now that they have
been, we can use normal codegen patterns, so the intrinsics and
builtins are no longer useful.

The %update_cc_test_checks substitution only gets added if python3
is on path, so the test fails if it isn't. Don't run the test
when it would fail.
Also include the '%' in the arg to add_update_script_substition(),
to help greppability.
This change only affects EM_386. relOff can be computed from `index`
easily, so it is unnecessarily passed as a parameter.
Both in.plt and in.iplt entries are written by writePLT. For in.iplt,
the instruction `push reloc_offset` will change because `index` is now
different. Fortunately, this does not matter because `push; jmp` is only
used by PLT. IPLT does not need the code sequence.
