This pattern inlines operands to a linalg.generic operation that use a constant
index and hence are loop-invariant scalars. This reduces the number of
linalg.generic operands and unlocks some canonicalizations that rely on seeing
an explicit tensor.extract.

There already exists cl_khr_fp64 extension. So OpenCL C 3.0
and higher should use the feature, earlier versions still
use the extension. OpenCL C 3.0 API spec states that extension
will be not described in the option string if corresponding
optional functionality is not supported (see 4.2. Querying Devices).
Due to that fact the usage of features for OpenCL C 3.0 must
be as follows:
```
$ clang -Xclang -cl-ext=+cl_khr_fp64,+__opencl_c_fp64 ...
$ clang -Xclang -cl-ext=-cl_khr_fp64,-__opencl_c_fp64 ...
```
e.g. the feature and the equivalent extension (if exists)
must be set to the same values

All the lit tests pass on linux (with lldb), and I've tested this on windows

Hi,
I am new to LLVM, and I really want to get involved in LLVM community.
I guess if the following switch case of function
TransformNestedNameSpecifierLoc could possibly made more beautiful with
'break' stmt moved inside of the right brace.
I think move of 'break' stmt will not change the invoking destructor of
IdInfo.
Thanks for your effort.

This reapplies c0f3dfb9, which was reverted following the discovery of
crashes on linux kernel and chromium builds - these issues have since
been fixed, allowing this patch to re-land.
This reverts commit 4397b7095d.
The previous rule:
(insert_vector _, (extract_vector X, 0), 0) -> X
is not quite correct. The correct fold should be:
(insert_vector Y, (extract_vector X, 0), 0) -> X
where: Y is X, or Y is undef
This commit updates the pattern.

In the WebAssembly target, we would like to allow alloca in two address
spaces. The alloca instruction already has an address space argument,
but the verifier asserts that the address space of an alloca is the
default alloca address space from the datalayout. This patch removes
this restriction. Targets that would like to impose additional
restrictions should do so via target-specific verification passes.

[Debugify][Original DI] Test dbg var loc preservation
This is an improvement of [0]. This adds checking of
original llvm.dbg.values()/declares() instructions in
optimizations.
We have picked a real issue that has been found with
this (actually, picked one variable location missing
from [1] and resolved the issue), and the result is
the fix for that -- D100844.
Before applying the D100844, using the options from [0]
(but with this patch applied) on the compilation of GDB 7.11,
the final HTML report for the debug-info issues can be found
at [1] (please scroll down, and look for

The Unit test was failing because the pass from the test that
modifies the IR, in its runOnFunction() didn't return 'true',
so the expensive-check configuration triggered an assertion.
The Loop start instruction handled by the ARMLowOverheadLoops are:
$lr = t2DoLoopStart $r0
$lr = t2DoLoopStartTP $r1, $r0
$lr = t2WhileLoopStartLR $r0, %bb, implicit-def dead $cpsr
All three of these will have LR as the 0 argument, the trip count as the
1 argument.
This patch updated a few places in ARMLowOverheadLoops where the 0th arg
was being used for t2WhileLoopStartLR instructions as the trip count.
One place was entirely removed as it does not seem valid any more, the
case the code is trying to protect against should not be able to occur
with our correct-by-construction low overhead loops.

Some systems use a different data layout. For instance, s390x the layout of
machines with vector registers is different from the ones without. In such
cases, the JIT will automatically detect the vector registers and go out of
sync.
This patch tells the JIT what is the target triple of the generated code so that
both ends are in sync.

This patch changes how line labels are resolved in order to enable
label-relative offsets to be used in commands. This is a breaking change in
dexter. Instead of using label references directly as argument values, labels
will instead be referenced through a function `ref(str)`.
// No way to use offsets currently.
Currently: DexExpectWatchValue('x', '1', on_line='labled_line')
Patched: DexExpectWatchValue('x', '1', on_line=ref('labled_line'))
Patched: DexExpectWatchValue('x', '1', on_line=ref('labled_line') + 3)
A dexter command is "parsed" by finding the whole command and sending it off to
`eval`. This change adds a function called `ref` to the `eval` globals map that
simply looks up the name and returns an int. If the line name hasn't been
defined, or a name is defined more than once, an error is reported (see
err_bad_label_ref.cpp and err_duplicate_label.cpp). Label offsets can be
achieved by simply writing the desired expression.
The rationale behind removing the existing label referencing mechanic is for
consistency and to simplify the code required to make labels work.
I've separated the update to llvm's dexter tests into another patch for ease of
review here (D101148). Here is a small python script which can be used to
update tests to use the new syntax:
https://gist.github.com/OCHyams/8255efe7757cac266440ed2ba55f1442
If it helps anyone using dexter on downstream tests we can come up with a
deprecation plan instead out outright removing the existing syntax.

Other LLVM projects use the suffix `-depends` for the test dependencies,
however LLDB uses `-deps` and seems to be the only project under the
LLVM to do so.
In order to make the projects more homogeneous, switch all the
references to `lldb-test-deps` to `lldb-test-depends`.
Additionally, provide a compatibility target with the old name and
depending on the new name, in order to not break anyone workflow.

were not allowed although corresponding numbers could be converted to
double without loss of precision. The similar restriction applied to

With this change any APFloat that can be precisely represented by double
can be handled with convertToDouble. Behavior of convertToFloat was
updated similarly. It make the conversion operations more convenient and
adds support for formats like half and bfloat.
