The original line was there from when this test was added, but it is
checking for a switch that doesn't exist, so really has no purpose, at

The check against the output of `od` in the affected tests expect a
specific input offset format. They also expect a specific offset value,
not consistent with the EXAMPLE section for `od` in POSIX.1-2017
Chapter 4, while using the `-j` option. In particular, the example shows
that the input offset begins at 0 following the bytes skipped.
This patch adjusts the matching of the input offset to be more generic.
In order to avoid false matches, it restricts the number of bytes to be
formatted.

Summary:
This patch adds support for handling variables under the:
```
#pragma omp declare target to()
```
clause when the
```
#pragma omp requires unified_shared_memory
```
is used.
The address of the host variable is copied into the device pointer just like for the declare target link case.

Summary:
This patch applies a change similar to rC363069, but for SARIF files.
The `%diff_sarif` lit substitution invokes `diff` with a non-portable
`-I` option. The intended effect can be achieved by normalizing the
inputs to `diff` beforehand. Such normalization can be done with
`grep -Ev`, which is also used by other tests.
Additionally, this patch updates the SARIF output to have a newline at
the end of the file. This makes it so that the SARIF file qualifies as a
POSIX text file, which increases the consumability of the generated file
in relation to various tools.

Specify message levels in CMake. Prefer STATUS (stdout).
As the default message mode (i.e. level) is NOTICE in CMake, more then necessary messages get printed to stderr. Some tools, noticably ccmake treat this as an error and require additional confirmation and re-running CMake's configuration step.
This commit specifies a mode (either STATUS or WARNING or FATAL_ERROR) instead of the default.

Previously, we attempted to write out template parameters and specializations to their own array, but due to the architecture of the ASTNodeTraverser, this meant that other nodes were not being written out. This now follows the same behavior as the regular AST dumper and puts all the (correct) information into the "inner" array. When we correct the AST node traverser itself, we can revisit splitting this information into separate arrays again.

Summary:
This patch teaches ConstantFolding to constant fold
both scalar and vector variants of llvm.smul.fix and
llvm.smul.fix.sat.
As described in the LangRef rounding is unspecified for
these instrinsics. If the result cannot be represented
exactly the default behavior in ConstantFolding is to
round down towards negative infinity. If a target has a
preferred rounding that is different some kind of target
hook would be needed (same strategy as used by the
SelectionDAG legalizer).

Vector load/store instructions support an optional alignment field
that the compiler can use to provide known alignment info to the
hardware. If the field is used (and the information is correct),
the hardware may be able (on some models) to perform faster memory
accesses than otherwise.
This patch adds support for alignment hints in the assembler and
disassembler, and fills in known alignment during codegen.

Summary:
The first use of this is a code tweak to expand macro calls.
Will later be used to build syntax trees.

Using the -fdeclare-opencl-builtins option will require a way to
predefine types and macros such as `int4`, `CLK_GLOBAL_MEM_FENCE`,
etc. Move these out of opencl-c.h into opencl-c-base.h such that the
latter can be shared by -fdeclare-opencl-builtins and
-finclude-default-header.
This changes the behaviour of -finclude-default-header when
-fdeclare-opencl-builtins is specified: instead of including the full
header, it will include the header with only the base definitions.

Bug: https://bugs.llvm.org/show_bug.cgi?id=39024
The bug reports that a vectorized loop is stepped through 4 times and each step through the loop seemed to show a different path. I found two problems here:
A) An incorrect line number on a preheader block (for.body.preheader) instruction causes a step into the loop before it begins.
B) Instructions in the middle block have different line numbers which give the impression of another iteration.
In this patch I give all of the middle block instructions the line number of the scalar loop latch terminator branch. This seems to provide the smoothest debugging experience because the vectorized loops will always end on this line before dropping into the scalar loop. To solve problem A I have altered llvm::SplitBlockPredecessors to accommodate loop header blocks.
I have set up a separate review D61933 for a fix which is required for this patch.

Summary:
The test case does an (out of bounds) load from a global constant with
type <3 x float>. InstSimplify tried to turn this into an integer load
of the whole alloc size of the vector, which is 128 bits due to
alignment padding, and then bitcast this to <3 x vector> which failed
an assertion due to the type size mismatch.
The fix is to do an integer load of the normal size of the vector, with
no alignment padding.
