The existing logic for per-target libc++ include directories only
seem to exist for the Gnu and Fuchsia drivers, added in
ea12d779bc / D89013.
This is less generic than the corresponding case in the Gnu driver,
but matches the existing level of genericity in the MinGW driver
(and others too).

Consistently use 'w64' as vendor string; it was 'pc' for the original
i686 triple added in 91bd6c922d, but the later x86_64 triple
used 'w64' as vendor, added in d6c1f37f86.
When the arm triples were added in c84ad73a27, the differing
vendors were copied over accidentally to the arm targets too.
When using per-target runtime directories, having inconsistent vendor
parts of the target triples is fatal.

In e72403f96d, we added the flag
"--no-dynamicbase" for disabling the dynamicbase flag which we set
by default. At the time, ld.bfd didn't have any corresponding
option (as ld.bfd defaulted to not setting the flag). Almost at
the same time, corresponding options were added to ld.bfd for
disabling it (while it was being enabled by default), with a
different name, "--disable-dynamicbase".
Thus add the "--disable-dynamicbase" option. Make this default
one advertised in the help listing, but keep the "--no-dynamicbase"
form as an alias. Also improve checking for the last option set
if there are multiple ones on the same command line.
Also add corresponding disable options for a lot of other flags
that we set by default, also added in ld.bfd in the same commit:

a1ef81de35 adjusted the definition of the intrinsic, but did not
update a PowerPC test. Fix the test by updating the call & declaration
of @llvm.matrix.column.major.load.
As for now, llvm-objcopy sorts section headers according to the offsets
of the sections in the input file. That can corrupt section references
in the dynamic symbol table because it is a loadable section and as such
is not updated by the tool. Even though the section references are not
required for loading the binary correctly, they are still handy for a
user who analyzes the file.
While the patch removes global reordering of section headers, it layouts
the sections in the same way as before, i.e. according to their original
offsets. All that helps the output file to resemble the input better.
Note that the patch removes sorting SHT_GROUP sections to the start of
the list, which was introduced in D62620 in order to ensure that they
come before the group members, along with the corresponding test. The
original issue was caused by the sorting of section headers, so dropping
the sorting also resolves the issue.

This patch adjusts the intrinsics definition of
llvm.matrix.column.major.load and llvm.matrix.column.major.store to
allow overloading the type of the stride. The bitwidth of the stride is
used to perform the offset computation.
This fixes a crash when using __builtin_matrix_column_major_load or
__builtin_matrix_column_major_store on 32 bit platforms. The stride argument
of the builtins are defined as `size_t`, which is 32 bits wide on 32 bit
platforms.
Note that we still perform offset computations with 64 bit width on 32
bit platforms for accesses that do not take a user-specified stride.
This can be fixed separately.
Fixes PR51304.

This patch enables extending loads for fixed length SVE code generation.
There is a slight regression here in the mulh tests; since these tests
load the parameter and then extend it these are treated as extending
loads which are merged, preventing the mulh instruction from being
generated. As this affects scalable SVE codegen as well this should be
addressed in a separate patch.

The patch in http://reviews.llvm.org/D106431 landed in commit
4a097efe77 to the main branch.
However, this patch was also backported to upcoming release 13.0.0 in
commit 8dcdfc0de84f60b5b4af97ac5b357881af55bc6e, which makes this entry
in the release notes **NOT** a new thing for the purposes of 14.0.0.
After
9da70ab3d4
we saw a few regressions around trailing attribute definitions and in
typedefs (examples in the added test cases). There's some tension
distinguishing K&R definitions from attributes at the parser level,
where we have to decide if we need to put the type of the K&R definition
on a new unwrapped line before we have access to the rest of the line,
so we're scanning backwards and looking for a pattern like f(a, b). But
this type of pattern could also be an attribute macro, or the whole
declaration could be a typedef itself. I updated the code to check for a
typedef at the beginning of the line and to not consider raw identifiers
as possible first K&R declaration (but treated as an attribute macro
instead). This is not 100% correct heuristic, but I think it should be
reasonably good in practice, where we'll:
* likely be in some very C-ish code when using K&R style (e.g., stuff
that uses `struct name a;` instead of `name a;`
* likely be in some very C++-ish code when using attributes
* unlikely mix up the two in the same declaration.
Ideally, we should only decide to add the unwrapped line before the K&R
declaration after we've scanned the rest of the line an noticed the
variable declarations and the semicolon, but the way the parser is
organized I don't see a good way to do this in the current parser, which
only has good context for the previously visited tokens. I also tried
not emitting an unwrapped line there and trying to resolve the situation
later in the token annotator and the continuation indenter, and that
approach seems promising, but I couldn't make it to work without
messing up a bunch of other cases in unit tests.

These two tests, TestSkinnyCorefile.py and TestStackCorefile.py,
require a new debugserver on darwin systems to run correctly; for now,
skip them if the system debugserver is in use. There's no easy way to
test if the debugserver being used supports either of these memory
region info features. For end users, the fallback will be a full
corefile and that's not the worst thing, but for the tests it is a
problem.
These rules were originally written when the new predicate based legalizer
was introduced in an attempt to preserve existing behaviour. It wasn't
properly kept up to date as things like vector support was split out into
G_CONCAT_VECTORS, and frankly, even if it was, it was too complex.
It's much easier to start from scratch with what we can actually support,
which is just a few type combinations. Anything illegal we should either
legalize, or should be eliminated as a side effect of artifact combination.

Currently we use a centralized string map(StringMap<FunctionSamples> ProfileMap) to store the profile while populating the sample, which might cause the memory usage bottleneck. I saw in an extreme case, there are thousands of samples whose context stack depth is >= 100. The memory consumption can be greater than 100GB.
As here the context is used for inlining, we can assume we won't have so many of inlinees keeping inlined at the same root function, so this change tried to cap the context stack and merge the samples for peak memory reduction and this is done after recursion compression.
The default value is -1 meaning no depth limit, in the future we can tune to a smaller one.

AssertionError: False is not True

This is a workaround until https://reviews.llvm.org/D81892 is merged
and the internal Lit shell stops conflating error output with normal
output. Without this, any program that writes to stderr will trip up
the programOutput function, because it will pick up the '# command stderr:'
string and think it's part of the command's stdout.
