LLVM does not and has not ever supported a soft-float ABI mode on
Sparc, so don't pretend that it does.
Also switch the default from "soft-float" -- which was actually
hard-float because soft-float is unimplemented -- to hard-float.

in section 10.1, __arm_{w,r}sr{,p,64}.
This includes arm_acle.h definitions with builtins and codegen to support
these, the intrinsics are implemented by generating read/write_register calls
which get appropriately lowered in the backend based on the register string
provided. SemaChecking is also implemented to fault invalid parameters.

Summary:
This affects other tools so the previous C++ API has been retained as a
deprecated function for the moment. Clang has been updated with a trivial
patch (not covered by the pre-commit review) to avoid breaking -Werror builds.
Other in-tree tools will be fixed with similar trivial patches.
This continues the patch series to eliminate StringRef forms of GNU triples
from the internals of LLVM that began in r239036.

Update ObjCContainersChecker to be notified when pointers escape so it can
remove size information for escaping CFMutableArrayRefs. When such pointers
escape, un-analyzed code could mutate the array and cause the size information
to be incorrect.

Some people want to experiment with building i686 CloudABI binaries. I
am not entirely sure this is a good idea, as I'd rather see Intel x32
support appear.
As it only requires a two-line change, let's at least provide compiler
to ease experimenting.

As noted on Errc.h:
// * std::errc is just marked with is_error_condition_enum. This means that
// common patters like AnErrorCode == errc::no_such_file_or_directory take
// 4 virtual calls instead of two comparisons.
And on some libstdc++ those virtual functions conclude that
------------------------
int main() {
std::error_code foo = std::make_error_code(std::errc::no_such_file_or_directory);
return foo == std::errc::no_such_file_or_directory;
}
-------------------------

Summary:
The goal of this patch is to make `-verify` easier to use when testing libc++. The `notes` attached to compile error diagnostics are numerous and relatively unstable when they reference libc++ header internals. This patch allows libc++ to write stable compilation failure tests by allowing unexpected diagnostic messages to be ignored where they are not relevant.
This patch adds a new CC1 flag called `-verify-ignore-unexpected`. `-verify-ignore-unexpected` tells `VerifyDiagnosticsConsumer` to ignore *all* unexpected diagnostic messages. `-verify-ignore-unexpected=<LevelList>` can be used to only ignore certain diagnostic levels. `<LevelList>` is a comma separated list of diagnostic levels to ignore. The supported levels are `note`, `remark`, `warning` and `error`.

seems like it's not the right concept anyway, as it fails on
`static const' in C, and will actually trigger the assert below on:

Summary:
In addition to easier syntax, IRBuilder makes sure to set correct
debug locations for newly added instructions (bitcast and
llvm.lifetime itself). This restores the original behavior, which
was modified by r234581 (reapplied as r235553).
Extend one of the tests to check for debug locations.

The underlying problem in PR23823 already existed before my recent change
in r239558, but that change made it worse (failing not only for undeclared
symbols, but also failed overload resolution). This makes Clang not try to
delay the lookup in SFINAE context. I assume no current code is relying on
SFINAE working with lookups that need to be delayed, because that never
seems to have worked.

If llvm.lifetime.end turns out to be the first instruction in the last
basic block, we can decrement the iterator twice, going past rend.
At the moment, this can never happen because llvm.lifetime.end always
goes immediately after bitcast, but relying on this is very brittle.

We were adding an extra "-mlinker-version" argument to the invocation
based on a value inferred from "ld -v". This is set by the build
systems to either a sane value or an empty string (e.g. for custom
built ld), which we don't want to pass on.
No test really possible because the value depends on both host system
and how CMake was invoked.

We would get this right in the case where an explicit cast was formed
but not when we were performing an implicit conversion.
This fixes PR23828.

Summary:
This patch removes useless whitespace in File path in index.html
Previously, a File directory path is copied and pasted as below:
arch /arm /kernel /stacktrace.c
It just removes the whitespace between directories and makes the
copied string as below:
arch/arm/kernel/stacktrace.c
The output looks same in html format, but the copied directory path
can be pasted as it looks.

Since we're ignoring the tune= and fpmath= attributes go ahead
and add a warning alerting people to the fact that we're going
to ignore that part of it during code generation and tie it to
the attribute warning set.
llvm-svn: 239583
Right now we're ignoring the fpmath attribute since there's no
backend support for a feature like this and to do so would require
checking the validity of the strings and doing general subtarget
feature parsing of valid and invalid features with the target
attribute feature.
llvm-svn: 239582
Modeled after the gcc attribute of the same name, this feature
allows source level annotations to correspond to backend code
generation. In llvm particular parlance, this allows the adding
of subtarget features and changing the cpu for a particular function
based on source level hints.
This has been added into the existing support for function level
attributes without particular verification for any target outside
of whether or not the backend will support the features/cpu given
(similar to section, etc).
