Stephan T. Lavavej 1738e9d649 [libcxx] [test] Change ifstream constructor tests to handle read-only files.
Certain source control systems like to set the read-only bit on their files,
which interferes with opening "test.dat" for both input and output.
Fortunately, we can work around this without losing test coverage.
Now, the ifstream.cons tests have comments referring to the ofstream.cons tests.
There, we're creating writable files (not checked into source control),
where the ifstream constructor tests will succeed.

Fixes D26814.

Mehdi Amini ef27db879c Refactor BitcodeReader: move Metadata and ValueId handling in their own class/file
Summary:
I'm planning on changing the way we load metadata to enable laziness.
I'm getting lost in this gigantic files, and gigantic class that is the bitcode
reader. This is a first toward splitting it in a few coarse components that
are more easily understandable.

Dimitry Andric 59e5cb4342 Fix compile with GCC 5 or later
Summary:

Compiling with GCC 5 or later can fail with a bogus error "constructor
required before non-static data member for
llvm::ValueEnumerator::MDRange::First has been parsed".

This was originally fixed upstream in GCC PR 70528, but later this fix
was reverted, and released versions of GCC still show the bogus error.

To work around this, replace MDRange's declaration of a default
constructor with a definition.

Filipe Cabecinhas 322ecd901b [clang] Version support for UBSan handlers
This adds a way for us to version any UBSan handler by itself.
The patch overrides D21289 for a better implementation (we're able to
rev up a single handler).

After this, then we can land a slight modification of D19667+D19668.

We probably don't want to keep all the versions in compiler-rt (maybe we
want to deprecate on one release and remove the old handler on the next
one?), but with this patch we will loudly fail to compile when mixing
incompatible handler calls, instead of silently compiling and then
providing bad error messages.

Teresa Johnson 040cc16835 [ThinLTO] Import only necessary DICompileUnit fields
Summary:
As discussed on mailing list, for ThinLTO importing we don't need
to import all the fields of the DICompileUnit. Don't import enums,
macros, retained types lists. Also only import local scoped imported
entities. Since we don't currently import any global variables,
we also don't need to import the list of global variables (added an
assert to verify none are being imported).

This is being done by pre-populating the value map entries to map
the unneeded metadata to nullptr. For the imported entities, we can
simply replace the source module's list with a new list containing
only those needed imported entities. This is done in the IRLinker
constructor so that value mapping automatically does the desired
mapping.

Michal Gorny f4debddb09 [Driver] Fix finding multilib gcc install on Gentoo (with gcc-config)
Fix the gcc-config code to support multilib gcc installs properly. This
solves two problems: -mx32 using the 64-bit gcc directory (due to matching
installation triple), and -m32 not respecting gcc-config at all (due to
mismatched installation triple).

In order to fix the former issue, split the multilib scan out of
Generic_GCC::GCCInstallationDetector::ScanLibDirForGCCTriple() (the code
is otherwise unchanged), and call it for each installation found via
gcc-config.

In order to fix the latter issue, split the gcc-config processing out of
Generic_GCC::GCCInstallationDetector::init() and repeat it for all
triples, including extra and biarch triples. The only change
in the gcc-config code itself is adding the call to multilib scan.

Convert the gentoo_linux_gcc_multi_version_tree test input to multilib
x86_64+32+x32 install, and add appropriate tests to linux-header-search
and linux-ld.

Daniel Jasper 03a04fe95f clang-format: Separate out a language kind for ObjC.
While C(++) and ObjC are generally formatted the same way and can be
mixed, people might want to choose different styles based on the
language. This patch recognizes .m and .mm files as ObjC and also
implements a very crude detection of whether or not a .h file contains
ObjC code. This can be improved over time.

Also move most of the ObjC tests into their own test file to keep file
size maintainable.

Craig Topper f2c6f7abf3 [X86] Change CMPSS/CMPSD intrinsic instructions to use sse_load_f32/f64 as its memory pattern instead of full vector load.
These intrinsics only load a single element. We should use sse_loadf32/f64 to give more options of what loads it can match.

Currently these instructions are often only getting their load folded thanks to the load folding in the peephole pass. I plan to add more types of loads to sse_load_f32/64 so we can match without the peephole.

Craig Topper 081c0e2864 [X86] Remove some intrinsic instructions from hasPartialRegUpdate
Summary:
These intrinsic instructions are all selected from intrinsics that have well defined behavior for where the upper bits come from. It's not the same place as the lower bits.

As you can see we were suppressing load folding for these instructions in some cases. In none of the cases was the separate load helping avoid a partial dependency on the destination register. So we should just go ahead and allow the load to be folded.

Only foldMemoryOperand was suppressing folding for these. They all have patterns for folding sse_load_f32/f64 that aren't gated with OptForSize, but sse_load_f32/f64 doesn't allow 128-bit vector loads. It only allows scalar_to_vector and vzmovl of scalar loads to match. There's no reason we can't allow a 128-bit vector load to be narrowed so I would like to fix sse_load_f32/f64 to allow that. And if I do that it changes some of these same test cases to fold the load too.
