There is no supported toolchain which provides headers / libs / object
files specific to the mips32r[3|5] and mips64r[3|5] ISA. So select "r2"
specific folders when they are available.

Use the newly minted `DIImportedEntity` default constructor (r230609)
rather than explicitly specifying `nullptr`. The latter will become
ambiguous when the new debug info hierarchy is committed, since we'll
have both of the following:
explicit DIImportedEntity(const MDNode *);
DIImportedEntity(const MDImportedEntity *);
(Currently we just have the former.)
A default constructor is just as clear.
llvm-svn: 230610
Also remove the somewhat misleading initializers from
VectorizationFactor and VectorizationInterleave. They will get
initialized with the default ctor since no cl::init is provided.

Fix for PR22017. Integer template arguments are automatically bit extended to
the size of the integer type. In template diffing, evaluated expressions were
not having their results extending, leading to comparing two APSInt's with
different widths. Apply the proper bit extending when evaluating template
arguments. This mainly affected bool template arguments.

When I originally committed the statepoint docs, I left placeholders for example IR fragments. I'm finally getting around to filling those in.
I also added IR fragments to illustrate the usage of the PlaceSafepoints pass while I was at it.

are now:
FrontendTool -> StaticAnalyzer/Frontend -> Frontend -> StaticAnalyzer/Core
The final dependency edge here is probably removable: AnalyzerOptions (and
Analyses.def) should probably live in Basic rather than StaticAnalyzer/Core.

We'd diagnose an __assume expression which contained a function call.
This would result in us wrongly returning ExprError, causing mysterious
failures later on.

Executors can be specified at configure time by using the -DLIBCXX_EXECUTOR=""
option. Examples include:
$ cmake <other_flags> -DLIBCXX_EXECUTOR="TimeoutExecutor(30,LocalExecutor())"
This runs individual tests with a maximum duration
$ cmake <other_flags> -DLIBCXX_EXECUTOR="SSHExecutor('hostname','username')"
This runs tests on a remote target, using scp to shuttle binaries to the
target, and ssh to invoke commands there.
$ cmake <other_flags> -DLIBCXX_EXECUTOR="PrefixExecutor('/path/to/run/script',LocalExecutor())"
This assumes the script knows how to copy run the executables passed to it,
and allows for the ultimate control. This is useful for running things
inside emulators like Valgrind & QEMU.
TODO: This doesn't claim to support ShTest tests yet, that will take a bit more
thought & finagling (I'm still not sure how to orchestrate copy-in for those cases.
I've also punted on what to do about tests that read data files. The testsuite
has several tests that need to read *.dat files placed next to them, and
currently those aren't copied over when using, say, an SSHExecutor. The
affected tests are:

libc++ :: std/localization/locales/locale.convenience/conversions/conversions.buffer/underflow.pass.cpp
Note: One thing to watch out for when using the SSHExecutor for cross-testing is
that you'll also want to specify a TargetInfo object (so that the host's
features aren't used for available-features checks and flags setup).

Use the IRBuilder helpers for gc.statepoint and gc.result, instead of
coding the construction by hand. Note that the gc.statepoint IRBuilder
handles only CallInst, not InvokeInst; retain that part of hand-coding.

Currently -fms-extensions controls this behavior, which doesn't make
much sense. It means we can't identify what is and isn't a system header
when compiling our own preprocessed output, because #line doesn't
represent this information.
If someone is feeding Clang's preprocessed output to another compiler,
they can use this flag.
Fixes PR20553.

Explanation: This function is in TargetLowering because it uses
RegClassForVT which would need to be moved to TargetRegisterInfo
and would necessitate moving isTypeLegal over as well - a massive
change that would just require TargetLowering having a TargetRegisterInfo
class member that it would use.
llvm-svn: 230585
This required plumbing a TargetRegisterInfo through computeRegisterProperties
and into findRepresentativeClass which uses it for register class
iteration. This required passing a subtarget into a few target specific
initializations of TargetLowering.

Do not declare sized deallocation functions dependently on whether it is found in global scope. Instead, enforce the branching in emitted code by (1) declaring the functions extern_weak and (2) emitting sized delete expressions as a branching between both forms delete.

Add a brief section linking to the experimental statepoint intrinsics analogous to the one we have linking to patchpoint.
While I'm here, cleanup some wording about what the gc "name" attribute actually means. It's not the name of a *collector* it's the name of the *strategy* which may be compatible with multiple collectors.

This symbol exists only to pull in the required pieces of the runtime,
so nothing ever needs to refer to it. Making it hidden avoids the
potential for issues with duplicate symbols when linking profiled
libraries together.

Remove a newline from `AssemblyWriter::printMDNodeBody()`, and add one
to `AssemblyWriter::writeMDNode()`. NFCI for assembly output.
However, this drops an inconsistent newline from `Metadata::print()`
when `this` is an `MDNode`. Now the newline added by `Metadata::dump()`
won't look so verbose.

This is a follow-on to r227491 which tightens the check for propagating FP
values. If a non-constant value happens to be a zero, we would hit the same
bug as before.
Bug noted and patch suggested by Eli Friedman.

When we have a debug map we have an executable with a bunch of STAB symbols and each source file has a N_SO symbol which scopes a bunch of symbols inside of it. We can use this to our advantage here when looking for the complete definition of an objective C class by looking for a symbol whose name matches the class name and whose type is eSymbolTypeObjCClass. If we find one, that symbol will be contained within a N_SO symbol. This symbol gets turned into a symbol whose type is eSymbolTypeSourceFile and that symbol will contain the eSymbolTypeObjCClass which helps us to locate the correct .o file and allows us to only look in that file.
To further accelerate things, if we are looking for the implementation, we can avoid looking at all .o files if we don't find a matching symbol because we have a debug map, which means the objective C symbol for the class can't have been stripped, so we can safely not search all remaining .o files. This will save us lots of time when trying to look for "NSObject" and any other AppKit and Foundation classes that we never have implementation definitions for.

Summary: SROA generates code that isn't quite as easy to optimize and contains unusual-sized shuffles, but that code is generally correct. As discussed in D7487 the right place to clean things up is InstCombine, which will pick up the type-punning pattern and transform it into a more obvious bitcast+extractelement, while leaving the other patterns SROA encounters as-is.
