declaration and tracks the location. Diagnostic testing added for
invalid use of concept keyword.

Among other things, this makes clang-format understand arbitrary blocks
embedded in them, such as:
SomeFunction({MACRO({ return output; }), b});
where MACRO could e.g. expand to a lambda.

represented by uint64_t, this patch replaces these
usages with the FeatureBitset (std::bitset) type.

* Add in-memory object file handling to the core dynamic loader
* Fix in memory object file handling in ObjectFileELF (previously
only part of the file was loaded before parsing)
* Fix load address setting in ObjectFileELF for 32-bit targets
when the load bias is negative
* Change hack in DYLDRendezvous.cpp to be more specific and not to
interfere with object files with fixed load address

Add intrinsics for the FXSR instructions (FXSAVE/FXSAVE64/FXRSTOR/FXRSTOR64)
These were previously declared in Intrin.h for MSVC compatibility, but now
that we have them implemented, these declarations can be removed.

These instructions confusing the unwind code because in case of a
push it assumes that the original valu of a register is pushed to
the stack what is not neccessarily true in case of SP. The same is
true for the pop (in the opposite way).

This updated contains various changes to isl, including improvements to the
AST generator. For Polly, the most important change is a fix that unbreaks
builds on darwin (reported by: Jack Howard)

isTriviallyRecursive is a hack used to bridge a gap between the
expectations that source code assumes and the semantics that LLVM IR can
provide. Specifically, asm labels on functions are treated as an
explicit name for a GlobalObject in Clang but treated like an
output-processing step in GCC. Tweak this hack a little further to emit
calls to library functions instead of emitting an incorrect definition.
The definition in question would have available_externally linkage (this
is OK) but result in a call to itself which will either result in an
infinite loop or stack overflow.
This fixes PR23964.

This unbreaks TripleTest.Normalization. We'll have to come up with a new
plan for the OS component of the target triple for WebAssembly.

MSVC only genreates array cookies if the class has a destructor. This
is problematic when having to call T::operator delete[](void *, size_t)
because the second argument's argument is impossible to synthesize
correctly if the class has no destructor (because there will be no array
cookie).
Instead, MSVC passes the size of the class. Do the same, for
compatibility, instead of crashing.
This fixes PR23990.

Summary:
This diff introduces .rst files, Sphinx config, and a CMake target
for building clang man pages. This will deprecate the existing .pod-
based man page, and will integrate nicely with CMake. This diff does
not remove the existing man page; that will be done in a follow-up
once packagers have had a chance to react to the change.
For now, only clang(1) has been done; others can be added over time
by dropping additional files into the docs/CommandGuide directory.
The index page for CommandGuide has been copied from LLVM's
docs/CommandGuide.
The man page itself is mostly the same, with a few minor cosmetic
changes. The only major change is the SYNOPSIS section. I was unable
to get .rst/Sphinx produce the same style as in the existing man page.
Instead, I changed it to match the LLVM tools' relatively simple style.
To build the man pages, use the "docs-clang-man" target if building
with CMake. Otherwise, use "make -f Makefile.sphinx man".

Realistically, this will be returning ErrorOr for some time as refactoring the
user code to check once per section will take some time.
Given that, use it for checking if a relocation has addend or not.
While at it, add ELFRelocationRef to simplify the users.

A call to removeEmptySubranges() is necessary after every operation that
potentially removes all segments from a subregister range; this case in
the register coalescer was missing.

The size of this class actually matters because this is the
most popular class among all classes. We create a Defined symbol
for each defined symbol in a symbol table. That can be millions
for a large program. For example, linking LLD instantiates this
class millions times.
llvm-svn: 241025
If you only need Name and Value fields in the COFF symbol,
you don't need to distinguish 32 bit and 64 bit COFF symbols.
These fields start at the same offsets and have the same size.
This data strucutre is one pointer smaller than COFFSymbolRef
thus slightly efficient. I'll use this class in LLD as we create
millions of LLD symbol objects that currently contain COFFSymbolRef.
Shaving off 8 byte (or 4 byte on 32 bit) from that class actually
matters becasue of the number of objects we create in LLD.
llvm-svn: 241024
If a section is not SHT_REL or SHT_RELA, we never create a valid iterator,
so the getRelocation* methods should always see a section with the correct type.

Specifically, remove the dependent library interface and replace the existing
linker option interface with a new one that returns a single list of flags.

It is meant to be used to record modules @imported by the current
compile unit, so a debugger an import the same modules to replicate this
environment before dropping into the expression evaluator.
DIModule is a sibling to DINamespace and behaves quite similarly.
In addition to the name of the module it also records the module
configuration details that are necessary to uniquely identify the module.
This includes the configuration macros (e.g., -DNDEBUG), the include path
where the module.map file is to be found, and the isysroot.
The idea is that the backend will turn this into a DW_TAG_module.

Reapplies r241005 after fixing the build on non-Mac platforms. Original
commit message below.
The hostname can be very unstable when there are many machines on the
network competing for the same name. Using the hardware UUID makes it
less likely to have collisions or to consider files written by the
current host to be owned by a different one at a later time.
