The approach here is to create a new (empty) component, `Extensions', where all
statically compiled extensions dynamically register their dependencies. That way
we're more natively compatible with LLVMBuild and llvm-config.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
At some point we and/or CMake changed our build-mode-style builds from
$LLVM_OBJ_ROOT/bin/$CMAKE_CFG_INTDIR/
to
$LLVM_OBJ_ROOT/$CMAKE_CFG_INTDIR/bin/
which is way easier to use. But no one updated llvm-config.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and

Summary:
r327219 added wrappers to std::sort which randomly shuffle the container before sorting.
This will help in uncovering non-determinism caused due to undefined sorting
order of objects having the same key.
To make use of that infrastructure we need to invoke llvm::sort instead of std::sort.
Note: This patch is one of a series of patches to replace *all* std::sort to llvm::sort.

`LLVM_TOOLS_INSTALL_DIR` was introduced in r272200 in order to override the directory

This fixes the out-of-tree clang standalone build for me.

The code parsing the string was using the offset returned from
StringRef::find() wrong, assuming it was relative to the staring
offset that is passed to the function, but the returned offset
is always relative to the beginning of the line.
This causes odd behaviour while parsing the component string.
Spotted thanks to the newly added test:
tools/llvm-config/booleans.test
llvm-svn: 291803
Following the similar change to lit configuration, ensure that all CMake
booleans are canonicalized to 0/1 when being passed to llvm-config. This
fixes the incorrect interpretation of values when user passes another
value than the ON/OFF, and simplifies the code by removing unnecessary
string matching.
Furthermore, the code for --has-rtti and --has-global-isel has been
modified to print consistent values indepdently of the boolean used by
passed by the user to CMake. Sadly, the code already implicitly used
different values for the two (YES/NO for --has-rtti, ON/OFF for
--has-global-isel).
Include tests for all booleans and multi-value options in llvm-config.

Modify the --system-libs option in llvm-config to print system libs only
when using static linking. The system libraries are irrelevant when
linking to a shared library since the library has appropriate library
dependencies embedded.
Modify the --system-libs test appropriately to force static linking, and
disable it if static libs are not available (i.e. BUILD_SHARED_LIBS is
enabled).

Add a --cmakedir option to llvm-config that returns the correct path to

incorrect output when LLVM is built with `LLVM_BUILD_LLVM_DYLIB`.
`llvm-config` previously produced output like this
```
$ llvm-config --libfiles
/usr/lib/liblibLLVM-4.0svn.so.so
$ llvm-config --libnames
liblibLLVM-4.0svn.so.so
```
The library prefix and shared library extension were added to
the library name twice which was wrong.
I wanted to write a test cases for this but it looks like **all**
`llvm-config` tests were disabled by r260386 so I'll leave this for

Summary:
This is a re-commit of r257003, which was reverted,
along with the fixes from http://reviews.llvm.org/D15986.
r252532 added support for reporting the monolithic library
when LLVM_BUILD_LLVM_DYLIB is used. This would only be done
if the individual components were not found, and the dynamic
library is found.
This diff extends this as follows:
- If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared
library, even if all component libraries exist.
- Two flags, --link-shared and --link-static are introduced
to provide explicit guidance. If --link-shared is passed
and the shared library does not exist, an error results.
Additionally, changed the expected shared library names from
(e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an
installation (and then only in CMake builds I think?), and not
in the build tree; this breaks usage of llvm-config during
builds, e.g. by llvm-go.

Summary:
This patch does a couple of things:
- Adds a new argument `--shared-mode` which accepts a list of components and prints whether or not the provided components need to be linked statically or shared.
- Fixes `--libnames` when CMake BUILD_SHARED_LIBS is used.
- Fixes `--libnames`, `--libs`, and `--libfiles` for dylib when static components aren't installed.
- Fixes `--libnames`, `--libs`, `--libfiles`, and `--components` to use LLVM_DYLIB_COMPONENTS as the component manifest for dylib linking.
- Uses the host platform's usual convention for filename extensions and such, instead of always defaulting to Unix-izms.
Because I don't own a Mac, I am not able to test the Mac platform dependent stuff locally. If someone would be willing to run a build for me on their machine (unless there's a better option), I'd appreciate it.

Summary:
This prints NO if LLVM was built with -fno-rtti or an equivalent flag
and YES otherwise. The reasons to add -has-rtti rather than adding -fno-rtti
to --cxxflags are:
1. Building LLVM with -fno-rtti does not always mean that client
applications need this flag.
2. Some compilers have a different flag for disabling rtti, and the
compiler being used to build LLVM may not be the compiler being used to
build the application.

It seems I was wrong thinking `autoconf`/`make` only installed shared libraries if configured with `--enable-shared`, even if `--disable-static` is present. I'll re-address with a followup patch.
This reverts commit r243297 for causing PR#24154.
llvm-svn: 244108
Summary:
When LLVM is configured to build shared libraries, CMake builds each component as it's own shared object, while autoconfig/make builds them statically and then links them all together to create a single shared object. This change adds compile time config flags to `llvm-config` so it can know whether LLVM's components are separated or not and act accordingly.
This fixes `llvm-config` instead of fixing the makefiles to behave like CMake because, AIUI, LLVM's autoconfig/make build system is on the way out anyway.
This change only affects `llvm-config` from builds that use autoconfig/make.

For this to work, we have to encode it in the build variables and use it
from llvm-config.cpp. I've tried to do this reasonably cleanly, but the
code for llvm-config.cpp is pretty strange. However, with this,
llvm-config stops giving the wrong answer when using LLVM_LIBDIR_SUFFIX.
Note that the configure+make build just sets this to an empty string as
that build system has zero support for multilib of any form. I'm not
planning to add support there either, but this should leave a path for
anyone that wanted to.

Previously llvm-config --system-libs would print something like:

Now we don't emit blank line. Functionality is unchanged otherwise, in
particular llvm-config --libs --system-libs still emits the LLVM libraries
and the system libraries on different lines.
