Nico Weber a16ba6fea2 Reland "Make it possible for lit.site.cfg to contain relative paths, and use it for llvm and clang"
The problem on Windows was that the \b in "..\bin" was interpreted
as an escape sequence. Use r"" strings to prevent that.

This reverts commit ab11b9eefa,
with raw strings in the lit.site.cfg.py.in files.

Nico Weber fb80b6b2d5 Make it possible for lit.site.cfg to contain relative paths, and use it for llvm and clang
Currently, all generated lit.site.cfg files contain absolute paths.

This makes it impossible to build on one machine, and then transfer the
build output to another machine for test execution. Being able to do
this is useful for several use cases:

1. When running tests on an ARM machine, it would be possible to build
   on a fast x86 machine and then copy build artifacts over after building.

2. It allows running several test suites (clang, llvm, lld) on 3
   different machines, reducing test time from sum(each test suite time) to
   max(each test suite time).

This patch makes it possible to pass a list of variables that should be
relative in the generated lit.site.cfg.py file to
configure_lit_site_cfg(). The lit.site.cfg.py.in file needs to call
`path()` on these variables, so that the paths are converted to absolute
form at lit start time.

The testers would have to have an LLVM checkout at the same revision,
and the build dir would have to be at the same relative path as on the
builder.

This does not yet cover how to figure out which files to copy from the
builder machine to the tester machines. (One idea is to look at the
`--graphviz=test.dot` output and copy all inputs of the `check-llvm`
target.)

Simon Tatham 6a946993d5 Do export symbols when LLVM_EXPORT_SYMBOLS_FOR_PLUGINS is on.
Summary:
In D76527, we stopped exporting symbols from clang, opt and llc unless
the `LLVM_ENABLE_PLUGINS` cmake variable is true (which causes clang's
own plugin collection to be built).

But another reasonable build configuration is to ask clang to export
its symbols for out-of-tree plugins to use, without building the
in-tree ones. That is, you might set `LLVM_EXPORT_SYMBOLS_FOR_PLUGINS`
without also setting `LLVM_ENABLE_PLUGINS` (at least if you're using
MSVC, where you need to ask explicitly for the symbols to be
exported).

In that situation, the symbols should still be exported, but after
D76527, they weren't being.

Petr Hosek 71a2a62163 [CMake] Pass symlink dependency to add_llvm_install_targets explicitly
The install-${name}-stripped targets don't strip when ${name} is being
symlinked, e.g. llvm-ar or llvm-objcopy. The problem is that
llvm_install_symlink passes install-${dest} as a dependency of
install-${name}, e.g. install-llvm-ar becomes a dependency of both
install-llvm-ranlib and install-llvm-ranlib-stripped. What this means is
that when installing a distribution that contains both llvm-ar and
llvm-ranlib is that first the stripped version of llvm-ar is installed
(by the install-llvm-ar-stripped target) and then it's overwritten by an
unstripped version of llvm-ar bnecause install-llvm-ranlib-stripped has
install-llvm-ranlib as a dependency as mentioned earlier. To avoid this
issue, rather than passing the install-${dest} as dependency, we
introduce a new argument to add_llvm_install_targets for symlink target
which expands it into an appropriate dependency, i.e. install-${dest}
for install-${name} target and install-${dest}-stripped for
install-${name}-stripped.

serge_sans_paille 24ab9b537e Generalize the pass registration mechanism used by Polly to any third-party tool
There's quite a lot of references to Polly in the LLVM CMake codebase. However
the registration pattern used by Polly could be useful to other external
projects: thanks to that mechanism it would be possible to develop LLVM
extension without touching the LLVM code base.

This patch has two effects:

1. Remove all code specific to Polly in the llvm/clang codebase, replaicing it
   with a generic mechanism

2. Provide a generic mechanism to register compiler extensions.

A compiler extension is similar to a pass plugin, with the notable difference
that the compiler extension can be configured to be built dynamically (like
plugins) or statically (like regular passes).

As a result, people willing to add extra passes to clang/opt can do it using a
separate code repo, but still have their pass be linked in clang/opt as built-in
passes.

Tom Stellard ab411801b8 [cmake] Explicitly mark libraries defined in lib/ as "Component Libraries"
Summary:
Most libraries are defined in the lib/ directory but there are also a
few libraries defined in tools/ e.g. libLLVM, libLTO.  I'm defining
"Component Libraries" as libraries defined in lib/ that may be included in
libLLVM.so.  Explicitly marking the libraries in lib/ as component
libraries allows us to remove some fragile checks that attempt to
differentiate between lib/ libraries and tools/ libraires:

1. In tools/llvm-shlib, because
llvm_map_components_to_libnames(LIB_NAMES "all") returned a list of
all libraries defined in the whole project, there was custom code
needed to filter out libraries defined in tools/, none of which should
be included in libLLVM.so.  This code assumed that any library
defined as static was from lib/ and everything else should be
excluded.

With this change, llvm_map_components_to_libnames(LIB_NAMES, "all")
only returns libraries that have been added to the LLVM_COMPONENT_LIBS
global cmake property, so this custom filtering logic can be removed.
Doing this also fixes the build with BUILD_SHARED_LIBS=ON
and LLVM_BUILD_LLVM_DYLIB=ON.

2. There was some code in llvm_add_library that assumed that
libraries defined in lib/ would not have LLVM_LINK_COMPONENTS or
ARG_LINK_COMPONENTS set.  This is only true because libraries
defined lib lib/ use LLVMBuild.txt and don't set these values.
This code has been fixed now to check if the library has been
explicitly marked as a component library, which should now make it
easier to remove LLVMBuild at some point in the future.

I have tested this patch on Windows, MacOS and Linux with release builds
and the following combinations of CMake options:

- "" (No options)
- -DLLVM_BUILD_LLVM_DYLIB=ON
- -DLLVM_LINK_LLVM_DYLIB=ON
- -DBUILD_SHARED_LIBS=ON
- -DBUILD_SHARED_LIBS=ON -DLLVM_BUILD_LLVM_DYLIB=ON
- -DBUILD_SHARED_LIBS=ON -DLLVM_LINK_LLVM_DYLIB=ON

Chris Bieneman 760a9ee63c Support codesigning bundles and forcing
Summary:
Clangd's framework is assembled by copying binaries from the lib and bin directories into a bundle shape. This results in an invalid bundle code signature because the signature only applies to the binaries not the resources.

This patch adds two new options to `llvm_codesign` to enable re-signing the library and XPC service as bundles.

The `BUNDLE_PATH` option allow specifying an explicit path to codesign, which enables signing bundles which aren't generated using CMake's `FRAMEWORK` or `BUNDLE` target properties.

The `FORCE` option allows re-signing binaries that have already been signed. This is required for how clangd exposes the clangd library and tools as both XPC and non-XPC services using the same binary.

Summary:
Extra flexibility for emitting debug info to external files (remains Darwin only for now).
LLDB needs this functionality to emit a LLDB.framework.dSYM instead of LLDB.dSYM when building the framework, because the latter could conflict with the driver's lldb.dSYM when emitted in the same directory on case-insensitive file systems.

Shoaib Meenai 19c45546fc [cmake] Reset variable before using it
A bunch of macros use the same variable name, and since CMake macros
don't get their own scope, the value persists across macro invocations,
and we can end up exporting targets which shouldn't be exported. Clear
the variable before each use to avoid this.

Converting these macros to functions would also help, since it would
avoid the variable leaking into its parent scope, and that's something I
plan to follow up with. It won't fully address the problem, however,
since functions still inherit variables from their parent scopes, so if
someone in the parent scope just happened to use the same variable name
we'd still have the same issue.

Michal Gorny d4b194cf95 [cmake] Fix get_llvm_lit_path() to respect LLVM_EXTERNAL_LIT always
Refactor the get_llvm_lit_path() logic to respect LLVM_EXTERNAL_LIT,
and require the fallback to be defined explicitly
as LLVM_DEFAULT_EXTERNAL_LIT. This fixes building libcxx standalone
after r346888.

The old logic was using LLVM_EXTERNAL_LIT both as user-defined cache
variable and an optional pre-definition of default value from caller
(e.g. libcxx). It included a hack to make this work by assigning
the value back and forth but it was fragile and stopped working
in libcxx.

The new logic is simpler and more transparent. Default value is
provided in a separate variable, and used only when user-specified
variable is empty (i.e. not overriden).

Chris Bieneman db49209c90 [CMake] Use LLVM_ENABLE_IDE instead of CMAKE_CONFIGURATION_TYPES
There are several places where we use CMAKE_CONFIGURATION_TYPES to determine if we are using an IDE generator and in turn decide not to generate some of the convenience targets (like all the install-* and check-llvm-* targets). This decision is made because IDEs don't always deal well with the thousands of targets LLVM can generate.

This approach does not work for Visual Studio 15's new CMake integration. Because VS15 uses a Ninja generator, it isn't a multi-configuration build, and generating all these extra targets mucks up the UI and adds little value.

With this change we still don't generate these targets by default for Visual Studio and Xcode generators, and LLVM_ENABLE_IDE becomes a switch that can be enabled on the VS15 CMake builds, to improve the IDE experience.

This is a re-land of r340435, with a few minor fix-ups. The issues causing the revert were addressed in r344218, r344219, and r344553.

to remove this from the path.  This in turn means that the path

Occasionally it is useful to have unittest which take inputs.
While we normally try to have this test be more of a lit test
we occasionally don't have tools that can exercise the code
in the right way to test certain things.  LLDB has been using
this style of unit test for a while, particularly with regards
to how it tests core dump and minidump file parsing.  Recently
i needed this as well for the case where we want to test that
some of the PDB reading code works correctly.  It needs to
exercise the code in a way that is not covered by any dumper
and would be impractical to implement in one of the dumpers,
but requires a valid PDB file.  Since this is now needed by
more than one project, it makes sense to have this be a
generally supported thing that unit tests can do, and we just
encourage people to use this sparingly.

The current version does not utilize LLVM LNT and LLVM CMake

introduced CMake variables:

* `LLVM_INCLUDE_BENCHMARKS` (`ON` by default) generates benchmark
  targets
* `LLVM_BUILD_BENCHMARKS` (`OFF` by default) adds generated
  benchmark targets to the list of default LLVM targets (i.e. if `ON`
  benchmarks will be built upon standard build invocation, e.g. `ninja` or
  `make` with no specific targets)

* `BENCHMARK_ENABLE_EXCEPTIONS` is disabled
* `BENCHMARK_ENABLE_INSTALL` is disabled
* `BENCHMARK_ENABLE_GTEST_TESTS` is disabled

Shoaib Meenai fce4616189 [cmake] Add linker detection for Apple platforms
LLVM currently assumes that Apple platforms will always use ld64. In the
future, LLD Mach-O might also be supported, so add the beginnings of
linker detection support. ld64 is currently the only detected linker,
since `ld64.lld -v` doesn't yield any useful version output, but we can
add that detection later, and in the meantime it's still useful to have
the ld64 identification.

Switch clang's order file check to use this new detection rather than
just checking for the presence of an ld64 executable.

Petr Hosek 47550bb1d6 [CMake] Use CMAKE_OBJCOPY and CMAKE_STRIP to externalize debug info
Don't hardcode objcopy and strip names, rather use CMAKE_OBJCOPY and
CMAKE_STRIP variables which allows users to override the tools used
such as using llvm-objcopy and llvm-strip instead of binutils versions.

Shoaib Meenai fd7befad23 [cmake] Make linker detection take flags into account
LLVM might be compiled using a toolchain file which controls the linker
to use via flags (e.g. `-B` or `-fuse-ld=`). Take these flags into
account for linker detection. We can also correct the detection by
manually passing LLVM_USE_LINKER, of course, but it seems more
convenient to have the detection take flags into account.

Nico Weber 79c6ec484e Rename Attributes.gen, Intrinsics.gen to Attributes.inc, Intrinsics.inc
Virtually all other tablegen outputs are called .inc, not .gen, so rename these two too for consistency.
No behavior change.

Sylvestre Ledru f22ebb7599 Rename llvm library from libLLVM-X.Y to libLLVM-X
Summary:
As we are only doing X.0.Z releases (not using the minor version), there is no need to keep -X.Y in the version.

Like patch https://reviews.llvm.org/D41808, I propose that we rename libLLVM-7.0svn.so to libLLVM-7svn.so 
This patch will also rename downstream libraries like liblldb-7.0 to liblldb-7

Michal Gorny 93176a813a [cmake] Append -Wl,-rpath-link conditionally to GNULD
Append -Wl,-rpath-link conditionally to whether GNU ld.bfd is used
rather than the Linux+!gold conditionals. Also move it out of 'else'
branch of *BSD handling. This fixes build failures with ld.bfd
on Gentoo/FreeBSD, and should cause no harm on other systems using
ld.bfd.

This patch improves the original logic by reusing results of linker
detection introduced in r307852.

Shoaib Meenai 1295088fba [cmake] Use symlinks for Windows-hosted toolchains built on Unix
When cross-compiling for Windows on Unix, the built toolchain will need
to be transferred to Windows to actually run. My opinion is that the
Unix build should use symlinks, and the transfer to Windows should take
care of making those symlinks usable. E.g., I envision tarballs to be a
common form of transfer from Unix to Windows, in which case the tarball
can be created using --dereference to follow the symlinks.

The motivation here is that, when cross-compiling for Windows on Unix,
the installation will *already* create symlinks. The reason is that the
installation script will be invoked without knowing the host system, so
the `if(UNIX)` check in the installation symlink creation script will
reflect the build system rather than the host system. We could either
make the build and install trees both contain copies or both contain
symlinks, and using symlinks is a significant space saving without (in
my opinion) having any detrimental effect on the usage of the cross-
compiled toolchain on Windows.

A secondary motivation is that Windows 10 version 1703 and later finally
lift the administrator rights requirement for creating symbolic links
(if the system is in Developer Mode), which makes symlinks a lot more
practical even on Windows. Of course Unix and Windows symlinks aren't
interoperable, but symlinks for Windows toolchains is a reasonable
future direction to be going in anyway.
