Fangrui Song b497665d98 Reland D64327 [MC][ELF] Allow STT_SECTION referencing SHF_MERGE on REL targets
This drops a GNU gold workaround and reverts the revert commit rL366708.

  Before binutils 2.34, gold -O2 and above did not correctly handle R_386_GOTOFF to
  SHF_MERGE|SHF_STRINGS sections: https://sourceware.org/bugzilla/show_bug.cgi?id=16794

From the original review:

  ... it reduced the size of a big ARM-32 debug image by 33%. It contained ~68M
  of relocations symbols out of total ~71M symbols (96% of symbols table was
  generated for relocations with symbol).

-Wl,-O2 (and -Wl,-O3) is so rare that we should just lower the
optimization level for LLVM_LINKER_IS_GOLD rather than pessimizing all users.

Mircea Trofin 62841415e6 [llvm] Added support for stand-alone cmake object libraries.
Summary:
Currently, add_llvm_library would create an OBJECT library alongside
of a STATIC / SHARED library, but losing the link interface (its
elements would become dependencies instead). To support scenarios
where linking an object library also brings in its usage
requirements, this patch adds support for 'stand-alone' OBJECT
libraries - i.e. without an accompanying SHARED/STATIC library, and
maintaining the link interface defined by the user.

This is useful for cases where, for example, we want to build a part
of a component separately. Using a STATIC target would incur the risk
that symbols not referenced in the consumer would be dropped (which may
be undesirable).

The current application is the ML part of Analysis. It should be part
of the Analysis component, so it may reference other analyses; and (in
upcoming changes) it has dependencies on optional libraries.

Rainer Orth 2feb72bcd5 [cmake] Don't pass -z discard-unused to Illumos ld
I'm currently working to port `libc++` to Solaris.  There exists a slightly
bitrotten port already, which was done on Illumos, an OpenSolaris
derivative.  In order not to break that port with my work, I need to test
the result on both Solaris and Illumos.  While doing so, it turned out that
Illumos `ld` doesn't support the `-z discard-sections=unused` option
currently used on SunOS unconditionally.

While there exists a patch
<https://github.com/OpenIndiana/oi-userland/blob/oi/hipster/components/developer/clang-90/patches/02-cmake_modules_AddLLVM.cmake.patch>
for LLVM 9.0 in the OpenIndiana repository, it apparently hasn't been
submitted upstream and is completely wrong: it replaces
`-z discard-sections=unused` with `-z ignore`.  In terms of the equivalent
`gld` options, this means replacing `--gc-sections` with `--as-needed`.

This patch instead tests if the linker actually supports the option before
using it.

Tested on `amd64-pc-solaris2.11` (all of Solaris 11.4, 11.3 and OpenIndiana
2020.04).

Nico Weber 5229dd1366 [build] Add LLVM_LOCAL_RPATH which can set an rpath on just unit test binaries
After D80096, bots that build clang for distribution and that can't use
system gcc / libstdc++ need to pass a working rpath so that unit test
binaries can run. The method suggested in GettingStarted.rst works fine
for local development, but it results in an absolute local rpath ending
up even in distributed binaries like clang, which is both ugly and
unnecessary.

Add an explicit toggle that can be used to add an rpath only for the
non-distributed binaries that need it.

Stephen Neuendorffer 085234bedc [cmake] Update creation of object library dependencies for LINK_LIBS PUBLIC
We need to avoid declaring dependencies on strings which are valid
LINK_LIBS and not valid targets.  Previously, we used if(TARGET) to
check this condition.  However, if(TARGET) checks whether a target has
been created (in the cmake subdirectory traversal order) and not
whether it *will* be created.  This results in annoying directory
ordering problems.

This patch changes the check to more explicitly eliminate problematic
libraries (namely -lpthread) using a REGEX.

 * Not having nm sort the list of symbols or we may run in to memory
   issues on debug builds, as nm calls a 32-bit sort.
 * Defaulting to having LLVM_EXPORT_SYMBOLS_FOR_PLUGINS on for AIX
 * CMake versions prior to 3.16 set the -brtl linker flag globally on
   AIX. Clear it out early on so we don't run into failures. We will set
   it as needed.

Stephen Neuendorffer 8303b1f46a [cmake] Ensure that LINK_LIBS are dependencies for object library targets
In MLIR, it is common for automatically generated headers to be included
in many places.  To avoid tracking these dependencies explicitly in
cmake, they are treated as part of a library which 'owns' the generated
header.  Users of the generated header link against the owning library.
However, object libraries don't actually 'link', so this dependence gets
lost.  This patch adds an explicit dependence for these generated headers
when creating object library targets to ensure that generated headers
are appropriately generated

This reverts commit bc3f54de18.

The patch breaks in the following two scenarios:

1. When manually passing an absolute path to llvm-lit with a lower-case

2. When the PWD has a lower-case drive letter, like after running
   `cd c:\` with a lower-case "c:" (cmd's default is upper-case, but
   it takes case-ness from what's passed to `cd` apparently).

Nico Weber bc3f54de18 [lit] Keep original cfg file case around.
There's been some back and forth if the cfg paths in the

it allows using all-lower spelling in cmd on Windows, the
argument against that doing so is lossy.

Before the relative-paths-in-generated-lit.site.cfg.py work,
there was no downside to calling normcase(), but with it
we need a hack to recover the original case.

This time, normcase() the hashtable key, but store the original
cased key in addition to the value. This fixes both cons, at the
cost of a few bytes more memory.

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.

way, a standalone build of clang can load this cmake file and get all the
configured standalone extensions.

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

This patch renames it to LLVM_SUPPORT_PLUGINS to convey the intended usage, which will allow subsequent patches to add behavior to support that in different ways without confusion about whether it will do on, for example, non-gnu platforms.

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.
