NAKAMURA Takumi 04e2da526f [CMake] Make LLVM_EXTERNAL_*_SOURCE_DIR consistent against older buildsites.
If corresponding in-tree subdirectory exists, just ignore LLVM_EXTERNAL* stuff.
Otherwise, set LLVM_TOOL_*_BUILD ON/OFF properly according to LLVM_EXTERNAL_*.

This makes easier to walk among old revisions *without* deleteing CMakeCache.txt.

Before r242059, LLVM_EXTERNAL_* was working like;

  if(EXISTS ${*_SOURCE_DIR}/CMakeLists.txt)
    set(*_BUILD ON CACHE)
    if(*_BUILD is ON)
      add_subdirectory(*_SOURCE_DIR)
    endif()
  endif()

Reid Kleckner 7752db61cc Revert "[cmake] Add helper for finding potentially external projects"
This reverts commit r244633.

We aren't going to be able to use it because the compiler-rt build can
be built standalone without an LLVM source dir *or* an installed copy of
LLVM.

Chris Bieneman 19d42692e7 [CMake] Projects supported via LLVM_EXTERNAL_*_SOURCE_DIR need to be explicitly specified.
One part of my refactoring from r242705 is untenable due to how CMake caches variables. There is no way other than caching to allow variables to be set in one directory and globally readable, but we really don't want to cache the temporary value marking that a directory has already been included.

Andrew Wilkins 6c1bfa93f5 [cmake] pass GO_EXECUTABLE to llgo-go
Summary:
When calling llgo-go from the llvm_add_go_executable
cmake function, specify $GO_EXECUTABLE as the go
command to call. Without this, llgo-go searches $PATH
which may be inconsistent with $GO_EXECUTABLE.

Chris Bieneman 580d8159d5 [CMake] Cleanup tools/CMakeLists.txt to take advantage of the auto-registration that was already partially working.
Re-landing r242059 which re-landed r241621... I'm really bad at this.

Summary (r242059):
This change re-lands r241621, with an additional fix that was required to allow tool sources to live outside the llvm checkout. It also no longer renames LLVM_EXTERNAL_*_SOURCE_DIR. This change was reverted in r241663, because it renamed several variables of the format LLVM_EXTERNAL_*_* to LLVM_TOOL_*_*.

Summary (r241621):
The tools CMakeLists file already had implicit tool registration, but there were a few things off about it that needed to be altered to make it work. This change addresses all that. The changes in this patch are:

* factored out canonicalizing tool names from paths to CMake variables * removed the LLVM_IMPLICIT_PROJECT_IGNORE mechanism in favor of LLVM_EXTERNAL_${nameUPPER}_BUILD which I renamed to LLVM_TOOL_${nameUPPER}_BUILD because it applies to internal and external tools
* removed ignore_llvm_tool_subdirectory() in favor of just setting LLVM_TOOL_${nameUPPER}_BUILD to Off
* Added create_llvm_tool_options() to resolve a bug in add_llvm_external_project() - the old LLVM_EXTERNAL_${nameUPPER}_BUILD would not work on a clean CMake directory because the option could be created after it was set in code.
* Removed all but the minimum required calls to add_llvm_external_project from tools/CMakeLists.txt

Chris Bieneman 3da1b6e260 [CMake] We shouldn't be storing values in the cache unless they actually need CMake cache behavior.
add_llvm_external_project puts LLVM_EXTERNAL_${nameUPPER}_SOURCE_DIR into the cache even if it is just the in-tree default path. This causes all sorts of oddness, and makes it so that I can't change the behavior of this variable.

This patch never puts LLVM_EXTERNAL_${nameUPPER}_SOURCE_DIR into the cache. It will only end up in the cache if it is specified on the command line, which is the correct behavior.

There is also a temporary change to remove non-default values from the cache if they are already present. This should have the impact of cleaning out unncecissary values from the caches on the buildbots and people's local build directories. This part of the change is marked with a TODO and can be removed in a few days.

Dan Liew 80189d2d15 Fix bug #23967. The gtest and gtest_main targets were exported into the
CMake files and should not be by both build systems and also the targets
were also installed by the CMake build system which they should not be.

The problem was that

- the CMake build of LLVM installs and exports the gtest library
targets. We should not being doing this, these are not part of LLVM.

- the Autoconf/Makefile build of LLVM still had gtest libraries in the
installed LLVMConfig.cmake.

These problems would cause problems for an external project because when
calling llvm_map_components_to_libnames(XXX all) ${XXX} would to contain
LLVM's internal gtest libraries.

Chris Bieneman 8427169642 Fixing a mis-use of the CMake install command.
The CMake install command is defined as:

install(TARGETS targets... [EXPORT <export-name>]
        [[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
          PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
         [DESTINATION <dir>]
         [INCLUDES DESTINATION [<dir> ...]]
         [PERMISSIONS permissions...]

         [COMPONENT <component>]
         [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
        ] [...])

This means it can only take one parameter from the set of RUNTIME, LIBRARY, or ARCHIVE. If you set more than one of these it seems to gobble up the extra arguments and ignore the COMPONENT argument.

This adds a check to only set LIBRARY or ARCHIVE based on whether or not the library being built is shared.

Reid Kleckner 3e8c445c96 CMake: Disable ENABLE_EXPORTS for executables with MSVC
The MSVC linker won't produce a .lib file for an executable that doesn't
export anything, and LLVM doesn't maintain dllexport annotations or .def
files listing all C++ symbols. It also doesn't support exporting all
symbols, like binutils ld.

CMake 3.2 changed the Ninja generator to list both the .exe and .lib
files as outputs of executable build targets. Ninja would always re-link
executables with ENABLE_EXPORTS because the .lib output file was not
present, and therefore the target was out of date.

Chandler Carruth cab512d629 [go] Teach the go cmake build functions to funnel the include directories down into the cgo-setup variables of llvm-go.
Summary:
This in turn allows us to use #includes with cgo that rely on CMake
provided include directories which is particularly useful for handling
generated headers that aren't reasonable to put in an "installable"
location.

Rafael Espindola f9dcf9029b Pass PRIVATE to target_link_libraries if using shared libraries.
A shared library (unlike a .a), has its dependencies recorded in the library and
we can pass PRIVATE to target_link_libraries.

This patch then removes some bogus dependencies when using
BUILD_SHARED_LIBS=ON. For example, we go from

build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMBitReader.so
lib/libLLVMTransformUtils.so lib/libLLVMInstCombine.so
lib/libLLVMScalarOpts.so lib/libLLVMipa.so lib/libLLVMAnalysis.so
lib/libLLVMMCParser.so lib/libLLVMMC.so lib/libLLVMObject.so
lib/libLLVMTarget.so lib/libLLVMProfileData.so

to

build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMTransformUtils.so
lib/libLLVMScalarOpts.so lib/libLLVMAnalysis.so lib/libLLVMMC.so
lib/libLLVMTarget.so

In fact, build.ninja goes from 5231028 bytes to 4896759 bytes.

With this, old verisons of bfd ld (2.24 is OK, 2.23 warns) will print a bogus
warning when building with BUILD_SHARED_LIBS.

  Hello: bin/opt: symbol lookup error: lib/LLVMHello.so: undefined symbol: _ZN4llvm11raw_ostream13write_escapedENS_9StringRefEb

NAKAMURA Takumi 6a931f507a [CMake][Win32.DLL] Let llvm_add_library(SHARED) link dependent libraries as PRIVATE.
For example, c-index-test.exe requires just libclang.dll (its import library).
When libraries in libclang were not PRIVATE but PUBLIC, c-index-test required libraries transitive by libclang.

Note, on mingw with BUILD_SHARED_LIBS, library dependencies would become more strict.
In principle, required libraries should be "required in its source file".

This will help to detect missing dependencies.

NAKAMURA Takumi 955d27a4ce [CMake] Use target_link_libraries(INTERFACE|PRIVATE) on CMake-2.8.12 to increase opportunity for parallel build.
target_link_libraries(INTERFACE) doesn't bring inter-target dependencies in add_library,
although final targets have dependencies to whole dependent libraries.
It makes most libraries can be built in parallel.

target_link_libraries(PRIVATE) is used to shaared library.
Each dependent library is linked to the target.so, and its user will not see its grandchildren.
For example,

  - libclang.so has sufficient libclang*.a(s).
  - c-index-test requires just only libclang.so.

FIXME: lld is tweaked minimally. Adding INTERFACE in each library would be better thing.
