Sanjoy Das 8ce6499bdd [ADT][CMake][AutoConf] Fail-fast iterators for DenseMap
Summary:
This patch is an attempt at making `DenseMapIterator`s "fail-fast".
Fail-fast iterators that have been invalidated due to insertion into
the host `DenseMap` deterministically trip an assert (in debug mode)
on access, instead of non-deterministically hitting memory corruption
issues.

Enabling fail-fast iterators breaks the LLVM C++ ABI, so they are
predicated on `LLVM_ENABLE_ABI_BREAKING_CHECKS`.
`LLVM_ENABLE_ABI_BREAKING_CHECKS` by default flips with
`LLVM_ENABLE_ASSERTS`, but can be clamped to ON or OFF using the CMake /
autoconf build system.

Chris Bieneman 9ea37d9d04 Re-land: Generate targets for each lit suite.
Summary:
This change makes CMake scan for lit suites and generate a target for each lit test suite. The targets follow the format check-<project>-<suite path>.

For example:
check-llvm-unit - Runs the LLVM unit tests
check-llvm-codegen-arm - Runs the ARM codeine tests

Note: These targets are not generated during multi-configuration generators (i.e. Xcode and Visual Studio) because target clutter impacts UI usability.

* Also fixed a minor issue that Duncan pointed out to me I was passing the suite to lit twice

Chris Bieneman ca4f699cc2 Fixing dependencies for native tablegen.
The dependencies for cross-built tablegen were a bit confused. This fixes that. The following dependencies are now enforced:

(1) Tablegen tasks depend on the native tablegen
(2) Native tablegen depends on the cross-compiled tablegen

Although the native tablegen doesn't actually require the cross tablegen, having this dependency forces the native tablegen to rebuild whenever the cross tablegen changes.

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present, and therefore the target was out of date.

Kostya Serebryany be5e0ed919 [sanitizer/coverage] Add AFL-style coverage counters (search heuristic for fuzzing).
Introduce -mllvm -sanitizer-coverage-8bit-counters=1
which adds imprecise thread-unfriendly 8-bit coverage counters.

The run-time library maps these 8-bit counters to 8-bit bitsets in the same way
AFL (http://lcamtuf.coredump.cx/afl/technical_details.txt) does:
counter values are divided into 8 ranges and based on the counter
value one of the bits in the bitset is set.
The AFL ranges are used here: 1, 2, 3, 4-7, 8-15, 16-31, 32-127, 128+.

These counters provide a search heuristic for single-threaded
coverage-guided fuzzers, we do not expect them to be useful for other purposes.

Depending on the value of -fsanitize-coverage=[123] flag,
these counters will be added to the function entry blocks (=1),
every basic block (=2), or every edge (=3).

Use these counters as an optional search heuristic in the Fuzzer library.
Add a test where this heuristic is critical.

Zachary Turner aeedd65c64 Teach llvm_add_library() to find include dirs.
Since header files are not compilation units, CMake does not require
you to specify them in the CMakeLists.txt file.  As a result, unless a
header file is explicitly added, CMake won't know about it, and when
generating IDE-based projects, CMake won't put the header files into
the IDE project.  LLVM currently tries to deal with this in two ways:

  1) It looks for all .h files that are in the project directory, and
     adds those.
  2) llvm_add_library() understands the ADDITIONAL_HEADERS argument,
     which allows one to list an arbitrary list of headers.

This patch takes things one step further.  It adds the ability for
llvm_add_library() to take an ADDITIONAL_HEADER_DIRS argument, which
will specify a list of folders which CMake will glob for header files.
Furthermore, it will glob not only for .h files, but also for .inc
files.

Included in this CL is an update to one of the existing users of
ADDITIONAL_HEADERS to use this new argument instead, to serve as an
illustration of how this cleans up the CMake.

The big advantage of this new approach is that until now, there was no
way for the IDE projects to locate the header files that are in the
include tree.  In other words, if you are in, for example,
lib/DebugInfo/DWARF, the corresponding includes for this project will
be located under include/llvm/DebugInfo/DWARF.  Now, in the
CMakeLists.txt for lib/DebugInfo/DWARF, you can simply write:

  ADDITIONAL_HEADER_DIRS
  ../../include/llvm/DebugInfo/DWARF

as an argument to llvm_add_library(), and all header files will get
added to the IDE project.

This creates a situation where a .so might build on an ELF system, but the build

Chandler Carruth ab8df0b6c6 [cmake] Push LLVM_LIBDIR_SUFFIX through to the LLVMConfig.cmake file

Chandler Carruth a78e24e548 [cmake] Start making LLVM_LIBDIR_SUFFIX effective by adding it to
*numerous* places where it was missing in the CMake build. The primary
change here is that the suffix is now actually used for all of the lib
directories in the LLVM project's CMake. The various subprojects still
need similar treatment.

This is the first of a series of commits to try to make LLVM's cmake
effective in a multilib Linux installation. I don't think many people
are seriously using this variable so I'm hoping the fallout will be
minimal. A somewhat unfortunate consequence of the nature of these
commits is that until I land all of them, they will in part make the
brokenness of our multilib support more apparant. At the end, things
should actually work.

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/libLLVMMCParser.so lib/libLLVMMC.so lib/libLLVMObject.so

to

build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp

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.

warning when building with BUILD_SHARED_LIBS.

Reid Kleckner 19cb171ee1 Suppress MSVC's equivalent of -Wshadow warnings
IMO we need to clean up some of these, but the member variable one
(C4458) has false positives on static methods.  It is currently firing
on Twine, which has a static method like:
  struct Twine {
    uintptr_t LHS, RHS;
    static void staticMethod() {
      // warning C4458: declaration of 'LHS' hides class member
      uintptr_t LHS;
      ...
    }
  };

We should fix up clang's -Wshadow and clean it up, and then we can
re-enable some of these MSVC warnings.

Now it attempts to find llvm-symbolizer binary and communicates

function/file/line info entries. This should significantly improve
stack traces readability in Debug builds.

This feature only works on selected platforms (including Darwin
and Linux). If the symbolization fails for some reason, signal
handler will fallback to the original behavior.

When --enable_shared is passed the Makefile.rules does not set the
LLVMConfigLibs variable which cmake/modules/Makefile previously relied

This directory can be user provided (and configured), or it can be created during the build. During a build the native build directory will be configured and built to supply the tablegen tools used during the build.

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.

Alp Toker 696b4a089c Prospective -fsanitize=memory build fix following r212586
This -f group flag appears to influence linker flags, breaking the usual rules
and causing CMake's link invocation to fail during feature detection due to
missing link dependencies (msan_*).

Let's forcibly add it for now to get things the way they were before feature
detection started working.

Alp Toker 7099cd7549 CMake: make __DATE__, __TIME__ etc. macro usage an error
When LLVM_ENABLE_TIMESTAMPS has been disabled we can prevent the preprocessor
from embedding dates, times and file timestamps.

There are a few motivations for this:

  1) Validate the recent CMake feature detection bugfix from LLVM r212586 with
     a flag that's not actually available everywhere.

  2) Dogfood clang's new -Wdate-time warning from r210511 when bootstrapping.

  3) Encourage reproducible builds.

Alp Toker 0068397f34 CMake: fix compiler feature detection
add_flag_if_supported() and add_flag_or_print_warning() were effectively
no-ops, just returning the value of the first result (usually
'-fno-omit-frame-pointer') for all subsequent checks for different flags.

Due to the way CMake caches feature detection results, we need to provide
symbolic variable names which will persist the cached results. This commit
fixes feature detection using these two macros.

The feature checks now run and get stored correctly, and the correct output can
be observed in configure logs:

  -- Performing Test C_SUPPORTS_FPIC
  -- Performing Test C_SUPPORTS_FPIC - Success
  -- Performing Test CXX_SUPPORTS_FPIC
  -- Performing Test CXX_SUPPORTS_FPIC - Success

Reid Kleckner 3260478c10 cmake: Don't do anything for LLVM_ENABLE_ASSERTIONS=OFF
By default, CMake will set NDEBUG in Rel* builds and leave it off in
debug builds, so we shouldn't need to do anything ourselves.

Before this change, it was possible to a Debug build without assertions
(aka Debug-Asserts in the autoconf system) by configuring with
-DLLVM_ENABLE_ASSERTIONS=OFF, but this configuration isn't very useful.
You can still get the same effect by explicitly adding -DNDEBUG to
CFLAGS.

Alp Toker 5627ee47f4 Remove clang-specific libxml2 check from CMake
clang's own CMake setup handles this as of r210308.

The CMAKE_CROSSCOMPILING special-case will no longer be hard-coded. This was
clearly site-specific to someone's local configuration and should be passed in
at configure time if needed with e.g. -DLIBXML2_LIBRARIES=... (the libxml2
target I tried here doesn't even support liblzma so it's *way* off).

Alp Toker 125be8465d GraphWriter: detect graph viewer programs at runtime
Replace the crufty build-time configure checks for program paths with
equivalent runtime logic.

This lets users install graphing tools as needed without having to reconfigure
and rebuild LLVM, while eliminating a long chain of inappropriate compile
dependencies that included GUI programs and the windowing system.

Additional features:

 * Support the OS X 'open' command to view graphs generated by any of the
   Graphviz utilities. This is an alternative to the Graphviz OS X UI which is
   no longer available on Mountain Lion.

 * Produce informative log output upon failure to indicate which programs can
   be installed to view graphs.

Ping me if this doesn't work for your particular environment.

Tim Northover 3b0846e8f7 AArch64/ARM64: move ARM64 into AArch64's place
This commit starts with a "git mv ARM64 AArch64" and continues out
from there, renaming the C++ classes, intrinsics, and other
target-local objects for consistency.

"ARM64" test directories are also moved, and tests that began their
life in ARM64 use an arm64 triple, those from AArch64 use an aarch64
triple. Both should be equivalent though.

This finishes the AArch64 merge, and everyone should feel free to
continue committing as normal now.

Reid Kleckner 9f5eb637cb Added Sphinx documentation generation to CMake build system.
The option LLVM_ENABLE_SPHINX option enables the "docs-llvm-html",
"docs-llvm-man" targets but does not build them by default. The
following CMake options have been added that control what targets are
made available

SPHINX_OUTPUT_HTML
SPHINX_OUTPUT_MAN

If LLVM_BUILD_DOCS is enabled then the enabled docs-llvm-* targets will
be built by default and if ``make install`` is run then docs-llvm-html
and docs-llvm-man will be installed (tested on Linux only).

The add_sphinx_target function is in its own file so it can be included
by other projects that use Sphinx for their documentation.
