Initial, very rough cut at a new CMake build system for compiler-rt. Some high-level notes: 1) An explicit goal is to support building compiler-rt as a subproject build, checked out into the projects/compiler-rt directory. There are many other possible ways of building the code here, but this is optimized for development on LLVM/Clang/compiler-rt, and incremental trial and testing of the toolchain. 2) The current support is targeted at Linux. I would love to see this generalized to other platforms, but for the sake of simplicity in testing, I'm focusing here first. Much of this patch was paired with Manuel, and I credit him with the majority of the work here. Some important caveats that I'll be working on in subsequent patches: 1) This uses the host compiler rather than using the just-built-clang. 2) Currently only x86 is supported. 3) Currently, none of the tests are built or run. 4) Uses CMake's builtin globbing which doesn't update correctly. 5) This is still turned off from LLVM's CMake build until these issues are addressed llvm-svn: 154060

# CMake build for CompilerRT.

# An important constraint of the build is that it only produces libraries
# based on the ability of the host toolchain to target various platforms.
[CMake] Bump CMake minimum version to 3.13.4 This upgrade should be friction-less because we've already been ensuring that CMake >= 3.13.4 is used.

cmake_minimum_required(VERSION 3.13.4)
Call cmake_minimum_required at the top of CMakeLists.txt Summary: Since r298413, the NEW behavior of the CMake policy CMP0056 is followed. However, it is only effective after the call to cmake_minimum_required. This causes CMAKE_EXE_LINKER_FLAGS etc. to be unused when CMake tries to check compilers for languages specified in the 'project' declaration. Set cmake_minimum_required(VERSION) at the top of the file and ahead of the project declaration.

if (CMAKE_SOURCE_DIR STREQUAL CMAKE_CURRENT_SOURCE_DIR OR COMPILER_RT_STANDALONE_BUILD)
Let cmake infer source file language by the file extension. This applies default compiler flags to .S files, in particular removing the "-pedantic" option, which is desirable because there is nothing to reasonably warn about; and the only thing that gcc warns about is that you allegedly can't correctly invoke GLUE2 in lib/builtins/assembly.h on platforms for which USER_LABEL_PREFIX is the empty string. In the gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=33305 that added the warning, a commenter notes that giving a macro of zero characters to another macro is not precisely the same as failing to supply an argument, and "there is a widespread belief in C++ community that such usage is valid". Unfortunately the only way to silence the warning is to avoid -pedantic. Differential Revision: http://reviews.llvm.org/D10713 llvm-svn: 243446

[sanitizers] Sanitizer tests CMake clean up: try #2 This patch addresses two issues: Most of the time, hacks with `if/else` in order to get support for multi-configuration builds are superfluous.

The `if/else` hacks for the library name generation should also not be done, as CMake has `TARGET_FILE` generator expression precisely for this purpose, as it expands to the exact filename of the resulting target.

Reland "[compiler-rt] Simple crtbegin.o and crtend.o implementation" Clang relies on existence of certain symbols that are normally provided by crtbegin.o/crtend.o.

Fix include guard and properly order __deregister_frame_info. Summary: This patch fixes two problems with the crtbegin.c as written: 1. In do_init, register_frame_info is not guarded by a #define, but in do_fini, deregister_frame_info is guarded by #ifndef CRT_HAS_INITFINI_ARRAY. Thus when CRT_HAS_INITFINI_ARRAY is not defined, frames are registered but then never deregistered. The frame registry mechanism builds a linked-list from the .so's static variable do_init.object, and when the .so is unloaded, this memory becomes invalid and should be deregistered. Further, libgcc's crtbegin treats the frame registry as independent from the initfini array mechanism. This patch fixes this by adding a new #define, "EH_USE_FRAME_INFO_REGISTRY", which is set by the cmake option COMPILER_RT_CRT_USE_EH_FRAME_REGISTRY Currently, do_init calls register_frame_info, and then calls the binary's constructors. This allows constructors to safely use libunwind. However, do_fini calls deregister_frame_info and then calls the binary's destructors. This prevents destructors from safely using libunwind. This patch also switches that ordering, so that destructors can safely use libunwind. As it happens, this is a fairly common scenario for thread sanitizer.

[compiler-rt][XRay] re-submitting r276117, with fixes for build breakage due to extraneous and missing dependencies and attempts to build on unsupported OSes Summary: This is a fixed-up version of D21612, to address failure identified post-commit. Original commit description: This patch implements the initialisation and patching routines for the XRay runtime, along with the necessary trampolines for function entry/exit handling. For now we only define the basic hooks for allowing an implementation to define a handler that gets run on function entry/exit. We expose a minimal API for controlling the behaviour of the runtime (patching, cleanup, and setting the handler to invoke when instrumenting).

This patch adds the compiler-rt runtime support for the memory profiling. Note that much of this support was cloned from asan (and then greatly simplified and renamed). For example the interactions with the sanitizer_common allocators, error handling, interception, etc. The bulk of the memory profiling specific code can be found in the MemInfoBlock, MemInfoBlockCache, and related classes defined and used in memprof_allocator.cpp. For now, the memory profile is dumped to text (stderr by default, but honors the sanitizer_common log_path flag). It is dumped in either a default verbose format, or an optional terse format. This patch also adds a set of tests for the core functionality. Differential Revision: https://reviews.llvm.org/D87120

[XRay][compiler-rt] Allow for building the XRay runtime without PREINIT initialization. Summary: Define a build-time configuration option for the XRay runtime to determine whether the archive will add an entry to the `.preinit_array` section of the binary. We also allow for initializing the XRay data structures with an explicit call to __xray_init(). This allows us to give users the capability to initialize the XRay data structures on demand. This can allow us to start porting XRay to platforms where `.preinit_array` isn't a supported section. It also allows us to limit the effects of XRay in the initialization sequence for applications that are sensitive to this kind of interference (i.e. large binaries) or those that want to package XRay control in libraries. Future changes should allow us to build two different library archives for the XRay runtime, and allow clang users to determine which version to link.

[hwasan] Add a (almost) no-interceptor mode. Summary: The idea behind this change is to allow sanitization of libc. We are prototyping on Bionic, but the tool interface will be general enough (or at least generalizable) to support any other libc. When libc depends on libclang_rt.hwasan, the latter can not interpose libc functions. In fact, majority of interceptors become unnecessary when libc code is instrumented. This change gets rid of most hwasan interceptors and provides interface for libc to notify hwasan about thread creation and destruction events. Some interceptors (pthread_create) are kept under #ifdef to enable testing with uninstrumented libc. They are expressed in terms of the new libc interface. The new cmake switch, COMPILER_RT_HWASAN_WITH_INTERCEPTORS, ON by default, builds testing version of the library with the aforementioned pthread_create interceptor. With the OFF setting, the library becomes more of a libc plugin.

[CMake] Add the way to run tests in standalone build. 1) Depend on llvm-config (configured in LLVM_CONFIG_PATH) to get necessary LLVM source/binary directories. 2) Add basic support for running lit tests (check-xsan commands). For now this "support" is far from what we want: * unit tests are not built currently. * lit tests use Clang/compiler-rt from LLVM build directory, not the host compiler or just-built compiler-rt libraries. We should make a choice on the way we intend ti run compiler-rt lit testsuite: a) use either Clang from LLVM build tree, or the host compiler. b) use either just-built runtimes, or the runtimes shipped with the host compiler. Using just-built runtimes is tricky - we have to know where to put them, so that Clang/GCC driver would pick them up (and not overwrite the existing runtimes). Using a host compiler instead of Clang from LLVM build tree will give us a chance to run lit tests under GCC (which already has support for several sanitizers). That is, I tend to make the following choice: if we're in a standalone compiler-rt build, use host compiler with its set of runtime libraries to run lit tests. This will effectively decouple "make compiler-rt" and "make check-compiler-rt" in a standalone build - the latter wouldn't invoke the former. Note that if we decide to fix LLVM/Clang/compiler-rt build system so that it would configure/build compiler-rt with just-built Clang (as we do in Makefile-based build), this will not be a problem - we can add a dependency to ensure that clang/compiler-rt are rebuilt before running compiler-rt tests. llvm-svn: 201656

[CMake] Add the way to run tests in standalone build. 1) Depend on llvm-config (configured in LLVM_CONFIG_PATH) to get necessary LLVM source/binary directories. 2) Add basic support for running lit tests (check-xsan commands). For now this "support" is far from what we want: * unit tests are not built currently. * lit tests use Clang/compiler-rt from LLVM build directory, not the host compiler or just-built compiler-rt libraries. We should make a choice on the way we intend ti run compiler-rt lit testsuite: a) use either Clang from LLVM build tree, or the host compiler. b) use either just-built runtimes, or the runtimes shipped with the host compiler. Using just-built runtimes is tricky - we have to know where to put them, so that Clang/GCC driver would pick them up (and not overwrite the existing runtimes). Using a host compiler instead of Clang from LLVM build tree will give us a chance to run lit tests under GCC (which already has support for several sanitizers). That is, I tend to make the following choice: if we're in a standalone compiler-rt build, use host compiler with its set of runtime libraries to run lit tests. This will effectively decouple "make compiler-rt" and "make check-compiler-rt" in a standalone build - the latter wouldn't invoke the former. Note that if we decide to fix LLVM/Clang/compiler-rt build system so that it would configure/build compiler-rt with just-built Clang (as we do in Makefile-based build), this will not be a problem - we can add a dependency to ensure that clang/compiler-rt are rebuilt before running compiler-rt tests. llvm-svn: 201656

Resubmit "[lit] Force site configs to run before source-tree configs" This is a resubmission of r313270. It broke standalone builds of compiler-rt because we were not correctly generating the llvm-lit script in the standalone build directory. The fixes incorporated here attempt to find llvm/utils/llvm-lit from the source tree returned by llvm-config. If present, it will generate llvm-lit into the output directory. Regardless, the user can specify -DLLVM_EXTERNAL_LIT to point to a specific lit.py on their file system. This supports the use case of someone installing lit via a package manager. If it cannot find a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or invalid, then we print a warning that tests will not be able to run.

[sanitizer] Disable fast_unwind_on_malloc as default for arm-linux-gnu ARM thumb/thumb2 frame pointer is inconsistent on GCC and Clang [1] and fast-unwider is also unreliable when mixing arm and thumb code [2]. The fast unwinder on ARM tries to probe and compare the frame-pointer at different stack layout positions and it works reliable only on systems where all the libraries were built in arm mode (either with gcc or clang) or with clang in thmb mode (which uses the same stack frame pointer layout in arm and thumb). However when mixing objects built with different abi modes the fast unwinder is still problematic as shown by the failures on the AddressSanitizer.ThreadStackReuseTest. For these failures, the malloc is called by the loader itself and since it has been built with a thum enabled gcc, the stack frame is not correctly obtained and the suppression rule is not applied (resulting in a leak warning). The check for fast-unwinder-works is also changed: instead of checking f it is explicit enabled in the compiler flags, it now checks if compiler defined thumb pre-processor. This should fix BZ#44158.

ubsan: Unbreak ubsan_cxx runtime library on Windows. This was originally broken by r258744 which introduced a weak reference from ubsan to ubsan_cxx.

[CMake] Enable -qfuncsect when building with IBM XL Summary: The IBM XL compiler uses `-qfuncsect` for `-ffunction-sections`. The comment about sanitizers and `-f[no-]function-sections` is corrected also, as it is pertinent to this patch. The sanitizer-related use of `-fno-function-sections` is associated with powerpc64le, a target for which there is an IBM XL compiler, so that use is updated in this patch to apply `-qnofuncsect` in case a build using the XL compiler is viable on that platform. This patch has been verified with the XL compiler on AIX only.

[compiler-rt][SystemZ] Work around ASAN failures via -fno-partial-inlining Since updating the SystemZ LLVM build bot system to Ubuntu 18.04, all bots are red due to two ASAN failures. It turns out these are triggered due to building the ASAN support libraries, in particular the interceptor routines using GCC 7. Specifically, at least on our platform, this compiler decides to "partially inline" some of those interceptors, creating intermediate stub routines like "__interceptor_recvfrom.part.321". These will show up in the backtraces at interception points, causing testsuite failures. As a workaround to get the build bots green again, this patch adds the -fno-partial-inlining command line option when building the common sanitizer support libraries on s390x, if that option is supported by the compiler. llvm-svn: 363679

# The following is a workaround for s390x. This avoids creation of "partial

The fixes incorporated here attempt to find llvm/utils/llvm-lit from the source tree returned by llvm-config. If present, it will generate llvm-lit into the output directory. Regardless, the user can specify -DLLVM_EXTERNAL_LIT to point to a specific lit.py on their file system. This supports the use case of someone installing lit via a package manager. If it cannot find a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or invalid, then we print a warning that tests will not be able to run.

Initial, very rough cut at a new CMake build system for compiler-rt. Some high-level notes: 1) An explicit goal is to support building compiler-rt as a subproject build, checked out into the projects/compiler-rt directory. There are many other possible ways of building the code here, but this is optimized for development on LLVM/Clang/compiler-rt, and incremental trial and testing of the toolchain. 2) The current support is targeted at Linux. I would love to see this generalized to other platforms, but for the sake of simplicity in testing, I'm focusing here first. Much of this patch was paired with Manuel, and I credit him with the majority of the work here. Some important caveats that I'll be working on in subsequent patches: 1) This uses the host compiler rather than using the just-built-clang. 2) Currently only x86 is supported. 3) Currently, none of the tests are built or run. 4) Uses CMake's builtin globbing which doesn't update correctly. 5) This is still turned off from LLVM's CMake build until these issues are addressed llvm-svn: 154060

[compiler-rt] Don't build llvm-lit in RUNTIMES-BUILD With runtimes-build, we lost map config for llvm-lit, so we can NOT run lit from source dir anymore. All the subdir target like: ninja check-llvm-codegen-powerpc will fail too. We will get some cfg error like: File "../lvm-project/llvm/test/lit.cfg.py", line 21, in <module> config.test_format = lit.formats.ShTest(not llvm_config.use_lit_shell) AttributeError: 'NoneType' object has no attribute 'use_lit_shell' This is reset of map config in llvm-lit rebuild. We already have llvm-lit in runtimes-build, so don't build it. Reviewed By: phosek Differential Revision: https://reviews.llvm.org/D87002

Resubmit "[lit] Force site configs to run before source-tree configs" This is a resubmission of r313270. It broke standalone builds of compiler-rt because we were not correctly generating the llvm-lit script in the standalone build directory. The fixes incorporated here attempt to find llvm/utils/llvm-lit from the source tree returned by llvm-config. If present, it will generate llvm-lit into the output directory. Regardless, the user can specify -DLLVM_EXTERNAL_LIT to point to a specific lit.py on their file system. This supports the use case of someone installing lit via a package manager. If it cannot find a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or invalid, then we print a warning that tests will not be able to run.

Reland "Make llvm_source_root in llvm-lit relative too." This reverts commit 3185881d69022e03b300e189838b0599ed417be5 and adds a missing "include(AddLLVM)" (similar lines already exist elsewhere in compiler-rt).

Initial, very rough cut at a new CMake build system for compiler-rt. Some high-level notes: 1) An explicit goal is to support building compiler-rt as a subproject build, checked out into the projects/compiler-rt directory. There are many other possible ways of building the code here, but this is optimized for development on LLVM/Clang/compiler-rt, and incremental trial and testing of the toolchain. 2) The current support is targeted at Linux. I would love to see this generalized to other platforms, but for the sake of simplicity in testing, I'm focusing here first. Much of this patch was paired with Manuel, and I credit him with the majority of the work here. Some important caveats that I'll be working on in subsequent patches: 1) This uses the host compiler rather than using the just-built-clang. 2) Currently only x86 is supported. 3) Currently, none of the tests are built or run. 4) Uses CMake's builtin globbing which doesn't update correctly. 5) This is still turned off from LLVM's CMake build until these issues are addressed llvm-svn: 154060

Add GWP-ASan fuzz target to compiler-rt/tools. Summary: @eugenis to approve addition of //compiler-rt/tools. @pree-jackie please confirm that this WFY. D66494 introduced the GWP-ASan stack_trace_compressor_fuzzer. Building fuzz targets in compiler-rt is a new affair, and has some challenges: - If the host compiler doesn't have compiler-rt, the -fsanitize=fuzzer may not be able to link against `libclang_rt.fuzzer*`. - Things in compiler-rt generally aren't built when you want to build with sanitizers using `-DLLVM_USE_SANITIZER`. This tricky to work around, so we create the new tools directory so that we can build fuzz targets with sanitizers. This has the added bonus of fixing the problem above as well, as we can now just guard the fuzz target build to only be done with `-DLLVM_USE_SANITIZE_COVERAGE=On`.
