* [CMake] Tidy up the organisation of compiler-rt when configured as a standaloneDan Liew2018-06-271-0/+2
| | | | | | | | | | | | | | | | | | | build with an IDE (e.g. Xcode) as the generator. Previously the global `USE_FOLDERS` property wasn't set in standalone builds leading to existing settings of FOLDER not being respected. In addition to this there were several targets that appeared at the top level that were not interesting and clustered up the view. These have been changed to be displayed in "Compiler-RT Misc". Now when an Xcode project is generated from a standalone compiler-rt build the project navigator is much less cluttered. The interesting libraries should appear in "Compiler-RT Libraries" in the IDE.

* [sanitizer] Move cxx-abi library earlier in link flags.Evgeniy Stepanov2017-10-041-3/+1
| | | | | | | | | | | | | | | | | | | | Summary: This change moves cxx-abi library in asan/ubsan/dd link command line ahead of other libraries, such as pthread/rt/dl/c/gcc. Given that cxx-abi may be the full libstdc++/libc++, it makes sense for it to be ahead of libc and libgcc, at least. The real motivation is Android, where in the arm32 NDK toolchain libstdc++.a is actually a linker script that tries to sneak LLVM's libunwind ahead of libgcc's. Wrong library order breaks unwinding.

* Refactor MemoryMappingLayout::Next to use a single struct instead of output ↵Francis Ricci2017-07-111-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | parameters. NFC. Summary: This is the first in a series of patches to refactor sanitizer_procmaps to allow MachO section information to be exposed on darwin. In addition, grouping all segment information in a single struct is cleaner than passing it through a large set of output parameters, and avoids the need for annotations of NULL parameters for unneeded information. The filename string is optional and must be managed and supplied by the calling function. This is to allow the MemoryMappedSegment struct to be stored on the stack without causing overly large stack sizes.

* [tsan] Switch to InternalAlloc everywhere __libc_malloc is currently usedKuba Brecka2016-06-061-3/+0
| | | | | | | | | | | | This patch replaces all uses of __libc_malloc and friends with the internal allocator. It seems that the only reason why we have calls to __libc_malloc in the first place was the lack of the internal allocator at the time. Using the internal allocator will also make sure that the system allocator is never used (this is the same behavior as ASan), and we don’t have to worry about working with unknown pointers coming from the system allocator.

| | | | | | | | | | | | | | | | into a single function Summary: This refactoring moves much of the Apple-specific behavior into a function in AddCompilerRT. The next cleanup patch will remove more of the if(APPLE) checks in the outlying CMakeLists. This patch adds a bunch of new functionality to add_compiler_rt_runtime so that the target names don't need to be reconstructed outside the call. It also updates some of the call sites to exercise the new functionality, but does not update all uses fully. Subsequent patches will further update call sites and move to using the new features.

* CMake: Stop using LLVM's custom parse_arguments. NFCFilipe Cabecinhas2015-06-191-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: Use CMake's cmake_parse_arguments() instead. It's called in a slightly different way, but supports all our use cases. It's in CMake 2.8.8, which is our minimum supported version. CMake 3.0 doc (roughly the same. No direct link to 2.8.8 doc): http://www.cmake.org/cmake/help/v3.0/module/CMakeParseArguments.html?highlight=cmake_parse_arguments Since I was already changing these calls, I changed ARCH and LIB into ARCHS and LIBS to make it more clear that they're lists of arguments.

The goal of this is to try to push platform handling as low in the utility functions as possible.
