Add a test harness Mostly cargo-culted from libcxxabi, since the unwinder was forked from there in the first place. There may still be cruft that's only applicable to libcxxabi, but that can be addressed in-tree. https://reviews.llvm.org/D35038 llvm-svn: 307266

[libunwind] Support stack unwind in CET environment Control-flow Enforcement Technology (CET), published by Intel, introduces shadow stack feature aiming to ensure a return from a function is directed to where the function was called. In a CET enabled system, each function call will push return address into normal stack and shadow stack, when the function returns, the address stored in shadow stack will be popped and compared with the return address, program will fail if the 2 addresses don't match. In exception handling, the control flow may skip some stack frames and we must adjust shadow stack to avoid violating CET restriction. In order to achieve this, we count the number of stack frames skipped and adjust shadow stack by this number before jumping to landing pad.

Reland "Enable `-funwind-tables` flag when building libunwind" Summary: Relands https://reviews.llvm.org/D70815. The original commit set `CMAKE_TRY_COMPILE_TARGET_TYPE` to `STATIC_LIBRARY` globally in libunwind/CMakeLists.txt, which effectively disabled the linking step in CMake checks. This broke some builds (see 938c70b86c7d2165f8c28d5700e9c1ac1263307e). Here we set CMAKE_TRY_COMPILE_TARGET_TYPE to STATIC_LIBRARY only when checking for presence of the `-funwind-tables` flag, and then set it back to the original value so it doesn't affect other checks.

[CMake] Update lit test configuration There are several changes: - Don't stringify Pythonized bools (that's why we're Pythonizing them) - Support specifying target and sysroot via CMake variables - Use consistent spelling for --target, --sysroot, --gcc-toolchain llvm-svn: 353137

[libc++] Allow specifying arbitrary custom executors with the new format The integration between CMake and executor selection in the new format wasn't very flexible -- only the default executor and SSH executors were supported. This patch makes it possible to specify arbitrary executors with the new format. With the new testing format, a custom executor is just a script that gets called with a command-line to execute, and some arguments like --env, --codesign_identity and --execdir. As such, the default executor is just run.py. Remote execution with the SSH executor can be achived by specifying LIBCXX_EXECUTOR="<path-to-ssh.py> --host <host>". Similarly, arbitrary scripts can be provided.

[runtimes] Remove FOO_TARGET_TRIPLE, FOO_SYSROOT and FOO_GCC_TOOLCHAIN Instead, folks can use the equivalent variables provided by CMake to set those. This removal aims to reduce complexity and potential for confusion when setting the target triple for building the runtimes, and make it correct when `CMAKE_OSX_ARCHITECTURES` is used (right now both `-arch` and `--target=` will end up being passed, which is downright incorrect).

[runtimes] Serialize all Lit params instead of passing them to add_lit_testsuite add_lit_testsuite() takes Lit parameters passed to it and adds them to the parameters used globally when running all test suites. That means that a target like `check-all`, which ends up calling Lit on the whole monorepo, will see the test parameters for all the individual project's test suites. So, for example, it would see `--param std=c++03` (from libc++abi), and `--param std=c++03` (from libc++), and `--param whatever` (from another project being tested at the same time). While always unclean, that works when the parameters all agree. However, if the parameters share the same name but have different values, only one of those two values will be used and it will be incredibly confusing to understand why one of the test suites is being run with the incorrect parameter value. For that reason, this commit moves away from using add_lit_testsuite()'s PARAM functionality, and serializes the parameter values for the runtimes in the generated config.py file instead, which is local to the specific test suite.
