configs	[libc++] Allow testing Apple's system library as it is installed (#99086) In order to test libc++ under the "Apple System Library" configuration, we need to run the tests using DYLD_LIBRARY_PATH. This is required because libc++ gets an install_name of /usr/lib when built as a system library, which means that we must override the copy of libc++ used by the whole process. This effectively reverts 2cf2f1b, which was the wrong solution for the problem I was having. Of course, this assumes that the just-built libc++ is sufficient to replace the system library, which is not actually the case out-of-the-box. Indeed, the system library contains a few symbols that are not provided by the upstream library, leading to undefined symbols when replacing the system library by the just-built one. To solve this problem, we separately build shims that provide those missing symbols and we manually link against them when we build executables in the tests. While this is somewhat brittle, it provides a localized and unintrusive way to allow testing the Apple system configuration in an upstream environment, which has been a frequent request.	2 年前
libcxx	[libc++] Use a different smart ptr type alias (#102089) The _SP type is used by some C libraries and this alias could conflict with it. (cherry picked from commit 7951673d408ee64744d0b924a49db78e8243d876)	1 年前
std	[libc++] Adjust the version of __cpp_lib_ranges in C++20 mode This is a (very partial) cherry-pick of #101715 to fix this oversight in the LLVM 19 release.	1 年前
support	[libc++][math] Fix undue overflowing of std::hypot(x,y,z) (#100820) This is in relation to mr #93350. It was merged to main, but reverted because of failing sanitizer builds on PowerPC. The fix includes replacing the hard-coded threshold constants (e.g. __overflow_threshold) for different floating-point sizes by a general computation using std::ldexp. Thus, it should now work for all architectures. This has the drawback of not being constexpr anymore as std::ldexp is not implemented as constexpr (even though the standard mandates it for C++23). Closes #92782 (cherry picked from commit 72825fde03aab3ce9eba2635b872144d1fb6b6b2)	1 年前
tools	[libc++] Disable the clang-tidy checks to get CI back (#109989) The CI has been a complete mess for the past week, and the only thing preventing it from being back is the Clang tidy checks. Disable them (as a total hack) to get CI back. (cherry picked from commit 78c6506543dee13c9335edc5c85bc73c4853fbd7)	1 年前
.clang-format	[libc++] Improves clang-format settings. Add a new test based .clang-format file which inherits from the generic one. This moves some test specific formatting rules to the test directory. The main benefit is that headers are sorted, which makes it more likely to catch these errors before creating a review instead of spotting the error in the CI clang-tidy step.

.clang-tidy	[libc++] Update clang-tidy configuration for the tests This is to avoid clang-tidy complaining all over the tests that the naming is wrong.	2 年前
CMakeLists.txt	[libc++] Remove Windows-specific configuration from libcxx/test/CMakeLists.txt (#96330) This is essentially a revert of 9853e9b which tried removing duplication in the Windows config files by moving it to the CMake. However, we want to decouple the CMake and the test suite as much as possible, so encoding additional (non-official) Lit parameters in the CMake only as a code reuse mechanism is not an approach we want to take.	2 年前
