This isless flexible for users, however it will actually work as intendedand it will allow us, in the future, to add various kinds of checksthat do not assume the same ABI as the normal library. Furthermore,this will make the debug mode more robust, which means that vendorsmight be more tempted to support it properly, which hasn't been thecase with the current debug mode.This patch shouldn't break any user code, except folks who are buildingagainst a library that doesn't have the debug mode enabled and who tryto enable the debug mode in their code. Such users will get a compile-timeerror explaining that this configuration isn't supported anymore.In the future, we should further increase the granularity of the debugmode checks so that we can cherry-pick which checks to enable, like wedo for unspecified behavior randomization.Differential Revision: https://reviews.llvm.org/D122941 List of files: /llvm-project-15.0.7/libcxx/cmake/caches/Generic-debug-mode.cmake Fri, 01 Apr 2022 20:38:30 +0000 Louis Dionne <ldionne.2@gmail.com>
