-Subject: [PATCH] [cmake] Pass -Wl,-z,nodelete on Linux to prevent unloading
-
-Prevent unloading shared libraries on Linux when dlclose() is called.
-This is necessary since command-line option parsing API relies on
-registering the global option instances in the option parser instance
-which can be loaded in a different shared library.
-
-Given that we can't reliably remove those options when a library is
-unloaded, the parser ends up containing dangling references. Since glibc
-has relatively complex library unloading rules, some of the LLVM
-libraries can be unloaded while others (including the Support library)
-stay loaded causing quite a mayhem. To reliably prevent that, just
-forbid unloading all libraries -- it's a very bad idea anyway.
-
-While the issue arguably happens only with BUILD_SHARED_LIBS, it may
-affect any library reusing llvm::cl interface.
-
-Based on patch provided Ross Hayward on https://bugs.gentoo.org/617154.
-Previously hit by Fedora back in Feb 2016:
