Hello, From what I understand, if I have some code that contains a _Thread_local variable, and I compile it to a shared library, then all accesses to the variable go through __tls_get_addr(). However, if I compile it to a static library, the access happens without that function (on x64, it uses %fs).
My question is: how can I force Clang to use __tls_get_addr() even in static libraries? Compiling with `-fpic`, `-fpie` or `-ftls-model=global-dynamic` doesn't seem to work, neither does futzing around with extern or volatile. Also, I understand that this will cause performance degradation. For reference, here (https://pastebin.com/raw/xUZyAk2h) is the code generated when compiling as Static Library, and here (https://pastebin.com/raw/9Ys6Ey60) is the same with a Shared Library. - Naman Dixit _______________________________________________ cfe-users mailing list cfe-users@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
