--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- https://gcc.gnu.org/onlinedocs/gcc-15.1.0/gcc/Common-Variable-Attributes.html#index-tls_005fmodel-variable-attribute The tls_model attribute sets thread-local storage model (see Thread-Local Storage) of a particular __thread variable, overriding -ftls-model= command-line switch on a per-variable basis. The tls_model argument should be one of global-dynamic, local-dynamic, initial-exec or local-exec.
