_TLS_Alignment

char _TLS_Alignment[]

extern

The TLS section alignment.

This symbol is provided by the linker command file as the maximum alignment of the .tdata and .tbss sections. The linker ensures that the first TLS output section is aligned to the maximum alignment of all TLS output sections, see function _bfd_elf_tls_setup() in bfd/elflink.c of the GNU Binutils sources. The linker command file must take into account the case that the .tdata section is empty and the .tbss section is non-empty.
