* elf/tls-macros.h: Add Sparc64 defines. * sysdeps/sparc/sparc64/dl-machine.h (sparc64_fixup_plt): Mark as always_inline. (elf_machine_fixup_plt): Likewise. (elf_machine_rela): Handle TLS relocations. (elf_machine_type_cleaa): Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h (SYSCALL_ERROR_HANDLER_ENTRY): Use sethi/or for GOT reloc. It does not always fit in R_SPARC_GOT13 when building -fPIC. Also, add TLS handling. * sysdeps/unix/sysv/linux/configure.in (arch_minimum_kernel): Increase it to 2.4.21 for sparc64. * sysdeps/unix/sysv/linux/sparc/sparc32/clone.S: NULL terminate backtrace by zero'ing out %fp. Store away flags, func_ptr, and func_arg in global registers not local registers. * sysdeps/unix/sysv/linux/sparc/sparc64/clone.S: Handle PTID, TLS, and CTID arguments properly. Add RESET_PID handling. * sysdeps/unix/sysv/linux/sparc/sparc64/pause.c: Rework so that we do not invoke __sigprocmask(). We can always assume rt signals are present on sparc64, so just do an inline syscall. 2005-04-13 Jakub Jelinek <jakub@redhat.com> * sysdeps/sparc/sparc64/dl-machine.h: Add dl_machine_h multiple inclusion guard for the first half of the header. (elf_machine_type_class, ELF_MACHINE_JMP_SLOT, ELF_MACHINE_NO_REL, ELF_MACHINE_PLTREL_OVERLAP, elf_machine_runtime_setup, elf_machine_relplt, DL_STACK_END, RTLD_START): Move into the #ifndef dl_machine_h guarded part of the header.
