+ * config/sparc/sol2.h (ASM_DECLARE_OBJECT_NAME): New. Emit
+ "tls_object" for thread-local objects.
+ * config/sparc/sparc.c (sparc_elf_asm_named_section): Emit
+ "#tls" for thread-local sections.
+ * configure.ac (thread-local checks): Specify --fatal-warnings in
+ every binutils-specific checks. For sparc*-*-*, test whether the
+ OS is Solaris and the tools are native and act accordingly.
+ * configure: Rebuild.
