* findvar.c (read_var_value): Remove case for thread local storage variables. It is now entirely handled by the dwarf2 location expression code. * printcmd.c (address_info): Ditto. * symtab.h (address_class): Remove LOC_THREAD_LOCAL_STATIC enumeration value. (struct symbol): Remove objfile field, which was used by LOC_THREAD_LOCAL_STATIC only. * dwarf2read.c (decode_locdesc): Remove is_thread_local variable. * dwarf2loc.h (struct dwarf2_loclist_baton): Add comment about usage of objfile pointer. * dwarf2loc.c (locexpr_describe_location): Add case to handle thread local variables. Add include of objfiles.h. * dwarf2expr.c (execute_stack_op): Add comments about thread local storage variables. * Makefile.in (dwarf2loc.o): Update dependencies.
