gcc/ChangeLog: * Makefile.in (libgcc-support, libgcc.mvars): Add emutls.c. * builtin-types.def (BT_WORD): Make unsigned. (BT_FN_VOID_PTR_WORD_WORD_PTR): New. * builtins.def (BUILT_IN_EMUTLS_GET_ADDRESS): New. (BUILT_IN_EMUTLS_REGISTER_COMMON): New. * c-decl.c (grokdeclarator): Don't error if !have_tls. * c-parser.c (c_parser_omp_threadprivate): Likewise. * dwarf2out.c (loc_descriptor_from_tree_1): Don't do anything for emulated tls. * expr.c (emutls_var_address): New. (expand_expr_real_1): Expand emulated tls. (expand_expr_addr_expr_1): Likewise. * libgcc-std.ver: Add __emutls_get_address, __emutls_register_common. * output.h (emutls_finish): Declare. * toplev.c (compile_file): Call it. * tree-ssa-address.c (gen_addr_rtx): Check for const-ness of the address before wrapping in CONST. * varasm.c (emutls_htab, emutls_object_type): New. (EMUTLS_VAR_PREFIX, EMUTLS_TMPL_PREFIX): New. (get_emutls_object_name, get_emutls_object_type): New. (get_emutls_init_templ_addr, emutls_decl): New. (emutls_common_1, emutls_finish): New.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
