literal_syms): New global variables. (xtensa_define_label, add_target_symbol, xtensa_find_label, map_over_defined_symbols, is_loop_target_label, xtensa_mark_target_fragments, xtensa_move_frag_symbol, xtensa_move_frag_symbols, defined_symbols, branch_targets): Delete. (xtensa_begin_directive): Call md_flush_pending_output. Move symbols from insn_labels to saved_insn_labels when entering a literal region. (xtensa_end_directive): Call md_flush_pending_output. Restore insn_labels list when leaving a literal region. (xtensa_literal_position): Call xtensa_clear_insn_labels. (xtensa_literal_pseudo): Add check to disallow .literal inside a literal region. Move insn_labels to saved_insn_labels and then restore insn_labels on exit. (xg_add_branch_and_loop_targets): Replace add_target_symbol calls with code to set is_loop_target or is_branch_target flag on the symbol (xtensa_create_literal_symbol): Call xtensa_add_literal_sym. (xtensa_add_literal_sym, xtensa_add_insn_label, xtensa_clear_insn_labels): New functions. (xtensa_move_labels): Remove old_frag and old_offset arguments. Add loops_ok argument. Rewrite to use insn_labels list instead of calling xtensa_find_label and to check the is_loop_target flag on symbols when loops_ok is false. (xtensa_frob_label): Remove call to xtensa_define_label. Add call to either xtensa_add_literal_sym or xtensa_add_insn_label. Adjust call to xtensa_move_labels. Propagate is_branch_target and is_loop_target flags from symbols to frags. (xtensa_flush_pending_output): Call xtensa_clear_insn_labels. (md_assemble): Use xtensa_move_labels with loops_ok = FALSE when aligning a loop instruction. Adjust call to xtensa_move_labels for aligning entry instructions. Add call to xtensa_clear_insn_labels. (xtensa_end): Remove call to xtensa_mark_target_fragments. (xtensa_move_literals): Replace xtensa_move_frag_symbols call with code to use new literal_syms list. * config/tc-xtensa.h (xtensa_symfield_type): Add is_loop_target and is_branch_target flags.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
