* gas/config/tc-arm.c (thumb32_mode): Rename unified_syntax. All uses changed to match. (COND_ALWAYS): Don't offset. (COND_MASK): Delete. (struct arm_it): Add cond field. (struct asm_opcode): Add tag field. Change some fields to unsigned int and/or to bitfields. (my_get_expression): If unified_syntax, always treat the prefix as optional. (s_thumb32, s_thumb32_func): Delete. (opcode_select, s_force_thumb): Don't set thumb32_mode. (s_syntax): New function. (md_pseudo_table): Update to match. (do_blx, do_iwmmxt_wldstw): Look at inst.cond, not inst.instruction, for the condition. (do_it): New function. (do_t_branch): Get the condition from inst.cond and patch it into the appropriate place. (output_inst): If inst.size == 0, output nothing, but do issue a diagnostic if any. (enum opcode_tag): New set of constants. (opcode_lookup): New function. (md_assemble): Use opcode_lookup. Restructure a little. (conds, OPS0): Adjust comment. (TxCE, TxCM, TUE, TUF): Rewrite. (TCC): Delete. (TxC3, TC3, tC3, TxCM_, C3, C3E): New notational macros. (insns): Use TC3, tC3, or C3, as appropriate, for all instructions where the conditional infix appears after the third letter of the mnemonic. Use TCE for 'b'. Use C3E for 'cmfe' and 'cnfe'. Change 'czbne' to 'cbnz', 'czbeq' to 'cbz'. Use TUE, with a dummy ARM opcode, for all variants of 'it'. * opcodes/arm-dis.c: Change 'czbne' to 'cbnz', 'czbeq' to 'cbz'. * gas/testsuite/gas/arm/thumb.d: bal.n is no longer distinguishable from b.n. * gas/testsuite/gas/arm/thumb32.d: Likewise. Change 'czbne' to 'cbnz', 'czbeq' to 'cbz'. * gas/testsuite/gas/arm/thumb32.s: Use .syntax unified. Change 'czbne' to 'cbnz', 'czbeq' to 'cbz'.
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.
