Binutils with MCST patches

Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits SIZE bytes filled with no-op instructions. SIZE is absolute expression. The optional CONTROL byte controls how no-op instructions should be generated. If the comma and @var{control} are omitted, CONTROL is assumed to be zero. For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size limit of a single no-op instruction. The valid values of CONTROL byte are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode, between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit is set to the maximum supported size. 2 new relax states, rs_space_nop and rs_fill_nop, are added to enum _relax_state, which are similar to rs_space and rs_fill, respectively, but they fill with no-op instructions, instead of a single byte. A target backend must override the default md_generate_nops to generate proper no-op instructions. Otherwise, an error of unimplemented .nop directive will be issued whenever .nop directive is used. * NEWS: Mention .nop directive. * as.h (_relax_state): Add rs_space_nop and rs_fill_nop. * read.c (potable): Add .nop. (s_nop): New function. * read.h (s_nop): New prototype. * write.c (cvt_frag_to_fill): Handle rs_space_nop and rs_fill_nop. (md_generate_nops): New function. (relax_segment): Likewise. (write_contents): Use md_generate_nops for rs_fill_nop. * config/tc-i386.c (alt64_11): New. (alt64_patt): Likewise. (md_convert_frag): Handle rs_space_nop. (i386_output_nops): New function.

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.
