New statics. (OPTION_ELF_BASE): Make room for new option macros. (OPTION_SOFT_FLOAT, OPTION_HARD_FLOAT, OPTION_SINGLE_FLOAT, OPTION_DOUBLE_FLOAT): New option macros. (md_longopts): Add msoft-float, mhard-float, msingle-float and mdouble-float. (md_parse_option): Handle OPTION_SINGLE_FLOAT, OPTION_DOUBLE_FLOAT, OPTION_SOFT_FLOAT and OPTION_HARD_FLOAT. (md_show_usage): Add -msoft-float, -mhard-float, -msingle-float and -mdouble-float. (struct mips_set_options): New fields soft_float and single_float. (mips_opts): Initialized them. Add comment for each field initializer. (mips_after_parse_args): Set them based on file_mips_soft_float and file_mips_single_float. (s_mipsset): Add support for `.set softfloat', `.set hardfloat', `.set singlefloat' and `.set doublefloat'. (is_opcode_valid): New function to invoke OPCODE_IS_MEMBER. Handle single-float and soft-float instructions here. (macro_build, mips_ip): Use it instead of OPCODE_IS_MEMBER. (is_opcode_valid_16): New function. (mips16_ip): Use it instead of OPCODE_IS_MEMBER. (macro) <M_LDC1_AB, M_SDC1_AB, M_L_DOB, M_L_DAB, M_S_DAB, M_S_DOB>: Remove special-casing of r4650. * doc/c-mips.texi (-march=): Add Octeon. (MIPS Opts): Document -msoft-float and -mhard-float. Document -msingle-float and -mdouble-float. (MIPS floating-point): New section. Document `.set softfloat' and `.set hardfloat'. Document `.set singlefloat' and `.set doublefloat'.
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.
