This patch adds the following target floating-point routines: - target_float_binop - target_float_compare which call the equivalent decimal_ routines to handle decimal FP, and call helper routines that currently still go via DOUBLEST to handle binary FP (derived from current valarith.c code). These routines are used to handle both binary and decimal FP types in scalar_binop, value_equal, and value_less, mostly following the method currently used for decimal FP. The existing value_args_as_decimal helper is renamed to value_args_as_target_float and extended to handle both binary and decimal types. The unary operations value_pos and value_neg are also simplified, the former by using a simple copy for all scalar types, the latter by using value_binop (... BINOP_SUB) to implement negation as subtraction from zero. ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c: Include <math.h>. (floatformat_binop): New function. (floatformat_compare): Likewise. (target_float_binop): Likewise. (target_float_compare): Likewise. * target-float.h: Include "expression.h". (target_float_binop): Add prototype. (target_float_compare): Likewise. * valarith.c: Do not include "doublest.h" and "dfp.h". Include "common/byte-vector.h". (value_args_as_decimal): Remove, replace by ... (value_args_as_target_float): ... this function. Handle both binary and decimal target floating-point formats. (scalar_binop): Handle both binary and decimal FP using value_args_as_target_float and target_float_binop. (value_equal): Handle both binary and decimal FP using value_args_as_target_float and target_float_compare. (value_less): Likewise. (value_pos): Handle all scalar types as simple copy. (value_neg): Handle all scalar types via BINOP_SUB from 0. * dfp.c (decimal_binop): Throw error instead of internal_error when called with an unsupported operation code.
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.
