Binutils with MCST patches
b593e3d9b0
When `info float` is used on an AMD64 system, GDB prints floating-point values of x87 registers with raw contents like 0x361a867a8e0527397ce0 or 0xc4f988454a1ddd3cfdab wrongly. This happens due to truncation to double, after which the former becomes 0.0, and the latter becomes negative infinity. This is caused by failed detection of x86-64 host, which results in setting gdb_host_{float,double,long_double}_format to zeros. This commit fixes this misdetection, and adds a test to make sure future commits don't introduce a regression here. gdb/ChangeLog: 2015-12-09 Ruslan Kabatsayev <b7.10110111@gmail.com> PR gdb/18702 * configure.host: Fix detection of x86_64 host when setting floatformats. gdb/testsuite/ChangeLog: 2015-12-09 Ruslan Kabatsayev <b7.10110111@gmail.com> Pedro Alves <pedro@redhat.com> PR gdb/18702 Add checking of floatformats setup on x86_64 hosts. * gdb.arch/i386-float.S (main): Load bigval and smallval. (smallval, bigval): New labels/constants. * gdb.arch/i386-float.exp: Use with_test_prefix and test "info float" after loading bigval and smallval. |

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.
