Currently, 31-bit gdbserver doesn't support collecting/supplying high GPRs, VX registers, and TDB data. This is not much of a problem now, since machines that have them usually have a 64-bit gdbserver that can be used to debug 31-bit targets just fine. However, with fast tracepoints, it's not possible to use a 64-bit gdbserver with a 31-bit IPA (and thus a 31-bit target), so 31-bit gdbserver has to be used for 31-bit targets. Thus, this patch is needed to allow collecting high GPRs and VX registers on 31-bit targets via fast tracepoints. gdb/gdbserver/ChangeLog: * linux-s390-low.c (s390_num_regs_3264): Define on 31-bit too. (s390_regmap_3264) [!__s390x__]: New global. (s390_collect_ptrace_register): Skip map entries containing -1. (s390_supply_ptrace_register): Ditto. (s390_fill_gprs_high): New function. (s390_store_gprs_high): New function. (s390_regsets): Add NT_S390_HIGH_GPRS. (s390_get_hwcap): Enable on 31-bit. (have_hwcap_s390_high_gprs): Enable on 31-bit. (s390_arch_setup): Enable detection of high GPRs, TDB, VX on 31-bit. Detect NT_S390_HIGH_GPRS. (s390_usrregs_info_3264): Enable on 31-bit. (s390_regs_info): Enable regs_info_3264 on 31-bit. (initialize_low_arch): Initialize s390_regsets_info_3264 on 31-bit. |

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.
