Given that GCC has obsoleted/removed support for Solaris 9 in GCC 4.9/5 in 2013: https://gcc.gnu.org/gcc-4.9/changes.html https://gcc.gnu.org/ml/gcc-patches/2013-05/msg00728.html and the last gdb version that can be compiled with gcc 4.9 is 7.12.1 only when configured with --disable-build-with-cxx, it's time to obsolete/remove support for Solaris < 10. This patch does this, simplifying configure.nat along the way (only a single sol2 configuration with variants for i386 and sparc). Some configure checks for older Solaris versions can go, too, and the check for libthread_db.so.1 removed: * Since Solaris 10, dlopen has moved to libc and libdl.so is just a filter on ld.so.1, so no need to check. * $RDYNAMIC is already handled above (and is a no-op with Solaris ld anyway). Both proc-service.c and sol-thread.c lose support for (Solaris-only) PROC_SERVICE_IS_OLD. The attached revised patch has been tested on sparcv9-sun-solaris2.10, sparcv9-sun-solaris2.11.4, amd64-pc-solaris2.10, amd64-pc-solaris2.11.4, and x86_64-pc-linux-gnu. I've also started an i386-pc-solaris2.9 build to check that it really stops as expected. PR gdb/22185 * configure.host <*-*-solaris2.[01], *-*-solaris2.[2-9]*>: Mark as obsolete. Use gdb_host sol2 for i[34567]86-*-solaris2*, x86_64-*-solaris2*. Remove i386sol2 support. * configure.nat <i386sol2>: Remove. <sol2-64>: Fold into ... <sol2>: ... this. Move common settings to default section. Add sol-thread.o. * configure.tgt <i[34567]86-*-solaris2.1[0-9]*, x86_64-*-solaris2.1[0-9]*>: Rename to ... <i[34567]86-*-solaris2*, x86_64-*-solaris2*>: ... this. <i[34567]86-*-solaris*>: Remove. <sparc-*-solaris2.[0-6], sparc-*-solaris2.[0-6].*>: Remove. * configure.ac: Remove wctype in libw check. (_MSE_INT_H): Don't define on Solaris 7-9. <solaris*>: Remove libthread_db.so.1 check. * configure: Regenerate. * config.in: Regenerate. * proc-service.c: Remove PROC_SERVICE_IS_OLD handling. (gdb_ps_prochandle_t, gdb_ps_read_buf_t, gdb_ps_write_buf_t) (gdb_ps_size_t): Remove. Use base types in users. * sol-thread.c: Likewise, also for gdb_ps_addr_t. * NEWS (Changes since GDB 8.0): Document Solaris 2.0-9 removal. |

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.
