Currently the ppc linux core file target doesn't return target descriptions with the lager FPSCR introduced in isa205. This patch changes the core file target so that the auxv is read from the core file to determine the size of FPSCR, so that the appropriate target description is selected. gdb/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * arch/ppc-linux-common.c (ppc_linux_has_isa205): Change the parameter type to CORE_ADDR. * arch/ppc-linux-common.h (ppc_linux_has_isa205): Change the parameter type in declaration to CORE_ADDR. * ppc-linux-tdep.c (ppc_linux_core_read_description): Call target_auxv_search to get AT_HWCAP and use the result to get the target description. * ppc-linux-nat.c (ppc_linux_get_hwcap): Change the return type to CORE_ADDR. Remove the cast of the return value to unsigned long. Fix error predicate of target_auxv_search. (ppc_linux_nat_target::read_description): Change the type of the hwcap variable to CORE_ADDR. gdb/testsuite/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * gdb.arch/powerpc-fpscr-gcore.exp: New file.
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.
