It will be used when one wants to convert between the internal GDB signal representation (enum gdb_signal) and the target's representation. The idea of this patch came from a chat between Pedro and I on IRC, plus the discussion of my patches to add the new $_exitsignal convenience variable: <http://sourceware.org/ml/gdb-patches/2013-06/msg00452.html> <http://sourceware.org/ml/gdb-patches/2013-06/msg00352.html> What I did was to investigate, on the Linux kernel, which targets shared the signal numbers definition with the generic definition, present at <include/uapi/asm-generic/signal.h>. For the record, I used linux-3.10-rc7 as the main source of information, always looking at <arch/<ARCH_NAME>/include/uapi/asm/signal.h>. For SIGRTMAX (which defaults to _NSIG in most cases), I had to look at different signal-related files, but most of them (except MIPS) were defined to 64 anyway. Then, with all the differences in hand, I implemented the bits on each target. 2013-08-09 Sergio Durigan Junior <sergiodj@redhat.com> * linux-tdep.c: Define enum with generic signal numbers. (linux_gdb_signal_from_target): New function. (linux_gdb_signal_to_target): Likewise. (linux_init_abi): Set gdbarch_gdb_signal_{to,from}_target methods to the functions above. * linux-tdep.h (linux_gdb_signal_from_target): New prototype. (linux_gdb_signal_to_target): Likewise. * alpha-linux-tdep.c: Define new enum with signals different from generic Linux kernel. (alpha_linux_gdb_signal_from_target): New function. (alpha_linux_gdb_signal_to_target): Likewise. (alpha_linux_init_abi): Set gdbarch_gdb_signal_{to,from}_target with the functions mentioned above. * avr-tdep.c: Define enum with differences between Linux kernel and AVR signals. (avr_linux_gdb_signal_from_target): New function. (avr_linux_gdb_signal_to_target): Likewise. (avr_gdbarch_init): Set gdbarch_gdb_signal_{to,from}_target to the functions mentioned above. * sparc-linux-tdep.c: Define enum with differences between SPARC and generic Linux kernel signal numbers. (sparc32_linux_gdb_signal_from_target): New function. (sparc32_linux_gdb_signal_to_target): Likewise. (sparc32_linux_init_abi): Set gdbarch_gdb_signal_{to,from}_target to the functions defined above. * xtensa-linux-tdep.c: Define enum with differences between Xtensa and Linux kernel generic signals. (xtensa_linux_gdb_signal_from_target): New function. (xtensa_linux_gdb_signal_to_target): Likewise. (xtensa_linux_init_abi): Set gdbarch_gdb_signal_to_target to the functions defined above. * mips-linux-tdep.c: Define enum with differences between signals in MIPS and Linux kernel generic ones. (mips_gdb_signal_to_target): New function. (mips_gdb_signal_from_target): Redefine to use new enum, handle only different signals from the Linux kernel generic. (mips_linux_init_abi): Set gdbarch_gdb_signal_{to,from}_target the functions defined above. * mips-linux-tdep.h (enum mips_signals): Remove. |

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.
