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.

it means that it will not be able to recognize and parse this odd syntax.

zero means that the special parser is deferring the parsing to the generic
