This patch implements the new gdbarch method gdbarch_gdb_signal_to_target.
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.
