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:

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.

/* This enum represents the signals' numbers on a generic architecture
|
|
|
|
running the Linux kernel. The definition of "generic" comes from
|
|
|
|
the file <include/uapi/asm-generic/signal.h>, from the Linux kernel
|
|
|
|
tree, which is the "de facto" implementation of signal numbers to
|
|
|
|
be used by new architecture ports.
|
|
|
|
|
|
|
|
For those architectures which have differences between the generic
|
|
|
|
standard (e.g., Alpha), we define the different signals (and *only*
|
|
|
|
those) in the specific target-dependent file (e.g.,
|
|
|
|
alpha-linux-tdep.c, for Alpha). Please refer to the architecture's
|
|
|
|
tdep file for more information.
|
|
|
|
|
|
|
|
ARM deserves a special mention here. On the file
|
|
|
|
<arch/arm/include/uapi/asm/signal.h>, it defines only one different
|
|
|
|
(and ARM-only) signal, which is SIGSWI, with the same number as
|
|
|
|
SIGRTMIN. This signal is used only for a very specific target,
|
|
|
|
called ArthurOS (from RISCOS). Therefore, we do not handle it on
|
|
|
|
the ARM-tdep file, and we can safely use the generic signal handler
|
|
|
|
here for ARM targets.
|
|
|
|
|
|
|
|
As stated above, this enum is derived from
|
|
|
|
<include/uapi/asm-generic/signal.h>, from the Linux kernel
|
|
|
|
tree. */

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.

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.
