Okay, upon popular request, I spend a bit this evening (well, night)
actually going ahead with that idea, while trying to not make
it much harder to debug, even without a pretty printer...
The main change compared to what I suggested before, is to
not make the object empty as quoted above, but actually give it
some fields:
struct target_signal_o
{
int number;
const char *name;
const char *string;
};
I think this removes the "much" from much harder to debug. It
may even remove the "harder". See further below for example debugging-gdb
snippets.
The rest of the idea remains. A target_signal_o array to hold
all the possible gdb signals, and a target_signal becomes:
typedef const struct target_signal_o * target_signal;
The TARGET_SIGNAL_... we all know and love become things like:
extern const target_signal TARGET_SIGNAL_0;
...
extern const target_signal TARGET_SIGNAL_TRAP;
...
defined as:
const target_signal TARGET_SIGNAL_0 = &signals[0];
...
const target_signal TARGET_SIGNAL_TRAP = &signals[5];
...
This has the advantage that we get compile time warnings/errors
when we mess up host signals with gdb signals, and, there is
no need for all those comparision macros. Even LT and GT comparisons and
through the signals are allowed:
for (target_signal sig = TARGET_SIGNAL_FIRST; sig < TARGET_SIGNAL_LAST; sig++)
I ended up borrowing a couple of macros from Jan's patch, like
TARGET_SIGNAL_NUMBER.
At debug-your-favorite-program time, you'd now simply dereference the
target_signal pointer to see what it is, instead of the previous suggested
macro magic:
Breakpoint 3, linux_nat_resume (ops=0xbdcbc0, ptid=..., step=1, signo=0x810ac0) at ../../src/gdb/linux-nat.c:1872
1872 if (debug_linux_nat)
(top-gdb) p *signo
$1 = {number = 0, name = 0x80fb80 "0", string = 0x80fb82 "Signal 0"}
which is a big harder than the status quo, but not umbearable-kind-of-hard,
I think. On the bright side, you get to see the signal name and description
right there on the spot:
(top-gdb) p *inferior_thread ()->stop_signal
$6 = {number = 5, name = 0x80fbd2 "SIGTRAP", string = 0x80fbda "Trace/breakpoint trap"}
I only went as far as making it possible to build gdb on x86_64-unknown.linux-gnu.
Anyway, here it is at least for the archives.
