but then you might as well just do:
#define ARM_SIGRETURN 119
How about using __NR_sigreturn and __NR_rt_sigreturn directly? like
what patch #6 does.
Those are host/native macros. Only make sense for the running host.
Can't use that in a tdep file, like arm-linux-tdep.c. Otherwise, e.g.,
a x86-hosted cross debugger would be using the x86 __NR_sigreturn, etc.
Exactly that's why I use those only in GDBServer.
Personally while I like the #define ARM_SIGRETURN 119 better, I think
the xml function is fine.
