Current status:
alpha-netbsd:
* sigtramp_offset, pc_in_sigtramp: 1.4, 1.5, 1.6, post-1.6
* sigcontext_addr: post-1.6
* skip_sigtramp_frame: post-1.6
arm-netbsd*:
* no signal support yet
i386-netbsd*:
* pc_in_sigtramp: 1.6, post-1.6
In 1.4 and 1.5, %fs and %gs are futzed with in the frame,
and things change based on the presence of the VM86 option.
* sigcontext_addr: 1.4, 1.5, 1.6, post-1.6
m68k-netbsd*:
Needs overhaul -- ignoring this for now.
mips-netbsd:
* pc_in_sigtramp: 1.4, 1.5, 1.6, post-1.6
* sigcontext_addr: MIPS target does not use this. But it is
worth noting that post-1.6, there is no longer a 16-byte gap
before the sigcontext structure.
ns32k-netbsd:
Needs overhaul -- ignoring this for now.
powerpc-netbsd:
* no signal support yet
sh-netbsd:
* pc_in_sigtramp: post-1.6
This target needs more attention paid to it, in general.
sparc*-netbsd*:
* pc_in_sigtramp: post-1.6
Signal trampolines on NetBSD/sparc are nearly impossible
to identify because they're so huge. Consider comparing
addresses on this platform (VM layout can't really change
on Sun4/Sun4c/Sun4m [except MicroSPARC-IIep]).
This target needs more attention paid to it, in general.
