Alright, thanks for the archeological digging.
I still I'm not sure what exactly this all means: if compat_ibcs2 is in
compat_svr3, and if the real iBCS2 implementation is in fact
is compat_svr4 doing on sparc/sparc64?
Our IBCS2 is SVR3 (compat_imbcs2) and SVR4 (compat_svr4).
Ok. So if I sum up correctly:
- compat_ibcs2 should have been called compat_svr3, and our x86-specific
iBCS2 implementation is in fact spread across compat_svr3 and compat_svr4.
In order to fully benefit from iBCS2, you needed to have both options turned
- sparc and sparc64 use compat_svr4 for compatibility with Solaris.
- vax uses compat_ibcs2 (=compat_svr3) for compatibility with SVR3.
This is a mess.
