Thanks. Attached patch summarizes what I've done so far on i386 for
compilation to succeed. But one thing remains unresolved:
cc1: warnings being treated as errors
In file included from
In function 'dtrace_debug_lock':
warning: implicit declaration of function 'dtrace_cmpset_long'
warning: nested extern declaration of 'dtrace_cmpset_long'
*** Error code 1
I see that in dtrace_debug.c definition of dtrace_cmpset_long() is
enclosed in #if defined(__amd64__) and there is no such definition for
i386. If I make gcc ignore errors, the kernel does not boot: it
complains on unresolved symbol 'dtrace_cmpset_long'.
