sys/i386/i386 db_trace.c
Log:
MFC rev. 1.71, 1.72:
Guess the number of arguments to a function somewhat better.
Now GCC likes to stick a "mov %eax, %FOO" instruction before
"addl $BAR, %esp" if the function just called returns an int,
which is a very common case in the kernel.
Return -1 from db_numargs() if number of args couldn't be guessed.
Use this later to indicate in backtrace output that args shown are
uncertain.
