The first change in GCC which changed signed overflow/wrapping to be
undefined
was added back in 1992 in loop.c. The next change was in 1999 with the
addition of simplify-rtx.c. Why are we talking about this now, instead
of back
when they were added? (note both of these changes were before fwrapv
can into
play).
