I think it'd be good

As for the equiv sets - yes, that's known. I wanted to investigate
at some point what happens if we instead record the SSA name we

That function doesn't compute reverse post-order of the CFG, but a
post-order of the reverse CFG!
Ok, well - then that's what we need for compute_antic to have

Actually, the only thing that really blows up is that enemy of scalability,
VRP.
FWIW, this appears to be
This removes the need for FRE to compute AVAIL_OUT which can
consume an unreasonable amount of memory for testcases like
int foo (int a)
{
int b = 0;
#define X if (a) b = b + 1;
#define XX X X X X X X X X X X
#define XXX XX XX XX XX XX XX XX XX XX XX
#define XXX XXX XXX XXX XXX XXX XXX
