Chris Lattner 085c521fe2 Fix some nasty callgraph dangling pointer problems in ... argpromotion and structretpromote. Basically, when replacing a function, they used the 'changeFunction' api which changes the entry in the function map (and steals/reuses the callgraph node). This has some interesting effects: first, the problem is that it doesn't update the "callee" edges in any callees of the function in the call graph. Second, this covers for a major problem in all the CGSCC pass stuff, which is that it is completely broken when functions are deleted if they *don't* reuse a CGN. (there is a cute little fixme about this though :). This patch changes the protocol that CGSCC passes must obey: now the CGSCC pass manager copies the SCC and preincrements its iterator to avoid passes invalidating it. This allows CGSCC passes to mutate the current SCC. However multiple passes may be run on that SCC, so if passes do this, they are now required to *update* the SCC to be current when they return. Other less interesting parts of this patch are that it makes passes update the CG more directly, eliminates changeFunction, and requires clients of replaceCallSite to specify the new callee CGN if they are changing it. llvm-svn: 80527		2009-08-31 00:19:58 +00:00
