[Bug 1286343]
Good job reducing the testcase to something this small! Anyway, Jakub's analysis of what is going on is still correct and all the high level decisions that we do are IMHO correct too. The invocation of symtab_remove_unreachable_symbols that removes the callers is called with before_inlining_p set to false, even though that is not technically right, we are still in the middle of inlining because we are about to inline functions which are called only once. But the comment in function ipa_inline says this is deliberate because it helps to find the functions which are only called once. However, this means that when symtab_remove_unreachable_symbols correctly figures out that we can devirtualize to the offending thunk, it assumes that cannot lead to any further inlining. Because the thunk is keyed in another compilation unit, it decides it only needs to keep the symtab node but not the body. In its terminology, the node is in the "boundary". The way the function cripples these boundary nodes is actually the problem because it removes all callees but not the thunk flag. This leaves us with a thunk with no callee, something that should not happen (and there is even a bit in the call graph verifier that checks it). Later on, we do perform this devirtualization during inlining of functions only called once and connect the crippled thunk to the call graph. The first time we want to follow through it, we segfault. I believe that we do not want to allow thunks with no callees. This would mean changing every user of cgraph_function_node so that it can cope with NULL return value and that is ugly and inconvenient. This leaves us with two options. Either we make symtab_remove_unreachable_symbols keep callees of thunks when it keeps the thunk or we simply clear the thunk_p flag. Given that thunks and aliases are quite similar and we do clear the alias flag, and that this should only ever affect nodes that we are not going to output, I tend to believe the second approach is OK and of course it is much simpler. But before I propose the following fix on the mailing list, I'll try to build some big C++ application with it: diff --git a/gcc/ipa.c b/gcc/ipa.c index 572dba1..164de0d 100644 --- a/gcc/ipa.c +++ b/gcc/ipa.c @@ -488,6 +488,7 @@ symtab_remove_unreachable_nodes (bool before_inlining_p, FILE *file) node->definition = false; node->cpp_implicit_alias = false; node->alias = false; + node->thunk.thunk_p = false; node->weakref = false; if (!node->in_other_partition) node->local.local = false; -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1286343 Title: mrpt triggers ICE on armf, powerpc, ppc64el at -O2 or higher To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/1286343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1286343]
Created attachment 32321 pr60419.C This is quite impossible to reduce, at least after 4 days of attempting to delta/creduce reduce this I got only to 132KB. Compile with -m64 -O3 -std=c++11. Anyway, it is reduced enough that it compiles (and ICEs in a different place) with x86_64-linux cc1plus, so also shows a bug in slsr, with -m64 -O3 -std=c++11 -fno-tree-slsr it compiles with x86_64 target though and thus I can't bisect this on x86_64. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1286343 Title: mrpt triggers ICE on armf, powerpc, ppc64el at -O2 or higher To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/1286343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
