Hi GCC developers,

As ChangeLog-2013 mentioned by Bernd Schmidt: ... pass_ipa_lto_gimple_out
... Remove. Delete.

there is no 'pass_ipa_lto_gimple_out' in lto-streamer-out.c any more.

then how to migrate it for GCC v6.x? just like this:
https://github.com/xiangzhai/dragonegg/blob/gcc-6_3-branch/src/Backend.cpp#L2880
to ignore it?

or do I need to find other equivalent PASS? please give me some hint, thanks
a lot!
It says

// Disable all LTO passes.

(for whatever reason).  So try just removing this part - the pass is
already removed.
Yes, I use the macro (GCC_MAJOR < 5) to disable it (just removing this part, to ignore it) https://github.com/xiangzhai/dragonegg/blob/gcc-6_3-branch/src/Backend.cpp#L2884 sorry I am not the original developer of DragonEgg http://llvm.org/devmtg/2009-10/Sands_LLVMGCCPlugin.pdf and recently I am learning about GCC plugin and GIMPLE https://reviews.llvm.org/D35667 for converting GIMPLE to LLVM IR, then disable GCC PASS but use LLVM's instead, but I don't have the whole view of it, I need to deepin to it more :) please Duncan answer your question about 'for whatever reason', thanks!



Richard.

PS: Thanks for David's hint, I fixed 'undefined symbol
gt_ggc_mx(tree2WeakVH*&)' issue, I forgot to add 'for_user' for
GTY((XXX))...
