I am seeing exactly the same on x86_64-unknown-linux-gnu (using
--disable-libvtv since that is broken too).

I've found a minor error in the tree-ssa-threadedge.c changes. I can easily
see how it affects Zhengong's testcase and I can speculate how it might be
triggering the ia64 failure.
I'm testing it on x86_64-unknown-linux-gnu at the moment. I'll spin up a test
on ia64 at some point over the weekend as well.

I'm seeing ia64 fail with an insn does not match constraints failure when the
stage2 compiler builds the stage2 C++ runtime. And that's *with* the fix I
checked in last night. That smells like stage1 mis-compiled stage2.
So I'm going to keep this open while I track down that regression.
There's another ICE I'm aware of (pr58343), but I don't see the root cause of
that PR causing a mis-compilation, just ICEs for certain degenerate cases.

Andreas,
ia64 is bootstrapping fine for me. I did one immediately before installing the
patch to fix this PR and just did another one (r202530 of the trunk on
ia64-unknown-linux-gnu)
I'm going to need more information to be able to proceed any further with your
ia64 issues.
