Description Mathieu Belanger 2017-03-07 17:41:19 UTC

Hi,
EVE-Online don't start anymore since I upgraded to last Mesa GIT and LLVM git two days ago. The game start, Like you see the black screen and the login loading bar and then it crash with that error.

void llvm::LiveRangeEdit::eliminateDeadDef(llvm::MachineInstr*, llvm::LiveRangeEdit::ToShrinkSet&, llvm::AliasAnalysis*): Assertion `MI->allDefsAreDead() && "Def isn't really dead"' failed.

From the LLVM bugs, It got reported last years but nothing append because "this path is not used by default"

https://bugs.llvm.org//show_bug.cgi?id=31015

I don't know if it's the same and/or if I have to post that on the llvm bugs (waiting for a login as they allow people to register on there bugzilla).

Note : It do work (but unplayable in 4K) without Gallium-9.

Can you check if it's due to Mesa or LLVM, then bisect the one that triggered it?

Comment 2 Mathieu Belanger 2017-03-09 04:04:39 UTC

Work fine with LLVM4-rc3 ang mesa git so I assume the but is in LLVM.

Where do I post LLVM bisect if I do it as I did not yet get a response for manually subscribe to the bugzilla?

Comment 3 Michel Dänzer 2017-03-09 06:17:23 UTC
