tstellar added a comment to D43348: Make FastMathFlags bitcode serialization to match LLVM 5.0 layout.

Is this something we need to get into the 6.0.0 release?

tstellar added a comment to D43070: Add an instruction to avoid cgo compilation error from Go 1.9.4.

Is this a candidate for the 6.0.0 release?

tstellar accepted D41969: [AMDGPU] stop image_store being moved illegally.

As is, this patch is fine. Other improvements can be done as follow on work.

tstellar added a comment to D41969: [AMDGPU] stop image_store being moved illegally.

I think changing AMDGPUImagePseudoSourceValue::isAliased() to return true may fix this.

This is the most conservative way to fix it. I think the better way to fix this would be to change AMDGPUImagePseudoSourceValue::mayAlias() to true. You could improve this even further by making sure that image instructions that reference the same resource have the same PseudoSourceValue. ScheduleDAGInstrs::buildSchedGraph() is where all the dependencies are calculated.

That images have the same resource argument do have the same PSV now. I think the issue may be the non-constant offsets in the intrinsics aren't represented anywhere

tstellar added a comment to D41723: Introduce the "retpoline" x86 mitigation technique for variant #2 of the speculative execution vulnerabilities disclosed today, specifically identified by CVE-2017-5715, "Branch Target Injection", and is one of the two halves to Spectre...

Also, does this mitigation require the use of lld or is there a way to make this work with gnu ld ?

Does this CVE affect all previous versions of clang/llvm ?
