[SelectionDAG] Assertion due to MachineMemOperand flags difference.
...o the FoldingSetNodeID. 3) Something else I haven't considered. I have a patch posted implementing 2, but don't know if I should look at fixing 1 as well (or perhaps instead). The loads that trigger the assertion are: t47: v4i32,ch = load<LD16[%0+80](align=8)(dereferenceable)> t20, t46, undef:i64 t69: v4i32,ch = load<LD16[FixedStack1+80](align=8)> t50, t46, undef:i64 I would expect the the second load should also be marked dereferenceable since its loading from one of the TargetFrames. Am I on the right track here? Thanks Sean -------------- next part -------------- Initi...

How to constraint instructions reordering from patterns?
Hi, Is there a kind of scope mechanism in the instruction lowering pattern language in order to control where instructions are inserted or how they are later reordered during the SelectionDiag linearization? I know the glue chain that stick instructions together. But such mechanism in not provided in instruction lowering pattern. I'm facing many situations where some patterns are lowered into

TableGen - Help to implement a form of gather/scatter operations for Mips MSA
Hello. Will, thanks a lot for pointing me to the MaskedGatherSDNode and mgatherv4i32. I have to say that the definition of the "multiclass avx512_gather" from lib/Target/X86/X86InstrAVX512.td is difficult to follow and I prefer not to use it. I currently have some serious problems with TableGen - it gives an assertion failure:

Your data frame fam contains factors. Turn it into character strings using fam$Family = as.character(fam$Family) and try again. It may be helpful if you read up on R's factors, see ?factor.
