search for: t121

Hi all, I've been working on a backend of our architecture and noticed llvm performs following combining although one of operands is FrameIndex. Combining: t114: i64 = add FrameIndex:i64<0>, Constant:i64<56> Creating new node: t121: i64 = or FrameIndex:i64<0>, Constant:i64<56> ... into: t121: i64 = or FrameIndex:i64<0>, Constant:i64<56> This caused problem if frame pointer points 0x60000038 at run time. I checked DAGCombiner::visitADD. It folds ADD to OR by following code without considering a...

The deriv() function takes an 'expression' as its first argument). I was wondering if the this function can take an array or a vector of expressions as its first argument. Aside, I saw how to give a vector argument to the second argument. like to have something like: deriv(c(~x^2+y^3, ~x^5+y^6), c("x","y")) the documentation for this function talks about being able to

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:
