[PATCH] D135324: [AArch64-SVE]: force using SVE in streaming mode to lower arithmetic and logical fixed-width vector ops.

[Hassnaa Hamdi via Phabricator via llvm-commits]

hassnaa-arm added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:22383
+  assert(useSVEForFixedLengthVectorVT(
+             VT, Subtarget->forceStreamingCompatibleSVE()) &&
          "Only expected to lower fixed length vector operation!");

Sorry, I don't understand.
you mean dropping the call for `useSVEForFixedLengthVectorVT(...) `?
or you mean using use `SVEForFixedLengthVectorVT(VT)` without passing the ovrrideNEON parameter ?
