This patch is not ready yet since currently we don't have a pull request under rvv-intrinsic-doc to match to this. The pull request will be created in the near future.



================
Comment at: clang/test/CodeGen/RISCV/rvv-intrinsics-overloaded/vcompress.c:514
 // CHECK-RV64-NEXT:  entry:
-// CHECK-RV64-NEXT:    [[TMP0:%.*]] = call <vscale x 1 x i32> @llvm.riscv.vcompress.nxv1i32.i64(<vscale x 1 x i32> poison, <vscale x 1 x i32> [[SRC:%.*]], <vscale x 1 x i1> [[MASK:%.*]], i64 [[VL:%.*]])
-// CHECK-RV64-NEXT:    ret <vscale x 1 x i32> [[TMP0]]
----------------
The change from `poison` to `undef` is due to value filled in back in the default under `RISCVVEmitter.cpp`. I will have another patch amend this and rebase this patch upon the fix.
