; RUN: llc < %s -asm-verbose=false -verify-machineinstrs -disable-wasm-fallthrough-return-opt -wasm-disable-explicit-locals -wasm-keep-registers

; Regression test for PR40267. Tests that invalid indices in
; extract_vector_elt can be handled when vectors ops are split. Notice
; that SIMD is not enabled for this test. Check only that llc does not
; crash, since it would previously trigger an assertion.
