# Deciding which lanes are killed needs to account for other defs in the

# addVRegDefDeps would encounter the %0.sub0 def and erase %0 from
|
|
# current vreg uses because it shared no lanes with %0.sub1 use on the
|
|
# nop. It then didn't see the lanemask when it reached the second
|
|
# subreg def, and failed to add the necessary dependency between the
|

# asm and S_NOP
