Proof step 7 from proof bitsor-first-01 (
previous step
)
⊦ bitsor(boolvar ' + bits1, boolvar0 ' + bits) ≠ [], bitsor(boolvar ' + bits1, boolvar0 ' + bits).first ↔ boolvar ∨ boolvar0
Heuristic simplifier applied rule simplifier
And obtained the following new goals
Proof step 8
:
bitsor(boolvar ' + bits1, boolvar0 ' + bits) = [] ⊦ [].first ↔ boolvar ∨ boolvar0
Rule argument
